The Evansville Water and Sewer Utility (EWSU) in

Evansville, Indiana, supplies 32 million gallons of water per

day to 60,000 commercial and residential customers. EWSU

also handles all wastewater treatment, sanitary and com-

bined sewer systems for the City of Evansville. Over the

past two years, EWSU has

been updating its systems

for automation and infor-

mation technology.

InGen Technologies, a

Semaphore Authorized

Solutions Partner, is the sys-

tems integrator for both the

SCADA and IT portions of

the upgraded system. Scope-

of-work for InGen includes

monitoring of 22 combined

sewage overflow manholes,

SCADA for 84 lift stations and other remote points, new

automation systems for three filtration plants, Motorola Canopy

wireless communications network and the central data center.

The monitoring of combined sewage overflow (CSO) is

used for public notification. Environmental Protection Agency

(EPA) regulations require utilities to monitor, generate reports

and immediately notify the public about any overflow events.

The objective was to automate the data collection process.

Before this project, EWSU employees had to travel to each of

22 locations and read the historical data in level/flow meters

using low power, drive-by wireless technology. This process

took an entire day and didn’t meet the real-time notification

mandated by the EPA.

At these locations, InGen decided to keep in place the exist-

ing Teledyne ISCO battery-

powered, ultrasonic area-

velocity flowmeters.

According to Mike Halbig,

president of InGen, “The

ISCO flowmeters were

doing a great job under

some pretty tough environ-

mental conditions.”

For automated data col-

lection, InGen installed

Semaphore’s T-Box RTU

products on nearby 40-foot

poles and ran wired, serial Modbus connections to the meters.

T-Box combined communications and control with onboard

data collection, trending, alarming and long-term data storage,

all in one, low power consuming package.

At such remote installations, the IP forwarding capability of

T-Box provides a key advantage. Over a serial connection, T-

Box can collect real-time and historical information from

intelligent end devices and forward it on an IP network.

Pepperl+Fuchs IntroducesCorrosion Data Logging SystemFor its CorrTran MV CorrosionDetection Transmitters

Pepperl+Fuchs has intro-

duced the CorrTran corrosion

data logging system. This

Division 2 / Zone 2 corrosion

data logging system comple-

ments the CorrTran MV

online corrosion monitoring

transmitter, allowing users to

access real-time corrosion

data via Ethernet, USB, SD

card, or locally via video-

graphic chart recorder. The

corrosion data logging system

is packaged in a portable, stainless steel enclosure

weighing less than 20 lbs.

“CorrTran MV represents an advancement in internal

corrosion monitoring by detecting and measuring,

online and in real-time, the presence of general corro-

sion, as well as pitting corrosion and conductance. The

transmitter outputs a 4 to 20 mA HART signal that is

used to scale the corrosion rate in a PLC or DCS system.

The key advantage here is that the rate of corrosion can

now be evaluated with all other relevant process sig-

nals,” said Jason Norris, product manager,

Pepperl+Fuchs. “It has always been known that specif-

ic process conditions will cause increased rates of corro-

sion but often this is known after-the-fact. Imagine con-

trolling corrosion inhibitors, and thus, controlling costs,

by viewing corrosion data online, and in real time.”

The corrosion data logging system includes

Pepperl+Fuchs’ KFD2-HLC-EX1.D HART loop convert-

er. This device receives HART data from the CorrTran

MV corrosion monitor and delivers three distinct 4 to 20

mA outputs that represent general corrosion, localized

corrosion and conductance. These three variables can then

be recorded and displayed on a paperless data recorder

that features a full color touch screen display, up to 16

analog inputs, multiple types of media retrieval and a

Class I/Div 2, Zone 2 Ex-hazardous rating.

A Type 4X stainless steel enclosure allows for the

most severe of installations. The lightweight construc-

tion also permits easy mobility for the system to be

moved from one location to another, where a PLC/DCS

might not be available.

Phoenix Broadband ReleasesExpandable Monitoring System

Phoenix Broadband Technologies has introduced its

new ContactAgent expandable, modular monitoring sys-

tem. The system con-

sists of the

ContactAgent mas-

ter unit, which has

eight user-defined

contact inputs and

two user-control-

lable relay outputs.

The capability of the

master unit is

expanded by up to

eight RIM (remote

input module) and

ROM (remote output module) slave modules. RIM and

ROM units connect to the ContactAgent master unit

with commonly available CAT-5 ethernet cables.

The master unit provides power to the slave units and

communicates with them over the daisy chain. Each

RIM adds six additional contact or analog inputs to the

system, and each ROM adds four controllable latched

Form-C relay outputs. Each slave module also has tem-

perature and humidity sensors built-in, as well as an

included AC mains voltage sensor.

The ContactAgent master unit is ethernet network-

able and supports common TCP/IP protocols including

HTTP, SMTP, DHCP, TFTP and SNMP. The unit has a

built-in web server that implements complete monitor-

ing, control and configuration capabilities, as well as an

email client that can send alarm messages to several

recipients. Alarms are user definable and any input can

measure analog voltages with user-defined alarm thresh-

olds. The unit can also be monitored and controlled by

any SNMP compliant software.

Sixnet has released its IPm2m RTU and data logger allowing for real-time infor-

mation anytime and anywhere. IPm2m is a combination of RTU, data

logger and telemetry interface in a compact installation-ready pack-

age. Sixnet has bundled 30 years of I/O technology into this upscale

and capable product.

The IPm2m has a full complement of communication ports with

an Ethernet, RS232, RS485 and USB. This port configuration

makes it well suited for connecting to just about any device in a

remote location. Each port supports Sixnet and Modbus protocol

along with DNP3 slave. A diverse mixture of discrete and analog

I/O is a good fit for remote monitor and control of various instru-

ments. Additionally, data logging memory of 32 MB in flash or

dynamic memory provides space to save important data that can be

accessed at any time.

Uninterruptible power protection supplies backup power from a central location

to each distributed Etherbus I/O module using a single Etherbus

Fieldbus cable. The Etherbus PoE supply feature will keep the mod-

ule communicating and powering critical instrumentation during a

power failure.

IPm2m provides the means to connect remotely to bring real-time

data from distributed locations to the Internet or into a central infor-

mation server. This product is designed for remote M2M applications

such as environmental monitoring, energy/facility management, criti-

cal equipment monitoring, resource tracking and control, automated

field service and security systems.

The operating temperature range is -40°C to 75° C (-40°C to 85°C

storage) and IPm2m modules are ISO9001, CUL, UL DNV, CE, FCC

and RoHS rated to assure their long term performance.

Emerson Unveils Two-Wire Micro Motion CoriolisMeter for Loop-Powered Processes

Emerson Process Management has introduced the first two-wire Micro Motion

Coriolis meter, expanding the value of Coriolis to

the wide range of applications that require loop-

powered flow devices. The Coriolis meters are

designed for upgrading older loop-powered

technologies to Elite Coriolis meters without

adding more power or installing new cabling.

Having benefitted from Coriolis technology

in the past, process engineers and managers have

wanted a meter they could use more broadly.

They have used Micro Motion Coriolis four-

wire devices because of their measurement per-

formance for batching, custody transfer, two-phase

flow in challenging applications. Fortunately, innovation has now realized the two-wire

Micro Motion Coriolis is also well suited for loop-powered flow points throughout the

plant where the process can benefit from increased accuracy and reliability of Coriolis.

The new two-wire meter delivers measurement accuracy, repeatability and opera-

tional savings on a level not previously possible for flow loops with older flow meas-

urement technologies. The meter delivers +0.10 percent liquid flow and +0.0005 g/cm3

ATEN Technology’s Serial Device Server Supports RS-232, RS-422 and RS-485 Data Transfers

ATEN Technology, Inc. has release a new serial device server that enables secure,

remote management of IT serial devices such as servers, routers, PBX systems,

telecommunications equipment, serial-based power

management appliances and more. The serial over the

NET (SN3101) three in one Serial Device Server sup-

ports RS-232, RS-422 and RS-485 data transfers, as

well as provides Ethernet connectivity for a wide variety

of serial devices used in commercial applications. These

applications include industrial control, data acquisition,

access control, environment monitoring, telecommuni-

cations and remote site management. This all-encom-

passing serial data transfer system transforms the usabil-

ity of legacy serial devices by enhancing them with the

speed and reliability of the most current communica-

tions interfaces.

The SN3101 features Real COM Port support which allows devices connected to this

"virtual" port to appear as though they are directly connected to a COM port on a local

computer. This feature adds value for users of POS terminals, barcode readers and seri-

al printers.

The SN3101 single-port device is well suited for industrial control of programmable

logic controllers (PLCs), meters and sensors. The SN3101 supports versatile, diversi-

fied serial data access operations to meet a broad range of application requirements

(console management, Real COM, TCP Server, TCP Client, UDP, Modbus, Serial

Tunnel and Virtual Modem). This capability offers direct access from PCs to remote

serial devices as if these products were located locally and reduces the typical port

number and distance limitations of PC hardware.

The provided Windows utility auto-discovers all SN3101 units in a local area net-

work (LAN) and permits configuration/monitoring of one or multiple SN3101s at once,

making mass deployment simple. In addition, users can receive event notification for

proactive monitoring and response due to the unit's support for SMTP and SNMP traps.

The unit offers secure data transmission, centralized access control and Modbus

Ethernet-to-Serial support. The SN3101 offers a variety of over IP methods to control seri-

al devices that range from browser login to a stand-alone serial network device manage-

ment AP program to Telnet/SSH terminal access. Recognizing the importance of secure

data transmission to operations, the SN3101 provides 128-bit SSL serial data encryption

for TCP Server, TCP Client, Virtual Modem and Serial Tunnel operation modes.

Administrators can authenticate user logins and authorize individual user rights via

RADIUS, LDAP, LDAPS and Microsoft Active Directory servers. The SN3101's sup-

port for Modbus Ethernet-to-serial data transmission provides a bridge that seamlessly

integrates Modbus devices (PLCs, DCSs, HMIs, etc.) into any serial network.

dresden elektronik Teams Up with MeshNetics toDevelop ZigBee-Based Building Automation Solution

dresden elektronik ingenieurtechnik gmbh and

MeshNetics have launched a ZigBee-based building

automation solution. This new system, powered by

MeshNetics’ ZigBit 802.15.4/ZigBee wireless modules,

enables wireless lighting control, integration of electricity,

gas and water meters, and more.

The system consists of three components. First is the

deFZ 3000 wireless control unit for remote control, moni-

toring and visualization of the network and data transmis-

sion. The second component enables building automation.

This is the LS8 light switch unit and LL1 light load controller. Last are the automated

meter reading modules, the HM1 heat meter and DSI1 wireless digital sensor.

The deFZ 3000 central wireless control unit coordinates the functioning of all devices

in the home or factory network. The unit boasts a 3.5 inch color graphics LCD display

and touch screen for access to network setup, maintenance, reconfiguration and other

functions. Measurement values and historic data can be stored both locally and external-

ly. Security functions with automatic alerts via SMS/GPRS are an option, while integrat-

ed web server allows remote control and visualization.

Enabling components for building automation include the LS8, a ZigBee-based

light switch unit that facilitates wireless switching and dimming of the lights which

can be used with one, two or four key tops from a variety of manufacturers. The LL1,

a mains-powered light load controller, can switch all 230 V power components and

make power consumption measurements, all while doubling as a router in the ZigBee

wireless sensor network.

Smart metering is further simplified with the wireless digital sensor DSI1. This

miniature device can be integrated with most of the electricity, water, gas and heat

meters available on the market. The ZigBee-enabled DSI1 sensor device counts, accu-

mulates and transmits impulses as delivered by metering outputs. In addition, dresden

elektronik offers the HM1 heat meter, which measures heat consumption by continu-

ously monitoring water inlet and outlet temperature and flow.

Programmable Controller Improves Performance,Capacity and Connectivity

Phoenix Contact has introduced the nanoLine, a small programmable con-

troller/relay with Ethernet connectivity, a removable operator display and easy flow

chart programming. The nanoLine is designed to control small to midsize machines

that require few I/O points.

Base controller stations are available in 24 V DC, 24 V AC/DC and 115 V AC ver-

sions. The on-board I/O consists of digital inputs and outputs. The nanoLine accom-

modates up to three I/O expansion modules, bringing the total possible I/O count to 24

digital inputs and 16 digital outputs.

The nanoLine offers a variety of optional expansion modules, increasing its flexibil-

ity. Communication modules for Ethernet, RS-232, RS-485 and USB allow easy data

exchange with Modbus TCP or Modbus RTU. The optional operator panel can be

mounted on the base unit, through a control cabinet or used as a simple hand-held

device. Pluggable memory and real-time clock modules are also available.

The nanoLine controller uses nanoNavigator software, an intuitive flow chart language

that allows for easy programming and hardware configuration. The user can create the con-

trol logic with six simple instructions. Most programs can execute under one millisecond.

“We equipped each T-Box with a Motorola 900 MHz ‘subscriber module’ radio that

communicates with Motorola Canopy wireless access points installed on top of three

water towers throughout the city,” said Halbig, “The ISCO

flowmeters indicate how much, if any, combined wastewater is

being diverted to the Ohio River, and the T-BOXes upload this

information in real time via the wireless umbrella to a secure

server in the utility’s central data center. If for any reason, the

wireless link is lost, the individual T-Boxes retain the data until

it can be uploaded.”

InGen also employed the T-Box integral webserver in an

interesting manner. While the webserver normally provides the

HMI functionality in a decentralized SCADA system, EWSU’s

system was already in operation with a centralized SCADA

architecture. However, InGen found the T-BOX webserver to

be ideal for local diagnostic and troubleshooting tools used by

EWSU’s technicians.

For upgrades at the lift stations, InGen provided panels that include a T-Box MS

RTU, LCD flat screen monitor and indicator panel. The RTU monitors and controls

operation of pumps, valves and wet well level and includes safety/security monitoring

functions such as door intrusion and smoke detection.

SCADA communications are via the Motorola Canopy wireless network with 900

MHz subscriber module radios installed in the panels. Over the network, operators have

access to alarms, live status for all points at the stations and historical information.

Using Semaphore’s TWinSoft programming environment,

InGen developed standard function blocks for pump station

operations. Use of the function blocks maximizes commonality

among the stations and simplifies operations and maintenance.

Using T-BOX MS RTUs, InGen implemented monitoring

and automation for all filtration plant processes including filter

backwash sequencing, low service pumps, high service pumps,

alum treatment, carbon slurry treatment, caustic soda treatment,

fluoride treatment and water storage tanks

Like the lift stations, filter backwash and other processes

were suitable for InGen’s development of standard function

blocks. This significantly decreased process testing and startup

and also simplifies operations and maintenance for EWSU.

InGen’s implementation for EWSU was able to take full advantage of many of the

features offered by Semaphore’s T-Box products. These included alarm management

of all three processes, data logging to process and retain historical data in the event

of network downtime, push technology and multi-communications, an integral web-

server and the TWinSoft programming environment.

Application FeatureSCADA

Advancements in products that leverage converging

technologies have created significant opportunities

throughout the power systems industry. With communi-

cations-related advancements, the right choice of solu-

tions can extend return on investment (ROI) via expand-

ed power system benefits. Such has been the case at

Dairyland Power Cooperative (DPC), head-quartered in

La Crosse, Wisconsin.

In 2004 DPC, a 1,000 MW generation and transmis-

sion cooperative, was experiencing diminished service

within its analog cellular-based data communications

system, with the possibility of no further service beyond

February 2008.

DPC provides power for 25 member cooperatives and

20 municipalities who serve over 500,000 customers. A

Touchstone Energy affiliate, DPC’s service area encom-

passes 62 counties in four states (Wisconsin, Minnesota,

Iowa, and Illinois). The cooperative owns and operates

more than 3,100 miles of transmission lines and 348 sub-

stations. The cooperative produces electric power from a

variety of sources including hydro and coal-fired plants

plus renewable resources, such as landfill methane

recovery and animal waste-to-energy.

“With the imminent need to replace the old cell phone

system, there was an opportunity to install a new auto-

mated telecommunications system that would provide

secure collection of meter readings from all of our sub-

stations,” said Ed West, director of Telecommunications

and Control at DPC. “At the same time, we wanted the

same system to provide real-time meter data, local

alarms, and a secure communications path for our AMR

(automatic meter reading) members.”

The DPC staff identified a list of required capabilities

for a secure communications path including:

• Substation automation information from the

substation to the DPC office

• Real-time meter data for display on a Security

System Operations (SSO) website

• Substation kWh meter readings every 15 minutes for

billing purposes

• Automatic Meter Reading (AMR) data from the

substation to the distribution cooperative office

• One system that could support the needs of both the

member utilities and DPC for secure, robust, wide

area communications

In order to simplify new equipment installation in each

distribution substation and minimize the amount of train-

ing required, DPC staff made decisions early in the

design process including:

• Each distribution substation would have a standard

set of equipment

• The communications cabinet would have a custom

designed enclosure

• The communications cabinet components would be

assembled in the DPC facility

• The spread-spectrum radio, router, communications,

protocol interface device, and high-end multifunction

meter would be tested and verified by the DPC meter lab

• Remote facility monitoring would be provided with

physical and cyber-security

• A 48 VDC battery-backed power supply must be

included for all equipment

• The cabinet design must allow for modular

expansion to meet the requirements of each substation

• Each completed cabinet would be taken to the

substation to be installed and field verified

In December 2004, a comprehensive plan was

approved for the installation of an upgraded distribution

automation/telecommunications system to accomplish

these goals. The project included th expansion of the

existing digital microwave network, installation of

point-to-point, IP-capable spread-spectrum radios and

installation of a custom-designed metering and com-

munications cabinet to provide secure serial and IP

connections for real-time billing metering data, histor-

ical data, distribution SCADA, load management and

AMR traffic.

Because metering was a primary goal of the project,

Dairyland Power decided to evaluate a multifunctional

digital meter from Schweitzer Engineering

Laboratories, Inc. (SEL). “We had used a number of

SEL relays and other protection products over the

years and felt very confident about their quality,” West

said. “Plus, we wanted to integrate the metering equip-

ment into a highly customized communications sys-

tem, so the product features and level of SEL technical

support were also important to us.”

The SEL-734 Revenue Metering System, which

DPC considered for the project, offers complete instan-

taneous metering functionalities including voltages,

currents, power, energy and power factor. Other capa-

bilities, such as predictive demand, time-of-use meter-

ing, automatic voltage sag/swell monitoring, harmonics

metering, and synchrophasor measurement, make this

meter an exceptionally versatile system component.

“From a metering perspective, Dairyland Power

wanted to do daily load profile and interval-by-interval

metering of their delivery points for billing purposes,”

said Dick Martin, product manager of SEL’s Meter

Systems Division. “They also wanted to provide real-

time monitoring of energy, the amount of power being

delivered, for both generation and trans-mission purpos-

es and to make that information available on a distribu-

tion SCADA system to their members. As a multifunc-

tion device, the SEL-734 Revenue Meter is very well

suited to all of those needs.”

Billing data are collected from the meters by a master

station system running Itron’s latest MV-90xi meter-

reading software, which has the ability to query devices

over a wide area network (WAN). At the same time, via

the meter’s DNP3 protocol capability, Dairy-land is

using its distribution SCADA system to poll the meters

for real-time operational data.

Otherwise, this remote function would typically be

done by installing RTUs costing $3,000 to $5,000 (for

models suitable for this application). “Historically, the

sensors on RTUs required DC input,” said Martin. “That

usually meant incorporating AC-to-DC transducers that

require annual calibration, which can be a maintenance

nightmare. However, because the SEL-734 Revenue

Meter communicates via DNP3 protocol, it is compatible

with SCADA just as if it were an RTU, without the main-

tenance costs and headaches.”

“Another factor that drove the scheme was that the

meters Dairyland Power was using before had room for

improvement,” says Ken Graves, the utility’s Manager of

Telecommunications Services. “Based on Schweitzer’s

reputation, we felt confident that the SEL-734 Revenue

Meter would provide us with a good, workable solution.

Also, because we were fabricating our own panels, we

wanted a panel-mounted meter for our transmission envi-

ronment. The SEL-734 met our requirements nicely,

rather than the standard round, socket-based meter. So,

there was interest in the SEL-734 from the transmission

side of our business. Plus, using a high-end, panel-

mounted meter allowed us to use the same meter to meet

our distribution metering needs.”

The SEL-734 Revenue Meter’s power quality moni-

toring capability is another feature that is significant to

DPC. The utility wants to make certain that the power it

delivers to customers is within its high-quality parame-

ters, and if there are any issues, they have the information

they need to quickly solve the problem.

“This metering device is very feature-rich for an

affordable price,” Martin said, “when you consider that

capabilities like power quality monitoring and instanta-

neous synchrophasor measurements are usually collected

with expensive single-purpose devices that can cost from

$25,000 to $50,000.”

“Dairyland Power selected the SEL-734 because it

provides very high-accuracy energy metering, load pro-

file data collection, instantaneous power measure-ments,

power quality monitoring, and communicates simultane-

ously over a modem, serial ports and wide area networks

(WAN),” Martin said. “The meter is backed with a ten-

year, no-questions-asked warranty and SEL’s network of

factory and field support engineers.”

Renewable energy is the way of the future. We already see hydro power towers on

river beds, wind farms on hillsides and solar panels on rooftops. Now Granger Electric

in Pennsylvania has perfected a way to produce biogas, or a gas fuel derived from the

decay of organic matter, by extracting methane from decomposing landfill waste and

supplying it to customers as an alternative greenhouse fuel.

Unharnessed, methane is one of the most potent greenhouse gases, and is 23 times

more potent than carbon dioxide. Granger’s Lancaster Landfill Gas Recovery Project

uses wells to both oxygenate the waste mass, expediting the decomposition process, and

to trap the raw biogas before it can escape into the atmosphere. Separators are then used

to clean the gas by extracting methane from the remaining gas substance (composed of

carbon dioxide and trace elements) for use

as a natural gas alternative.

The whole process creates a symbiot-

ic eco-relationship between waste and

energy by aiding in the waste degrada-

tion process, repurposing methane that

would have otherwise been emitted into

the atmosphere, providing a less expen-

sive form of energy to the world and by

providing an alternative to less eco-

friendly options.

Biogas DistributionOne of Granger’s biggest customers,

a major international food supplier,

located 13 miles away uses the green

energy as a natural gas substitute to

power the boilers that keep its entire

plant operating. Because the biogas

supplied by Granger is approximately half the cost of natural gas, the customer is able

to significantly decrease their power costs without much of an upfront investment. To

utilize Granger’s biogas product the customer had to customize their boiler system,

but that required little more than increasing pipe sizes and installing an alternate pip-

ing system to be used in lieu of their natural gas or fuel supply.

“It’s just another supply link that has to be put in and retrofitted into the existing

scheme of things. This cost is recouped quickly by the savings they receive from our

program,” said Joe DiFerdinando, electrical engineer, Granger Electric.

Monitoring ConsumptionThe plant is relatively large and spread out, with metering panels located throughout

the various buildings on site to track the amount of gas used. Inside each of the three pan-

els is a Rockwell Automation CompactLogix Ethernet Programmable Automation

Controllers (PAC), which monitor gas flow vari-

ables to measure consumption at the facility.

To connect Granger’s main facility to its cus-

tomers, a T1 hardwired phone line is used. The

next decision was how to link up the end of the

phone line at the customer site to the three PACs.

“Because the plants are so spread out, we opted

to use wireless at those points to save on installa-

tion. We just needed to find a product that is

robust and easy to implement,” said

DiFerdinando. ProSoft Technology’s water and

dust-tight 802.11abg

Industrial Hotspot

radios (RLX-IHW-

66) were selected.

“We use CAT-5

cable and Power over

Ethernet (PoE) for

both power supply to

the radio and commu-

nication between the

radio and the PAC.

PoE allows us to plug

the radios right into

our PACs, plus the

casing allows them to

be mounted outside

without weather con-

cerns,” said

DiFerdinando.

The Result: A Fully Automated SystemThe T1 connection links the plant back to a master PAC in Granger’s main plant,

which is constantly pulling meter data from the remote customer sites and feeding the

information up the chain to corporate for billing. The bandwidth allows them to see

things in real-time, and is entirely automated so there is no need to go onsite at the cus-

tomer’s facility to collect meter information.

“The radios are great. They saved us on installation and simplified implementation.

I would recommend them to anyone,” said DiFerdinando, “My ProSoft sales represen-

tative was incredibly helpful, involved in the process, and knowledgeable on the tech-

nology and application. He deserves kudos.”

BenefitsGranger is a carbon negative facility.

They convert their own product onsite

into electricity using an electrical gener-

ator to run their facility, so they are

entirely self-sustained. The balance of

remaining unused electricity is sold to

the local utilities company, reducing

dependency on fossil fuels.

The food manufacturers can feel good

too. By using repurposed methane, the

highly potent greenhouse gas was not

emitted into the atmosphere.

But that’s not all. “Landfill-gas-to-

energy is not just an environmentally

responsible choice, it makes sense finan-

cially. The savings we are able to offer

our customers can be enough to help companies stay in America,” said Joe

DiFerdinando. “Another one of our customers, one of the largest manufacturers of dis-

posable dishware, was able to save enough money using our natural gas substitute to

add a third shift during the week and schedule weekends into production. The extra

shifts mean extra jobs. It’s a nice feeling.”

Over the last 20 years, ProSoft Technology’s product lines have grown to over 400communication interface modules supporting more than 60 different protocols. ProSoftTechnology’s connectivity options enable controller platforms to provide solutions inareas such as computing gas flow calculations and SCADA telemetry applications. Thesolutions also enable interfacing to motor control, drives and other devices in indus-tries such as water/wastewater, power generation, oil & gas, machinery, packaging andproduction.

The four switches in the SF series come in both man-

aged (SF2 and SF3) and unmanaged (SF1 and SF4) ver-

sions, as well as in stand-alone or 19 inch rack mount-

able configurations. The managed switches support

power over Ethernet (PoE) on ports 0 and 1, can act as

power source equipment (PSE) or a powered device

(PD) and include an FPGA-based low power CPU that

integrates the management software.

All of the ports are individually configurable. For

managed switches, a service interface is accessible at the

front panel, providing an easy way to configure the

switch using an SMB interface on a standard D-Sub con-

nector. For the unmanaged switches, MEN Micro also

provides fixed managed versions with a configuration

EEPROM tailored to the application's requirements.

This may include features such as 802.1p priority and

plete RF modem in one small package, replacing tens of components compared to a dis-

crete design. No external components are required, except an antenna. The modules are

delivered on tape and reel for efficient volume production. Its small size and low power

consumption makes it well suited for integration into size constrained battery operated

equipment. The modules are based on a new very low cost platform, and have been

developed for volume applications with a price target of less than $10 at 50,000.

The ISM bands are used and shared by more and more applications, putting higher

demands on the co-existence of radio systems. Due to cost reasons ASK systems have

been preferred in the low cost segment, but these are more subject to interference. The

new RC11x0 series from Radiocrafts offers a solution based on FSK modulation, and

selectivity and blocking properties. By combining RF technology, and a streamlined

module assembly and test production line, the new module series offers a unique com-

bination of performance and price.

The RC1140 (433 MHz) and RC1180 (868 MHz) modules are pre-certified for oper-

ation under the European radio regulations for license-free use. When used with quar-

ter-wave antennas a line-of-sight range of 1200 and 600 meters, respectively, can be

achieved. The RC1190 (915 MHz) is designed for operation under the FCC regulations.

SEL Releases Spread Spectrum Radio Security SolutionSchweitzer Engineering Laboratories, Inc. (SEL) is offering a new security solution,

SEL-3031 serial radio transceiver with optional security card. The license-free, spread-

spectrum radio creates an easy and eco-

nomical communications link to access

challenging locations separated by 20

miles or more such as various industrial,

utility and commercial applications.

"This is the first radio I've seen that

addresses two significant needs in the

industry, cryptographic security and multiple

data ports, all in one radio," said SEL security product manager Dwight Anderson,

CISSP, GSEC. "Every day there is pressure to reduce costs, be more secure and do more

with less. Now SEL gives you the means to achieve these objectives."

SEL radio features include versatile, economical operation that combines three seri-

al data ports in one radio, allowing up to three different connections and protocols to

operate simultaneously. The radio transmits data in the license-free, 900 MHz ISM

band, providing an economical communications path or backup communications sys-

tem. The radio also protects critical data and prevents malicious attacks with session

authentication and strong 128-bit Advanced Encryption Standard (AES) encryption.

aggregate data rate on single or multiple serial data ports. The radio can operate in

extreme environments trouble free and offers multiple form factors and power supplies,

including wall mount, rack mount and an optional NEMA 3R enclosure to meet spe-

cific application requirements.

Digi Releases Mesh Networking Protocol OptimizedFor Battery Powered Networks

Digi International has introduced DigiMesh on 900 MHz and 2.4 GHz XBee embed-

ded RF modules. DigiMesh is a peer-to-peer mesh networking protocol optimized for

battery powered networks that simplifies mesh networks while providing features such

as sleeping routers and support for dense networks. It will be

offered in addition to existing XBee point-to-multipoint and

ZigBee mesh networking solutions as part of Digi's drop-in

networking product line.

DigiMesh is a peer-to-peer mesh protocol that can be

deployed on a variety of Digi products. In other mesh archi-

tectures, devices are often divided into a parent-child rela-

tionship of parent routers, which provide traffic cop func-

tions and end devices such as sensors. These routers often cannot be put into a sleeping

state and therefore must be plugged into a power source.

With DigiMesh there is no parent-child architecture. All devices can be put into a

sleeping state to conserve power and all can simultaneously be a router and end device.

This is especially critical for situations where sensors or devices being managed are far

from a sustainable power source and require the use of battery and/or power-harvesting

technology. This one device type architecture also simplifies application development

and deployment while improving scalability.

DigiMesh joins other XBee protocols including IEEE 802.15.4, the ZigBee-PRO

feature set and multiple proprietary long-range protocols. DigiMesh is currently avail-

able on extended-range 900 MHz and globally deployable 2.4 GHz XBee modules. It

will also be available across Digi's Drop-in Networking solutions, including XBee

adapters, network extenders and gateways in the fourth quarter of 2008. This product

extensibility allows customers to match the best hardware solution for their application

and empower it with DigiMesh networking functionality.

Connect One Releases Small andVersatile Embedded WiFi Module

Connect One has released the Nano WiReach, an

embedded WiFi bridge that quickly and easily connects

any embedded device to 802.11b/g wireless LANs with

minimal programming. Measuring 1.7 by 3.3 cm, the

Nano WiReach’s multiple hardware interfaces and exten-

sive firmware functionality make it an advanced

and versatile WiFi solution for embedded devices.

Based on Connect One’s iChipSec CO2144 IP

controller chip, Nano WiReach includes a full

suite of Internet protocols and applications,

enabling immediate and full–featured connectivi-

ty for embedded solutions without any WiFi driv-

er development or porting. The WiReach’s

firmware also supports several modes of operation

including Lan to WiFi bridge, serial to WiFi

bridge, full internet controller mode, embedded IP

routing and PPP emulation.

Nano WiReach includes RMII, USB, SPI and

fast UART interfaces for integration into existing

or new designs. It is available in two versions, one

with an antenna connector and one with a built-in

antenna. Nano WiReach offers an advanced level

of Internet security. It includes the latest WiFi

encryption algorithms, WPA/WPA2, in both PSK

and enterprise modes, and Internet SSL encryption algo-

rithms. In addition, it serves as an inherent firewall, pro-

tecting the embedded application from attacks originat-

ing from the Internet.

Nano WiReach effectively WiFi-enables devices that

use any kind of embedded real-time operating system.

Designers do not need to port/write WiFi drivers or sig-

nificantly reprogram their applications to connect to

WiFi using the Nano WiReach. In Internet Controller

mode, Nano WiReach is driven by simple text commands

and off loads the WiFi drivers, WPA supplicant, Internet

security, networking protocols, and all communication

tasks from the host microcontroller and application. This

offloading of communication tasks frees up host process-

ing bandwidth and simplifies the wireless design process.

Since Nano WiReach’s firmware is remotely updateable,

new security or connectivity protocols do not require

application redesign, increased memory, or faster proces-

sor speeds.

Nano WiReach supports 10 simultaneous TCP/UDP

sockets, two listening TCP sockets, SMTP, MIME,

POP3, FTP, Telnet and HTTP/HTTPS clients, an

HTTP/HTTPS embedded Web server with a website for

the host application and one for configuring the module.

Nano WiReach supports 64/128-bit WEP, WPA/WPA2

(PSK and Enterprise) encryption, AES-128/256, SHA-

128/192/256, 3DES; the SSL3/TLS1 protocol for a

secure client socket session and a secure FTP session.

Carlson Wireless Rolls Out theSafeTCOM Wireless PBX/PA System

Carlson Wireless has added the SafeTCOM wireless

PBX/PA system to

its existing line of

fixed wireless

solutions. The

SafeTCOM is a

point to multipoint

digital microwave radio system designed for outdoor

industrial facility and campus public safety applications

that require both fixed phone and PA services. The sys-

tem is available in unlicensed frequencies 2.4, 5.4 and 5.8

GHz as well as the licensed public safety 4.9 GHz fre-

quency with a range of up to 30 miles.

The SafeTCOM radio system includes a single base

station with up to 16 CO lines and 20 field systems

(CPEs) each equipped with up to two phone

(fax/modem) lines and an amplified public address out-

put. Carlson’s TrueTDM plus IP technology assures car-

rier class quality and complete interoperability with VoIP

and legacy TDM systems while also meeting all 911

compatibility requirements. In addition, SafeTCOM can

be configured so that system managers can reliably mon-

itor the system remotely or locally with a Network

Management System.

The SafeTCOM wireless PBX/PA maintains Carlson

Wireless’ standard of easy set up, reliability and low cost.

The radio card, the multiplexer, CPU and network inter-

face card are all fully integrated into the CPEs and the

base station card cage. This saves customers thousands

on labor and material costs associated with typical wired

PBX and PA systems.”

Because the SafeTCOM was designed for remote

communications, units require minimal operating power

and also accept any DC voltage from 12 V to 24 V. Solar

power kits with up to seven days of backup power are

also available.

Ernest Zingleman, Business Development Executive FreeWave Technologies

In this article, examples of systems and equipment

used in oil and gas production fields are referenced.

However, the ideas and implementations described here-

in can easily be applied to water and waste water sys-

tems, electrical grid control and monitoring, or virtually

any field automation project.

As the automation of field processes advances as a

result of new technologies, the human imagination con-

tinues to find new ways to use this technology and push

technology providers for more powerful tools. Fifteen

years ago, even the more advanced automation systems

seldom had telemetry, and if they did, the data throughput

was extremely low and seldom provided coverage to all

remote sites. The usefulness of the technology was limit-

ed when only some sites could be remotely monitored.

With the many new telemetry technologies available

today, it is common to have 100 percent communication

to all field locations and achieve data throughput from

field sites of 9,600 bps or even 115.2 kbps. Additionally,

high speed backbone telemetry is now available in the

megabits per second range.

A recent trend is “wireless instrumentation,” or the

collection of analog and digital signals by an RTU

(remote terminal unit) PLC (programmable logic con-

troller) or EFM (electronic flow meter) from remote

equipment and sensors without the constraints of hard-

wiring. These signals may indicate or provide for pres-

sure and temperature, plunger arrival, remote wireless

valve control, switch closures, emergency shut down, or

status change. Processes that until recently had to be

hard-wired can now be done wirelessly with radio.

However, the very latest of these advances is the

“wireless network”, in which one radio system commu-

nicates from the desktop PC, through the RTU or PLC,

all the way to the to the field instrument (i.e. transducer,

sensor, valve, etc.) without any hard-wired connections.

This system operates all on one common radio network.

This allows the user to see the health and status of not

only the controllers at remote locations, but also of the

instrumentation attached to the controllers and the teleme-

try system. This diagnostics and troubleshooting capabil-

ity is available to the user throughout the entire SCADA

system, again available on one common radio network.

There are several manufacturers who make radios that

can retrieve data from remote locations. There are sever-

al manufacturers who make wireless I/O (Inputs and

Outputs), but only recently are there single radio solu-

tions that can offer both technologies in one common

communication network. These new wireless networks

are challenging the conventional thinking in automation.

The earlier school of thought was based on the idea

that the long haul for data from the remote site back to

the host could be reliably done by telemetry, but that the

local area connections to the instruments must be hard-

wired to ensure reliability. For several reasons, today’s

radio technology has been proven to be more secure and

reliable than the older hard-wired connections to sensors.

NetworksWhen most of us think of a network connection, we

envision a Cat 5 cable running through an office, con-

necting the various computers in the office to the server.

In field automation, there are two more types of net-

works. The first is the WAN (Wide Area Network), which

can be a very wide area, sometimes covering 40 to 100

miles. This is often referred to as the “backbone” or

“skeleton” of the radio network. The construction of this

backbone or WAN consists of a series of repeaters and

slave radios that connect the host computer to all of the

remote locations and field RTUs, PLCs or EFMs.

This repeater network, depending on which technolo-

gy is used, offers high speed throughput while also offer-

ing the ability to bridge many physical obstacles, such as

hills, valleys, forests and buildings. Repeaters allow the

system operator to cover distances far greater than any

single radio link alone can cover. A single radio link may

be only 20 to 30 miles, but by using multiple repeaters

the user can rebroadcast his data and regain full signal

strength at every repeater, thereby extending his network

to 100 plus miles if need be.

In some telemetry

technologies whether

using spread spectrum

radios or licensed

radios, the same radio

used in the RTUs can act

as both a slave to send

data back to the SCADA

host, and as a repeater to

other field devices, or

other RTUs. This func-

tionality is commonly

called “slave/repeater”

mode. This capability

allows the user to be

able to both expand his

network (WAN) almost

limitlessly by utilizing

his remote sites to act as

a series of repeaters,

and to use the radio in

the RTU to poll the instrumentation. This ability to poll

the instrumentation creates a second network of instru-

ments wirelessly reporting back to the RTU. This short-

haul network is the equivalent of a LAN (Local Area

Network). It may be easiest to think of all of the instru-

mentation on one well site such as casing or tubing

pressure, wirelessly talking to the RTU as the LAN, and

the various well sites talking back to the field office as

the WAN.

Now we have two interlacing networks in which the

WAN and the LAN are working on one radio system

and using a common connection. This common connec-

tion is the slave/master switchable functionality of the

single radio used in the RTU. The radio installed in the

RTU functions as both a slave to the SCADA host,

responding whenever the host requests data, and a mas-

ter to the wireless I/O when the RTU requests data from

the instruments.

EconomicsThe wireless I/O is less expensive than conventional

hard-wired systems and much easier to install. In a typi-

cal oil & gas well location, the operator will want to

bring measurements from multiple locations back to the

RTU or EFM. When a contractor (perhaps a licensed

electrician) is hired to install these hard-wired connec-

tions in field automation, the costs are about $16 per foot

(cost estimate derived from averaging prices from differ-

ent areas of the country). Costs remain similar whether

the install is direct burial cable or conduit and wire.

Using this cost as a reference, the break-even point for

wireless I/O then is around 50 feet and that is if we con-

sider only the cost of wire and labor. The cost savings are

far greater when there are two or more wire runs required

at the same remote site. This is because the only addi-

tional cost is for the second slave radio located at the

additional cluster of sensors. For example, an operator

wants to gather casing and tubing pressure from a well

head and also monitor tank levels at a different section of

the remote site. He can use the one radio already in the

RTU, and only one additional slave radio. He saves $16

a foot for both clusters of sensors.

Time is another factor in the true cost of installation.

Again, using the typical oil and gas well site as our exam-

ple, it is a full day’s work for a crew to install wire and

trenching for a well head to retrieve casing and tubing

pressure, plunger arrival and control lines for the valve.

Conversely, the wireless I/O radio can be installed in just

20 minutes. If the installation is done by the operator’s

personnel, the cost savings are two man-days per loca-

tion, assuming a two-man crew for one day to install with

hard wire.

One of the other intangible expenses associated with

installation is that it seems to be an unwritten law that

jobs can never be completed in one day. There are always

the scheduling conflicts and associated logistical prob-

lems of getting the contractors and end users on location

at the same time on the same day. Invariably, someone

always has to go back to the location and ensure that

everything is complete. With the 20 minute install of the

wireless I/O radio, one man can start and complete the

job rapidly and then move to his next assignment.

ReliabilityIt is common for people to question the reliability of

wireless products. As in all changes or paradigm shifts,

people take some time to adopt new ideas. Radio tech-

nology has proved itself in the oil & gas industry as a

reliable data highway for remote data collection from

RTUs and EFMs for more than 20 years. Now with the

new wireless I/O functionality of radio networks, the reli-

ability question again is a concern and stumbling block

for the advancement of this technology. Some wireless

I/O equipment providers have built safe guards into their

equipment and networks to address these concerns.

Examples include link alarms, command alarms and

autonomous collection mode:

FeatureNETWORKING

• Link alarms let the operator know if the signal

between the I/O slave and the RTU has been lost. The

operator then knows that he is no longer receiving data

from the instrument.

• Command alarms warn the operator that while the

link is still operational, the command to change (i.e. com-

mand to shut a valve) could not be executed. The reason

may be mechanical or electrical, but in either case, the

“need to know” is critical and the wireless I/O can sup-

ply this alarm.

• Autonomous mode means that if the RTU loses its

radio link to the SCADA (Supervisory Control And Data

Acquisition) software, hosts in the wireless I/O radio and

the radio in the RTU will continue to communicate. The

RTU is programmed to be the control on the location;

therefore if a tank reaches the high level mark, the RTU

will receive this information from the wireless I/O radio

and send the command to shut the valve to the tank.

Bear in mind, no system is completely immune to

signal loss. Wired systems are prone to having wires cut

when a new gathering line is laid, or a new control line

is installed after the original system is installed.

Moreover, with lengthy cables connecting equipment

and sensors, there is the very real threat of lightning

damaging expensive remote site equipment. Rust, cor-

rosion, steam, dirt, dust, and water can all affect a wired

instrumentation system. The difference is that while

wire cannot tell you if it has a problem, a radio can.

Wireless I/O can provide an alarm when the con-

nection is lost. This feature is operationalized as

a digital input at the RTU. Wireless I/O can also

provide command alarms as a digital input when

the radio cannot perform the function it was com-

manded to perform.

Power RequirementsWe have discussed the ability of some radios to

operate in slave/master mode, in which the LAN

and WAN networks use the radio in the RTU as the

common link between the two systems. While this

is an elegant way to operate when installing new

equipment, many end users and operators have

legacy systems using older technologies that do

not support this functionality. In these cases, it is

still a viable option to have two radio systems.

This can be done by using the legacy system as the

long haul (WAN) back to the host computer, and

then installing a new LAN radio system at the

wellhead to collect the local data wirelessly for the

RTU or EFM.

This second solution is still economically

superior to running conduit or trenching at dis-

tances over about 50 feet. The two radio solution

consumes more power at the RTU. Typically at

remote sites, this means larger batteries and larg-

er solar panels. On the slave side where the sen-

sors and instrumentation is located, the power

consumption remains constant. Many of the new wire-

less I/O radios draw as little as 6 mA of current when

being polled continuously, or six plus times per second.

Many of the newer pressure transducers are very low

power and also feature 1 to 5 volt output signals, while

also drawing only 7 mA per transducer. An example of

a typical well head gas field operation using wireless

I/O will look like this:

Two pressure transducers (one for casing and one

for tubing pressure) at 7 mA each equals 14 mA con-

tinuous draw. One wireless I/O radio has a 6 mA con-

tinuous current draw. Total current draw for data col-

lection and transmission for the RTU is 20 mA. If we

provide an 8 amp hour battery, this site will have 12

½ days of autonomy and the battery charge can be

maintained with a 2 Watt solar panel. Both the radio

and the battery can be housed in a 6 by 8 by 4 inch

NEMA-4 enclosure. The battery and solar panel

required can be sized according to the load that each

site will require. For example, if the operator only

wants one analog input, the power consumption drops

by 7 mA, or about 1/3 of the previous calculation. The

site can then be powered by a 5 amp hour battery with

about the same autonomy.

SummaryMany oil & gas companies are seeking to under-

stand the future of automation, and their decisions

today will affect them for years to come. BP, Chevron,

Dominion, Kerr McGee and others all have internal

focus groups whose objective is to provide “Best

Practices” and procedural guidelines. These steering

committees then provide guidance through the maze of

new products and technologies. Many companies are

also trying to achieve standardization in hardware and

software across their entire operation for ease of sup-

port and maintenance.

In the past, all gas flow and oil production data was

gathered by hand. Today, the collection of data from

instrumentation and transmission to a central location is

accepted as the new standard. The relevant question

today is not “should we automate?” but rather “which

types of automation will be a best fit for your operation?”

Before choosing an equipment or solution provider, oper-

ators need to ask themselves the following questions:

• Will this technology reduce expenses?

• Will this technology help optimize production by

giving us real time alarms and remote control of

our process?

• Will this technology save us man-power and time?

• Does this technology allow us to share data between

field offices and other locations?

• Is this technology affordable?

• Will this technology provider be here for the

long haul?

• Does the manufacturer support the end user before,

during, and after the sale?

• Does the factory have 24-hour telephone

technical support?

• Is local field support available?

• Is local or factory training for our personnel available

from the manufacturer?

• Are the time limits and limitations of the

manufacturer’s warranty acceptable?

With the emergence of robust wireless field automa-

tion, the end user can easily find manufacturers where the

answer to all of these questions is Yes.

Today’s spread spectrum and licensed radio technolo-

gies allow field operators to build WAN’s and LAN’s

comparable to what has been available in the office and

the wired world for several years. With the advent of

short range radios, wireless I/O radios, Ethernet radios,

GPS location device radios, and long haul data retrieval

radios all working together in one seamless network, the

future of field automation has never looked brighter.

In remote and rugged conditions, reliability of your com-munications system is paramount

Bob Gardner, Senior Product Manager Banner Engineering Corp.

Wireless technology was once limited by factors that

included inadequate bandwidth, early integrated circuit

design and insufficient power management technology.

Improvements to today’s wireless networks allow robust

monitoring and control, even in remote and harsh appli-

cations or classified areas.

Features such as bidirectional communications, fully-

acknowledged data transfer, and configurable default

output conditions make remote and field-based monitor-

ing and critical control a reality. Low power systems and

high-capacity battery packs now provide a lower cost and

more reliable solution than traditional solar panels. These

alternative power options have increased the usability of

sensor networks because the systems are no longer limit-

ed only to locations wired for power. New systems

enable cost-effective monitoring that is scalable down to

a single point.

Today, these improvements to RF technology make

wireless an ideal solution for a wide variety of applica-

tions such as field-based agribusiness and water manage-

ment systems, which use wireless networks to improve

water use, increase efficiencies and reduce manual meas-

urements. Process measurements such as operational sta-

tus, level, temperature and other crucial information can

now be easily monitored and controlled remotely, even in

locations not wired for data transfer or power.

Remote I/O Monitoring in the PastHistorically, wireless remote terminal unit (RTU) sys-

tems incorporated a number of different components,

including an RTU, radio, solar panel and rechargeable

battery pack, as well as input and output terminals. Once

all these devices were selected, users still had to purchase

an outdoor enclosure and integrate the disparate compo-

nents into a single, cohesive system. These older systems

were difficult to install in part because of the number of

components required to build the monitoring system.

Older monitoring systems were complicated to main-

tain over time. They frequently required large solar pan-

els and batteries to operate because of the diverse power

requirements of the components. These traditional moni-

toring systems were too expensive, or too large, for

small, single-point monitoring systems. To be cost effec-

tive, installing these systems required wiring as many I/O

points as possible back to each remote node. These local

wireless panels were relatively large and contained many

I/O points. Ironically, it required a significant amount of

conduit wire and time to connect a dozen or more I/O

points to the traditional large wireless RTU panel. Once

they were set up, the monitoring systems could not be

easily relocated to accommodate changes in the applica-

tion or the environment.

Remote I/O Monitoring TodayToday, many remote monitoring solutions are available

that offer more reliable wireless communication while

integrating many of these components into a single, inex-

pensive unit. A radio and I/O terminal contained within a

single housing that is rated for outdoor use eliminates the

need for an additional enclosure. Without this large, per-

manent enclosure, these new wireless industrial I/O

devices are easy to install, and then uninstall and move to

a new location as monitoring require-

ments change.

With the radio, power controller,

I/O terminals and RTU components

included within a single, water-resist-

ant housing, fewer mechanical and

wiring issues need to be incorporated

into a maintenance schedule, result-

ing in valuable time and cost savings

- without sacrificing capabilities. A

single wireless I/O device can collect

both digital and analog sensor read-

ings and forward this data to a central

collection point for analysis.

Evolution of RF Technology - Just as packaging

improvements have made wireless monitoring systems

easier to install, radio communication technologies

including Frequency Hopping Spread Spectrum (FHSS)

have improved network reliability. When using FHSS as

a communication method, the frequency range is split

into several channels. Data packets are transmitted using

these channels randomly in a pattern known only to the

master device, or gateway, and the nodes. If interference

is detected on one channel, both radios hop to the next

channel and resend the data packet, minimizing unsuc-

cessful transmissions in high interference environments.

Another method of ensuring successful data transmis-

sion is by using Time Division Multiple Access (TDMA),

which divides communication time into specific time

slots for each node and guarantees that all devices with-

in a radio network have time to transmit and receive data

packets. When multiple radios are not trying to commu-

nicate with the master device at the same time, data col-

lisions and radio interference are minimized. Using

TDMA to avoid data collisions also prevents wasted

power resources in resending data packets.

Bidirectional transceivers on both ends of a communi-

cations link ensure fully acknowledged data transmis-

sions. Polling and site survey capabilities monitor com-

munication integrity either at the radio master device

(gateway) or locally at each radio node. A site survey is a

signal strength analysis conducted by the gateway

to determine the reliability of the radio signal

received by the node. If a site survey is conducted

before installing the devices, the test ensures each

node is positioned at an optimal location.

Gateways poll their nodes at specific intervals

to verify the radio communications are operating.

If a gateway identifies a radio link that is not oper-

ational based on an unsuccessful poll, these new

systems are capable of reacting deterministically.

Deterministic response capabilities drive specific

outputs to a defined output state in the event of a

communications failure, ensuring control over the

network outputs and system responses.

For example, a remote monitoring system can

be used to monitor a tank level and control a valve

based on the level readings. When the radio signal

is disrupted, the valve may be automatically

closed to prevent equipment damage, and then

opened again when the radio communications

resume operation.

Power Management Systems - To accommodate

remote monitoring needs in locations without power,

optimized wireless I/O devices using advanced

power management technology can operate from a

single battery pack for several years. State-of-the-art

power management systems can now be configured

to extend battery life up to 10 years. This extended

life span is achieved by putting the entire system in

The Evolution of Wireless RTU Systems

Single Component

low-power mode. While in low-power mode, the wireless

device consumes almost no power.

The power management system can be configured to

periodically sample the sensor and report data at defined

intervals. These intervals can be configured from a few

samples per second to a few samples per hour with the

longer sampling intervals corresponding to longer battery

life. Often a five to ten year battery life can be achieved

by optimizing the sample and report rates.

Integrated power management systems are also bene-

ficial when using solar power. Typically, the entire solar

panel system can be significantly smaller, less expensive

and easier to install. With power options that include

solar panels or battery packs, radio devices can now be

installed over a wide geographical area, extending the

range of data collection for miles.

A growing class of power-managed sensors, including

temperature, relative humidity, ultrasonic and sub-

mersible pressure sensors take advantage of independent

power sources to operate for years without replacing bat-

teries. These flexible devices can even operate using line

power in ideal conditions and then operate from a battery

module if the line power fails, preventing costly crop or

product losses during unplanned power failures.

Cost Effective Scalability - Now multiple sensors can

be connected to a single radio node and dozens of radio

nodes can exist within a single radio network. Hundreds

of sensor readings can be aggregated into a single gate-

way device before being forwarded to a host-controlled

system for analysis.

Further extending this wireless I/O network are serial

data radios—backhaul devices that receive serial data

from another serial data radio, or a serial connection to a

gateway, and forward the data to another serial device

miles away. Chaining data radios can expand this net-

work indefinitely.

This backhaul architecture enables limitless scaling

for everything from single-point data collection to

10,000 data point applications while retaining the cost

advantage associated with minimal wiring for power or

I/O transmission.

New wireless technology enables remote monitoring

solutions that were previously unaffordable or impracti-

cal to install. Compact, reliable, inexpensive wireless I/O

monitoring devices can now be installed in isolated, low-

signal count locations for data collection. These

same compact devices can be easily relocated as

the application environment changes in what is

known as a peel-n-stick installation process.

Applying Wireless Improvements for Remote Monitoring

The new generation of wireless remote I/O

monitoring is particularly suitable for small, sin-

gle-point measurements, such as tank level moni-

toring in isolated locations. While previous

remote monitoring technology was too expensive

or too bulky to use for low-signal count applica-

tions, current technology makes these applica-

tions easy to install and use.

For example, a single wireless I/O device and power-

optimized ultrasonic sensor can reliably monitor tank

levels and report analog or digital inputs back to a central

location. The peel-n-stick installation allows this device

to be easily moved and reinstalled depending on the

requirements of the application.

Because these devices are more compact than past sys-

tems and are certified for a wide variety of environments,

they are easy to retrofit into existing applications, partic-

ularly on mobile assets such as trucks or boats that must

enter and exit hazardous locations or areas rated to

require intrinsically safe equipment. These devices can

be installed in a broad range of environmental conditions

ranging from outdoor installations exposed to weather to

applications within hazardous or explosive locations.

In agribusiness, the most common reasons for adopt-

ing wireless monitoring systems are improving crop

quality and reducing labor costs. Tasks that previously

required constant human intervention can be replaced by

installations of solar or battery powered sensors, nodes

and gateways. The most common use for wireless sensor

networks is the monitoring of soil moisture levels to con-

trol irrigation systems. As more land is used for agricul-

ture, water conservation will play a vital role in crop

quality and profitability.

For these applications, remote sensors can be used to

monitor and report the moisture levels of the soil back to

a central control location, notifying personnel that irriga-

tion is required before crops are damaged. With this con-

stant automatic monitoring, wasted water is minimized

without harming the crops.

To this end, vineyards are adopting wireless technol-

ogy for a range of tasks that include monitoring envi-

ronmental conditions such as soil moisture and pH lev-

els in the fields, controlling the dispensing of fertilizers

and insecticides, and detecting pests or mold. In the pro-

cessing facilities, wireless sensor networks are used to

gather tank level data, control flow of liquids, and ana-

lyze the relative humidity and temperature within the

storage rooms.

Drip, flood, and center arm pivot irrigation systems

are all suitable applications for wireless control and mon-

itoring. Wireless nodes using pressure and flow sensors

monitor the irrigation system and transmit data back to

the gateway or control center. These wireless systems can

notify personnel immediately when a component fails or

when the irrigation system fails to meet established per-

formance parameters, preventing crop damage or loss.

A single battery-powered node using a temperature

and relative humidity sensor can reliably monitor envi-

ronmental data within a greenhouse for years and trans-

mit that data back to a central control system. Once the

control system has calculated the corrective action, a

wireless signal sent back to the node can turn on fans,

open vents, cycle on heaters or coolers, or trigger a water

misting system.

ConclusionWhether your application needs to be a cost-effective

solution for single-point monitoring or scalable up to

10,000 data points, the new generation of wireless prod-

ucts and sensors offer reduced installation time, multi-

year battery life, reliable radio communications and sim-

ple integration into existing systems. These new systems

offer a simple solution to increase productivity and

reduce labor costs without sacrificing ease of use.

James Mustarde, Director of Marketing Twisted Pair Solutions, Inc.

Owners and managers of remotely operated sites face

significant challenges as they deal with new economic

pressures to improve the efficiency of field teams and

reduce technology expenditure. One technology area that

can be notoriously expensive and create barriers to pro-

ductivity is disjointed communications systems. In this

article, we’ll take a look how organizations operating dis-

parate facilities can put their communications systems

under the microscope to develop quick and easy strate-

gies for both “trimming the fat” and improving the effi-

ciency of today’s increasingly lean work teams.

To understand the state of communications in today’s

remote facilities, we must take a look at what types of

technology have been deployed, why and what problems

it may be solving and/or creating. Typically, remote sites

have deployed communications devices to meet specific

worker and departmental needs. For example, it might be

appropriate to have workers in a corporate office use IP

phones and mobile devices, while it makes more sense

for workers at a remote location to leverage land and

mobile radios (LMRs). These communications systems

work fine, as long as communications remain within a

specific silo (i.e., IP phone users communicate with other

IP phone users). However, if communications require

contacting a worker outside of that silo (i.e., an IP phone

user contacting an LMR user) significant roadblocks to

productivity, efficiency and collaboration arise.

The root cause of these roadblocks is simple, most

communications devices aren’t exactly good communi-

cators and they are unable to talk directly to other brands

or types of equipment. This issue can become increas-

ingly complex for growing and aging businesses since

their communications assets can vary greatly from per-

sonal computers (PCs), telephones (analog, digital or IP)

and handheld radios to PDAs and overhead paging sys-

tems, all from a variety of hardware manufacturers. As a

result, businesses with this type of a mixed infrastructure

have ultimately reached a breaking point. Either a)

acknowledge that certain workers will never interconnect

(a tough concept to swallow given the expense of today’s

most popular systems) or b) look for a better option that

incorporates all of your devices now and whatever you

may add in the future.

Demanding Better OptionsWhile many businesses choose to suffer in silence

with the limitations of their existing communications

infrastructures, others are demanding interoperability.

Unfortunately, companies in this position oftentimes fall

victim to the marketing messages of proprietary hard-

ware providers, which promise interoperability via a “rip

and replace” approach. Under this strategy, a company

would rip out everything they’ve got and replace it with

all new equipment from a single manufacturer, and then

magically everything interoperates. This approach is

based on the misleading idea that hardware brand stan-

dardization equals interoperability.

Brand standardization forces organizations to make a

number of poor and costly decisions, from retiring work-

ing equipment to pre-determining what can and cannot

be deployed in the future. It’s important to note that these

types of homogenous systems only operate with them-

selves, and aren’t truly capable of connecting an unlimit-

ed number of users on an unlimited number and type

of devices, networks or applications. Until organiza-

tions recognize brand standardization is not a long

term solution to interoperability, they will continue to

be hung up with silos of communication that harm

worker productivity, efficiency, collaboration and in

some cases, even safety.

Faced with physical, technological or financial bar-

riers, many organizations have begun demanding an

alternative solution that can seamlessly connect

workers using existing equipment, including propri-

etary hardware, into fully interoperable communica-

tions systems. To meet this demand, software-based

solutions (which do not require any investment in

new hardware) have emerged to break down walls of

incompatibility and connect workers using an unlim-

ited number and selection of communications

devices. With this breakthrough approach, organiza-

tions don’t need to perform a costly forklift replace-

ment of radio systems in order to achieve true com-

munications interoperability.

Software Raises the CommunicationsPerformance Bar

The availability of interoperability software, inde-

pendent of proprietary platforms, has forever changed

this market landscape. Now, organizations can seam-

lessly connect workers cross-site and across varying

communications systems, while leveraging existing

infrastructure and without deploying any additional hard-

ware. After demonstrating these significant advantages

over hardware, software has emerged as the only sensible

path to achieving communications interoperability. While

hardware industry stakeholders are doing their best to

position hardware at the top of the “software vs. hard-

ware” debate, organizations are learning the truth about

the fundamental building blocks of interoperability.

To take full advantage of the opportunities surround-

ing communications interoperability, it’s important to

understand the difference between operability and inter-

operability. Operability encompasses all of the necessary

equipment choices a company must make to meet busi-

ness requirements. For example, if an organization wants

to issue IP phones to all headquarters-based workers and

mobile phones to all field workers, it must acquire and

deploy that equipment. This type of operability must not

be mistaken for interoperability – the practice of seam-

lessly connecting those disparate devices with absolutely

zero limitations. While operability decisions can vary,

only software delivers the standards-based interoperabil-

ity businesses require.

Communications interoperability software connects

disparate devices (radios, telephones, mobile phones,

etc.) by converting the signals into group-level IP pack-

ets that are then transported across an IP network to other

devices and users. Once voice traffic is on the network,

communication sessions are subject to management and

security controls, and may be bridged, recorded, joined

into conferences or routed to devices outside of the sys-

tem. In addition, the status, presence and adaptive trans-

port network management provides for rich collaboration

among participating departments within an organization.

And careful use of IP multicast, QoS and transcoding

technology minimizes network bandwidth requirements.

The result is that groups of workers can talk and share

real-time data, with full control, regardless of the devices

or systems used. Moreover, with audio data converted

into IP packets and streamed across the network, a new

set of devices can directly link together and participate

simply and easily in communications.

With this type of advanced software technology, com-

munications interoperability is not limited to specific

devices. Using industry standard IP networks as the uni-

fying medium, a multitude of traditionally disparate

communications systems such as traditional analog

phone systems, new IP phone systems, PCs, PDAs, push-

to-talk (PTT) radios, LMRs and industry-specific propri-

etary devices can all interoperate in a seamless manner.

Real-World Case StudiesGiven the multitude of advantages associated with soft-

ware interoperability solutions, including the capability of

scaling to meet the needs of geographically disperse work

teams, these solutions have gained widespread use within

a broad range of markets, including oil and gas, utilities,

transportation facilities and others.

In the public utilities sector, communications interoper-

ability has become a major focus. Today’s utility organiza-

tions face a number of real threats to service continuity,

some natural and others man-made. While it’s been proven

that seamless communications is the backbone of every

utility emergency, many companies are still suffering from

debilitating interoperability and survivability issues that

unnecessarily leave workers, partner companies and pay-

ing customers in the dark. In the event of a storm, accident,

terrorist attack or other disaster causing an outage, utility

employees must be able to reach other internal response

groups and managers as well as relevant third parties, such

as fire and police departments.

largest utility providers in North America – delivering gas

and electric power to more than 15 million people

throughout northern and central California – recently

made the decision to tackle its lack of communications

interoperability as part of its ongoing investment in busi-

ness continuity and emergency response systems.

PG&E, like many utility companies, has a communica-

tions infrastructure using both trunk and conventional

radio mixed with cellular and push-to-talk services. While

these services are widely deployed, they often still don’t

provide full geographic coverage. And if a costly rip and

replace is not feasible, then utility companies are in a

quandary about how to support their operations and emer-

gency response teams in future years. The solution for

PG&E, built on open standards, enables the company to

continue to use its existing systems, hardware

infrastructure and end-user devices. This type of

instant, large-scale communications infrastructure

is essential to restoring service more quickly, not to

mention increasing customer satisfaction levels

and profitability.

The transportation industry is also quickly

adopting similar software solutions. Airport crash

phones, which are critical for response coordina-

tion in an emergency, typically rely on an anti-

quated collection of analog hardware, making

them costly to maintain, impossible to expand and prone

to frequent system failure – all problems routinely faced

by Sanford Airport Authority. The airport needed a new

solution that offered near-infallible reliability, cost-effec-

tive management, maintenance and expansion, and that

allowed for rapid deployment – a solution it found with

new interoperability software.

Similarly, Mumbai International, India's busiest air-

port, recently began a major infrastructure overhaul that

will provide extensive network coverage throughout the

airport’s terminal buildings and outside maintenance

areas. The airport plans to consolidate the majority of its

data, telephony and video systems onto a converged

wired and wireless IP-based network. As part of this

upgrade, Mumbai International airport is utilizing a soft-

ware-based technology to turn their IP phones deployed

throughout the airport into PTT radios. By removing dis-

parate technology barriers and allowing real-time inter-

action between radio systems and telephones, Mumbai

International airport can apply new working practices to

improve business efficiency and provide a better travel-

ing experience for passengers.

SidebarFour significant advantages, including flexi-

bility, innovation, reliability and cost savings,

have emerged in the software vs. hardware

debate to solidify software as the best approach

to enabling communications interoperability.

Flexibility – Interoperability software

leverages a standards-based approach to deliv-

er the widest possible breadth of deployment

options, suitable for even the most demanding

environments. Proprietary hardware deploy-

ments lock businesses into a single framework,

an unnecessary limitation for any organization.

Innovation – Software can be uniquely

paired with an SDK to enable the customiza-

tions organizations need to meet unique

requirements today, while providing open

options for the future. This type of sustainable

core architecture is an innovation simply not

inherent in yesterday’s hardware-based propri-

etary platforms.

Reliability – The unique distributed com-

puting capabilities of software promise contin-

uous, uninterrupted communications regard-

less of device, network or operator failure – an

essential reliability feature not included in

hardware-based systems.

Cost-advantage – Most importantly, soft-

ware can support industry standard off-the-

shelf hardware, minimizing upfront invest-

ments and reducing ongoing operational and

maintenance costs compared to proprietary

hardware solutions.

As demonstrated above, new advances in

software – built on open standards – are helping

organizations of all sizes, and across all dis-

tances, achieve communications interoperabili-

ty using their existing systems, hardware infra-

structure and end-user devices. As a result,

interoperability software has emerged as a far

superior offering than the market’s earlier, hard-

ware-based approaches, which typically

required a costly overhaul of existing infrastruc-

ture. Furthermore, during this tough economic

time, new practices and policies are being built

around wider, more open communications to

improve the flow of information, lower operat-

ing costs, and offer an easier upgrade path.

SFC Smart Fuel Cell IntroducesEFOY Pro Series for Reliable PowerIn Security Applications

SFC Smart Fuel Cell AG has released its new EFOY

Pro series for quiet, reliable power in remote security

and data transmission

applications. The

EFOY Pro series

delivers logistical and

cost-saving advan-

tages over convention-

al remote power sup-

plies, such as batter-

ies, solar cells and

generators. For exam-

ple, a concealed 25 W

camera requires a capacity of 600 watt hours per day and

these conventional systems have significant drawbacks

for such an application, especially risk of detection.

Batteries require frequent replacement that adds mainte-

nance costs and risks exposing surveillance systems.

Solar-power modules both stand out in many settings

and may be inoperable in bad weather, and generators

not only require regular maintenance such as refueling,

but they also are noisy and produce exhaust.

The EFOY Pro series supplies 24/7 maintenance-free,

odor-free and, most of all, quiet off-grid power for a vir-

tually unlimited period of time, as long as there is fuel.

The company’s 28-litre M28 methanol fuel cartridge, for

example, provides 31.1 kWh of power. That is enough to

operate a concealed, 25 W surveillance camera for more

than 50 days without any user intervention.

With its integrated set of connectors, the new EFOY

Pro series offers installation flexibility and can be

included in any customer application. The fuel cells’

casing and construction can withstand the roughest envi-

ronmental conditions and temperatures between -2°F

(–20°C) and 113° F (45°C). The fuel cell can be con-

nected to either 12 V or 24 V batteries, as the integrated

automatic charge control will recognize the battery type

and adjust the charge process automatically.

EFOY Pro series fuel cells can be connected to all

EFOY fuel cartridges, enabling the user to adjust weight

or operating times to the individual requirement of each

specific application. All EFOY Pro series fuel cells can

be combined with other power sources. In these hybrid

systems, the fuel cell switches on only when additional

power is needed.

The EFOY Pro series is available in three models:

EFOY Pro 600, EFOY Pro 1200 and EFOY Pro 1600.

The series offers a charging capacity of 600 to 1600 Wh

per day, depending on the individual application. In

operation, the EFOY Pro produces a very low humming

sound of 23 dB(A) at a distance of 23 feet (7 meters). It

can be operated in closed rooms and vehicles and will

produce off-grid power for weeks without requiring any

user intervention. Moreover, customers can remotely

monitor and control their security equipment with a

mobile phone or computer via an integrated user inter-

face. With all these features, use of the new EFOY Pro

series fuel cells will reduce customers’ personnel and

logistics costs.

Measuring 17 by 7.5 by 11 inches and weighing

approximately 18 lbs (8 kg), the EFOY Pro series fuel cell

fits into any switch cabinet or vehicle. For reliable out-

door operation in any weather, SFC offers the EFOY

ProCube. The weatherproof box features preinstalled con-

nectors and cables for any battery and fuel cartridge size.

Saft Develops New Tel.X Battery Saft has developed its new Tel.X battery, the first

high-volumic energy density, long-life, maintenance-

free nickel-cadmium (Ni-Cd) battery designed specifi-

cally to ensure maximum reliability and optimum total

cost of ownership for telecom equipment installed in

outside plant cabinets.

Over the last 10 years, telephony platforms have

evolved to include added services like data and video.

Maintaining the traditional POTS (plain old telephone

service) while adding these other services has signifi-

cantly increased the power demanded by equip-

ment installed in outside plant cabinets. In turn,

there is a greater need for stored energy for back-

up power to maintain the same runtime as before,

typically eight hours.

However, the battery compartments in these

cabinets have not grown in size in proportion with

the growth in telephony loads. In other words,

only the same volume is available to accommo-

date capacity requirements that are now signifi-

cantly greater. To compensate for this change in

requirements, the runtime must decrease, non-

essential loads must shed during a power outage,

the amount of stored capacity must increase or

some combination of all of these things. Currently,

increasing the stored capacity seems like the pru-

dent approach. This puts the burden directly on the

battery designers and manufacturers.

The new Link UPS outdoor backup power system is specifically

designed to provide both primary and uninterrupted, reliable stand-

by power for critical SCADA, telemetry, flow monitoring, natural

gas automation and critical surveillance equipment in harsh envi-

ronmental applications.

The durable NEMA 3R weatherproof enclosure has ample room for

drop-in installation of radio gear and RTU/control equipment on pre-

drilled brackets and DIN rails. The LinkUPS system contains environ-

mentally hardened AC-DC power circuitry rated for long life in freez-

ing and sun-baked environments. Temperature-compensated charge

voltage ensures that backup batteries are ready when AC power fails

and provides a minimum of eight hours of backup for loads up to 100

watts at 12, 24, 48 VDC or 120 VAC.

Tessco has made specification and product selection easy. Simply select by radio

model and these units ship complete with batteries, local and diagnos-

tic remote alarms and low-voltage disconnect, making installation fast.

Plug and Play LinkUPS products support GE MDS, Phoenix

Contact, Freewave, Control Microsystems, Allen Bradley and many

other equipment manufacturers. The unit features separate removable

backplane for easy equipment integration inside the cabinet, an oper-

ating temperature range of -20˚C to 60˚C, an auto-ranging input of 85

VAC to 264 VAC and 12, 24 or 120 VAC output options available. The

batteries are protected by a special compartment and pre-installed DIN

rails for easy equipment mounting.

Additional features for the LinkUPS include a built-in remote mon-

itoring circuitry with LED indicators, availability in 50 W and 100 W

sizes, double-V clamp pole-mounting hardware, deep cycle gel batteries

and a minimum backup time of eight hours.

Tessco Launches New Outdoor UPS System for Wireless Networks

Field experience with the NCX design was com-

bined with the current requirements of outside plant

applications and a set of design specifications were

developed for the new Tel.X battery. The main objec-

tive was to put at least 40 percent more battery capaci-

ty into the same cabinet compartment. This also had to

be accomplished while maintaining all of the other

proven advantages of Ni-Cd, such as long-life, reliabil-

ity and resistance to abuse. The evolution also aimed to

make the new battery maintenance-free, fast to install

and improve its compatibility with GR-3108 Class 3

requirements where the dirtiest, wettest and most

extreme temperatures are expected.

Because of this the Tel.X battery offers high-volumic

energy density of up to 100 Wh/L while weighing

around 30 percent less than a conventional battery. It is

designed for use in standard 19 and 23 inch racks and

cabinets, where its compact size makes it easy to fit and

install as a direct replacement for VRLA batteries, a typ-

ical installation time for a 48 V battery is just 15 minutes

and is compatible with all telecoms rectifiers.

Another key feature of the Tel.X is its long service

life, more than 20 years in normal temperatures and

more than 14 years at 40°C. In many cases the battery

can be expected to outlive the installation, during which

time it will be maintenance-free, under normal operating

conditions, with no need for topping-off with water.

The Tel.X battery design has been certified for com-

pliance to NEBS Level 3, which is the world’s highest

safety level for telecom equipment. Furthermore, the

Tel.X delivers predictable performance over a wide tem-

perature range, from -20°C to 40°C, and can withstand

extremes of -50°C to 70°C. This is particularly impor-

tant as the majority of cabinet installations will not offer

a temperature-controlled environment.

The Eaton 5130 UPS Solves PowerProblems for IT andTelecommunication Systems

Eaton Corp. has introduced its Eaton 5130 uninter-

ruptible power system. Part of the Powerware

series, the 1,250 to 3,000 VA line-interactive mod-

els are specifically suited for protecting servers,

routers, switches, workstations, as well as Voice

over Internet Protocol (VoIP) and

EDGE/3G/WiMAX wireless networking equip-

ment against power fluctuations and outages.

Available in slim 2U and 3U rack and tower

configurations, the 5130’s compact size is well

suited for dense rack enclosures. In addition, user-

replaceable hot swappable batteries allow users to

safely install new batteries without powering

down the connected equipment or removing the

UPS from the network rack. For applications

requiring longer run times, slim 2U external bat-

tery modules can be quickly added to provide

hours of backup time – especially important for

telecommunication systems.

“The 5130 family delivers features one would

normally find in more expensive systems,” said

Hervé Tardy, vice president and general manager,

Eaton’s Distributed Power Quality Business Unit.

“Customers will appreciate the UPSs’ comprehen-

sive functionality including load segment control,

multiple communication options, high output

power factor and high power density all in a sleek

affordable package.”

The high-efficiency design allows the UPS to

operate at 94 percent efficiency, reducing heat and

expensive cooling costs. And, with a 0.9 power

factor, the UPS delivers more wattage in less space to

protect more equipment and leave more room to expand

IT systems.

For control and management the 5130 features

Eaton’s LanSafe software, which provides visibility

over all of the UPSs using an intuitive graphical inter-

face and SNMP. Additional status information can be

seen on the LEDs front panel that gives users a quick

read of UPS status including low battery, overloads and

other important system information. Additionally, a

built in USB and RS232 serial ports, plus a slot to

accommodate a communications card, supports Web,

SNMP Modbus or serial communications.

Other important features include independently con-

trol output receptacles to selectively shed loads during

an outage, remotely reboot systems or manage sequen-

tial start-ups. 5130 options are extended battery mod-

ules, Web/SMNP cards, a how swap maintenance bypass

switch, rackmount PDUs and extended warranty plans.

New 800 kW Unit from CumminsOffers Better Fuel Efficiency and aSmaller Footprint

A new 800 kW trailer-mounted diesel generator set

from Cummins Power Generation provides a cleaner, qui-

eter and compact system

configured especially for

customers seeking mobile

power. The unit addresses

loads between 500 kW to

1,000 kW in a very cost-

effective manner.

Other features of the

new system include higher fuel storage safety with a 110

percent fluid containment system and improved emis-

sions, with the new 800 kW meeting Tier 2 emissions

requirements. A robust cooling system also allows the

unit to operate in temperatures up to 122°F.

The 800 kW Rental Power unit also has a smaller

footprint at a mere 30 feet long. The smaller container

offers greater flexibility in moving and locating units at

work sites or office buildings where space is limited.

The container is also insulated with sound attenuation to

keep down noise levels.

Tripp Lite Introduces RackmountUPS Systems for Network/TelecomWiring Closets

Tripp Lite has introduced three new SmartPro shal-

low-depth rackmount UPS systems designed to meet the

needs of network/telecom wiring closets. The UPS sys-

tems are designed for wiring closets that require a shal-

lower mounting depth, higher load capacity and longer

runtime than standard-sized rackmount UPS systems.

The new UPS systems feature a higher output capaci-

ty compared to standard-sized rackmount UPS systems.

Due to an optimal power factor, shallow-depth rack-

mount UPS systems allow users to safely connect a high-

er wattage equipment load to a single UPS system. This

is especially important in cramped wiring closets where

installing additional UPS systems and the electrical serv-

ice required to handle a higher load is often not an option.

These UPS systems increase capacity without sacri-

ficing efficiency. Higher efficiency, up to 97.5 percent,

reduces electricity costs by lowering energy consump-

tion. Select SmartPro shallow-depth rackmount UPS

systems also feature up to double the runtime of similar

standard-sized rackmount UPS systems. Longer runtime

supports the mission-critical equipment found in net-

work and VoIP/telecom wiring closets.

SMART3000CRMXL features a 3,000 VA/2,880 Watt

capacity (which can increase to 3,600 VA/3,600 Watts

with optional hardwire connection), a 4U height and a

17.75 inch depth. SMART2200CRMXL features a 2,200

VA/1,900 Watt capacity, a 4U height and a 17.75 inch

depth. SMART1500CRMXL features a 1,500 VA/1,440

Watt capacity, a 2U height and a 19.5 inch depth.

By Kevin Conlin, Vice PresidentSolarcraft, Inc.

In the April/May 2008 issue, Remote Site and

Equipment Management Magazine brought you part one

of this article from Solarcraft, Inc. Part one covered the

simple, but often overlooked gathering of accurate load

information and how to properly size a solar system

while selecting the correct size solar array, battery bank

and reliable components. This second half will cover

how to minimize field and installation errors, efficiently

use materials, basics of DC-UPS systems, hazadous loca-

tions, vendor selection and the ten commandments of

solar design. We hope you enjoy this continuation of a

great article. - ED

Preassembly and Testing Preassembly and testing assures minimal installation

time and trouble, even if the system has to be partially

broken down for shipping. Preassembly allows perform-

ance verification, and also allows you to provide a value

added service. By fully assembling the system, you are

assuring the end user that everything fits and works as

planned, and there should be nothing missing at the

installation. We preassemble and test everything, and

experience very few warranty claims even with a five year

warranty. It just makes sense if you are building for qual-

ity and reliability.

System IntegrationBy combining the power equipment with the electron-

ics, you improve system efficiency and material utiliza-

tion, reduce installation time, costs and materials, and

allow complete system testing and FAT (Factory

Acceptance Testing). Batteries should not be placed in

an airtight enclosure (Nema 4, 4X, 12 and 13) with the

electronics, as they may vent explosive gases. Proper bat-

tery ventilation is required by the National Electric Code

(NEC) and all battery manufacturers recommendations.

Even sealed batteries can vent explosive gases, as they

are not really sealed, but have small vents that will

“burp” if the internal pressure builds up to over 2 PSI.

The internal pressure is necessary for the recombination

of hydrogen and oxygen inside the battery, these gases

are given off during charging,

and when contained inside the

battery, allow it to be relative-

ly maintenance free, requiring

no added water during its life.

Wet batteries are much

worse, you can count on them

gassing both explosive and

corrosive gases, and their use

requires a much different sys-

tem design. They do have their

advantages in hot climates,

they will greatly outlast VRLA

batteries, offering up to 15

years of life, but they do

require semi-annual mainte-

nance of adding water and

probably removing corrosion

from the terminals.

When done properly, a well

integrated system will use one

large enclosure instead of three

to four smaller ones, with the

accompanying rack and conduit interconnecting the vari-

ous enclosures. Cost savings can reach 50 percent, and

the design is much cleaner.

Installation ConsiderationsWhere is it going? How will it be mounted and to

what? Pole-what size? Tower-what model? Wall or rack?

Handrail? Concrete pad? Wooden Pole? What is the skill

level of the installation crew? Do they have a compass?

Sometimes manpower is limited, and the batteries are

very heavy. These questions should be answered before

shipping the system in order to avoid installation problems

that can cost your customer a lot of money if they are not

prepared, or the system is not. If manpower is limited,

then mounting brackets and installation aids can be sup-

plied to allow one person to install the system safely.

Check for shading by an antenna, fence, heli-deck or

other nearby structures. If there is vegetation nearby,

especially tall trees, the solar day may be shorter than

you think. Remember that safety factor or head room?

It’s not a perfect world out there. Keep in mind that most

electricians are used to high voltage AC, and a complete-

ly different set of rules apply to low voltage DC installa-

tions. Electricians are not prone to asking questions, and

many a Master electrician has screwed up a solar instal-

lation. Make sure the installation manual is well written

with lots of pictures.

Our company has special heavy duty pallets built

because we have learned that when shipping heavy, valu-

able cargo, a regular pallet does not offer adequate

strength or protection in transit. We think a $50 pallet is

good insurance, and we experience very little

freight damage as a result. This is a lesson we

learned the hard way.

Never underestimate the power of an incompe-

tent freight handler, forklift driver or lazy trucker.

They can destroy in minutes a system designed to

last 30 years. You can also count on them denying it

and refusing your freight claim. I had one trucking

company insist I had shipped the system damaged.

DC-UPS GuidelinesBegin with the same step as solar, gather accu-

rate load information. Determine average load

current and the customer’s desired run time with-

out power. Allow

enough extra

capacity on the

DC-UPS power

supply to both

run the load and

recharge low bat-

teries simultane-

ously. Always

consider battery

capacity as a

function of the

rate of discharge,

the lower the dis-

charge rates rela-

tive to the battery capacity, the greater the capaci-

ty. Battery capacity at the eight hour rate is always much

less than the 100 hour rate. Allow for battery aging, espe-

cially in hot climates, and try to design the system so it

still meets spec when the batteries are due for replace-

ment and have lost some of their capacity.

Use sun shades in hot climates and insulation in cold

ones. Other packaging considerations are the same for

solar, know what type of power input you have. For

example, may municipal Wi-Fi applications are pow-

ered from street lights that only have power at night. In

these cases, consider the summer solstice, when the

night is shortest, day longest, and the system has to

replace the maximum amount of power during the

shortest night of the year. For cyclic applications such

as this, size the battery for a 20 percent daily depth of

discharge (DOD), this will give you between 1,000 and

1,500 cycles in a mild climate.

In a hot climate, the battery life is shortened. As we

discussed earlier, Gel and AGM batteries lose life in hot

climates, so for DC-UPS applications where there is line

power consider a small air conditioner or air to air heat

exchanger to keep the batteries cooler in summer. Both

allow cooling without introducing outside air, especially

important in dusty desert environments, or humid, salt

laden coastal or offshore sites.

Hazardous LocationsClass 1 Division 2, Groups C and D are the most com-

mon, usually on natural gas pipelines, refineries, chemi-

cal plants, grain or fuel terminals, well heads and off-

shore platforms. There are some standard, pre-approved

systems, but for large projects or OEM equipment, it is

recommended that the complete system, including the

load electronics, be approved by one of the major testing

laboratories, such as UL, FM or ETL. Class 1 Div 1 is

very difficult, and usually limited to very small systems,

with small solar/battery combinations, and utilizing

explosion proof enclosures and components.

Non certified systems near hazardous areas are usual-

ly located at least 15 feet from the pipeline or other

explosive gases source. The NEC must be followed, usu-

ally using intrinsic safety barriers, OEM approved inter-

face electronics, and by using rigid metallic conduit or

armored cable that is completely sealed internally to pre-

vent the migration of explosive gases into the non-haz-

ardous power system. Simply using Class 1 Div 2 com-

ponents does not

mean the system

is legal, howev-

er, the NEC is

somewhat vague

in this area, and

an experienced

electrical engi-

neer does have

the power to

approve such a

system if he

believes it fully

complies with

the NEC. An

example would

be an offshore

production plat-

form that is les

than 30 feet

across. In this case, it is physically impossible to

locate the equipment, such as navigation aids, the

required 15 feet away.

WarrantyI recommend a one year minimum, and a

five year is desired. Batteries are always pro-

rated, just as when you buy or replace a car bat-

tery. Beware of long, lengthy warranties written by

lawyers, they are likely not very good, for you any-

way. A simple, no hassle warranty is best, and the ven-

dor should offer to replace whatever is needed with-

out delay, sorting out the

claim is secondary to get-

ting your equipment back

up and running as quickly

as possible.

If you have done your

homework and designed

the system properly, and it

is pre-tested before ship-

ping, then the warranty

shouldn’t be an issue.

Keep in mind that cus-

tomers who might have

hundreds of systems

deployed cannot afford

warranty issues of any

kind. Acts of God, nature

and man are usually not

covered by a warranty, so

you should not expect a

system that has been struck

by lightning to be covered

under warranty. Solar

modules generally carry a

20 to 25 year performance

warranty, they are guaran-

teed to produce at least 80

percent of the original power spec after that time. My

experience shows that a good module will degrade very

little over time.

Vendor Reputation and Selection How do they present themselves and their products?

Lowest cost or highest quality? You can’t buy the best

equipment for the lowest cost, in spite of what you may

be told. Again, consider the consequences of failure, a

small cost savings can be quickly wiped out with a poor

quality system prone to problems or failure.

Check their website-how do their products look? Is

the information complete, or vague?

I’ve seen some websites that show the exact same pic-

ture for 20 different products. What is the warranty, and

the warranty caveats or conditions? Dig deeper- how do

they honor their warranties? Check references, especially

within your industry. Are they local or out of state? Do

they have a local rep? If they are out of state, and have a

electronic switchboard instead of a real person answering

the phone, then you may be on your own.

Ten Commandments of Solar DesignThis is a slightly humorous set of guidelines I wrote

for my customers, who are usually smarter and better

educated than I am. I can’t lecture them, but if I can

make them smile, then they might just listen.

I: Thou shalt clearly and accurately define thy load,

and add no additional loads in the future.

II: Thou shalt know thy site, especially in winter, and

avoid obstructions to the heavenly rays of sustenance.

III: Thou shalt be prepared for the attack of the he

then, the thieves, the vandals and those coveting

thy goods.

IV: Thou shalt not be guilty of using too few batteries,

for batteries are cheap insurance, and the heart of

thy system.

V: Thou shalt honor thy controls, for they are the soul

of the system, and must be temperature compensated.

VI: Thou shalt always ground thy system, for when the

heavens open up, lightning shall quickly find thy

system and destroy it.

VII: Thou shalt check thy system regularly, for the

ravages of time can be insidious.

VIII: Thou shalt consider the worst case scenario, for

it is written that this shall occur.

IX: Thou shalt build to last, and by seeking value, thou

shalt be held in high esteem by thy peers.

X: Thou shalt know thy vendor, for one day thy

salvation may lie in his hands.

Canon U.S.A. Introduces the VB-C60 PTZ Network Camera

Canon U.S.A., Inc. has

released the new VB-C60

Pan/Tilt/Zoom (PTZ) net-

work camera. This camera is

designed as a versatile, com-

pact solution for high-quali-

ty, remote-video monitoring

over IP and can be used for

many diverse applications..

Featuring genuine Canon

optics, the VB-C60 has a long

built-in zoom (40x optical) and wide angle lens (56° hor-

izontal field of view), as well as an auto focus system and

image stabilization.

The VB-C60 PTZ network camera’s wide panning

range (± 170) which, combined with the 56° wide angle

lens, provides coverage for a full 360° horizontal field-

of-view. When viewing moving objects, images remain

clear thanks to a high-sensitivity progressive-scan CCD

and auto focus system. The camera also features

panorama image creation in which the entire viewing

range is stitched together into one image. This allows

the user to quickly move the camera to any specific por-

tion within the cameras viewing range. Additionally, the

user can utilize the Pre-set Tour function, allowing for

up to 20 camera positions to be pre-set and viewed at

specified intervals.

The VB-C60 PTZ network camera uses the propri-

etary Canon DIGIC NET processor, a hardware-based

engine that performs all image processing and encoding.

This results in the camera being able to handle simulta-

neous encoding of Motion-JPEG and MPEG-4 video in

high-quality VGA (640 by 480) at a full 30 frames per

second. The high image quality of Motion-JPEG is suit-

ed for live monitoring; the compression scheme of

MPEG-4 is well suited for recording due to its smaller

file size and lighter network load. The VB-C60 PTZ net-

work camera offers support for up to 30 simultaneous

clients (users accessing and viewing video images at the

same time).

The ability to distribute Motion-JPEG images in three

sizes simultaneously: 640 by 480, 320 by 240 and 160 by

120 is also found on this camera and allows for access by

a cell phone/PDA. The 320 by 240 size is useful when

monitoring multiple cameras on a single screen; the 640

by 480 resolution provides for optimum image quality.

The VB-C60 also has a recording stream function that

can minimize the possibility of lost frames due to brief

network interruptions.

Also available on the VB-C60 is motion detection,

which can be triggered based on user pre-set parameters,

and subject auto-tracking, which automatically pans and

tilts to follow a subject’s movement. In addition to tracking

the detected motion, the camera can instantly take a picture

and email it to a designated account or cell phone/PDA, and

upload multiple images to an http or ftp server.

Included with the camera is IPv6 and IPsec support (IP

security), a set of protocols for securing IP communica-

tions by encrypting data streams while also securing the

data flow to and from the camera, ensuring only author-

ized users have access.

For convenience and ease of installation, the VB-C60

PTZ network camera supports the IEEE 802.3af standard

for Power over Ethernet (PoE) technology, which allows

both power and data to be carried over a single LAN

cable when connected to a PoE hub/switch/midspan.

Since a power cable is not required, the camera can be

installed at sites without accessible AC outlets.

The VB-C60 PTZ network camera comes bundled

with one license of VK-Lite network video monitoring

and recording software, an application that enables the

user to monitor, record and playback images from up to

four cameras from a single screen. There is also a built-

in Web Viewer for live monitoring and basic camera con-

trol, such as controlling the camera’s PTZ movements.

New Security Module DesignedSpecifically for SCADA ProtocolAnd Modbus

Byres Security, Inc. and MTL Instruments have built a

security module designed specifically for managing lead-

ing SCADA protocol and Modbus TCP. Named the

Tofino Modbus TCP Enforcer Loadable Security Module

(LSM), the unit performs detailed analysis and filtering

of all Modbus TCP message, and is certified by Modbus-

IDA. It allows owners of control and SCADA systems to

regulate Modbus network traffic to a high level of detail,

thereby increasing network security, reliability and per-

formance of critical systems.

Deep packet or content inspection for web email or

traffic has been offered in IT firewalls for several years,

but nothing has been available for the process control or

SCADA world. Modbus traffic could either be allowed or

blocked by a standard firewall, but fine-grained control

was impossible. Since the smooth flow of Modbus TCP

traffic is critical to the average industrial facility, engi-

neers usually opted to let everything pass and take their

chances with security.

Additional features include enhanced security and pro-

tection for any Modbus TCP device, including filtering of

invalid traffic that could cause denial of service or system

failures. The module also enforces read-only access to safe-

ty instrumented systems for enhanced isolation and safety.

9460 and 9470 Remote Area Lighting Systems (RALS).

The 9460 and 9470 complete Pelican’s line of area light-

ing systems which provide con-

venient and ecologically respon-

sible alternatives to generator

powered lights.

The 9460 RALS features two

swiveling telescope masts, each

extends to nearly 6 feet, and two

360° articulated light arrays. The

system’s combined 48 LEDs and

dual power modes, with two

water-proof switches, combine to

radiate 4,000 lumens in high and

2,000 in low. Powered by a

rechargeable battery, the system

offers up to seven hours of peak

brightness or 14 hours in low

power mode. The self-contained 1510 Carry-On Case,

the 9460 is engineered to take as little space as possible

and provide easy ground transport with a pull handle and

stainless steel ball-bearing, polyurethane wheels.

For large area illumination, Pelican has created

the 9470 RALS which features four fully-articu-

lated, 24 LED heads (96 total) mounted on four 6-

foot, telescoping light towers. The heads which

sport dual brightness settings are powered by a

12-volt, sealed, rechargeable battery and combine

for 8,000 lumens on high power for seven hours

and 4,000 lumens for 14 hours at low power. Self

contained in the durable 1610 Transport Case, it

features a pull handle and transit-friendly stainless

steel ball bearing, polyurethane wheels.

CIP requires periodically updating device passwords, and

the populations of IEDs and other CCAs, such as

Magnum DX router/firewalls in substations may number

in the thousands, makes automated update tools a neces-

sary administrative aid.

An event scheduler facilitates collections, archival and

Inc. for tailgating and reverse entry detection,

alarm, recording and prevention using Newton’s 3

Dimensional machine vision. While the US patent

is the first to be issued, world wide patents have

been applied for and are expected to be issued in

the future.

Tailgating is the act of an unauthorized person

slipping through a door into a protected area after

an authorized person. Piggybacking occurs when

an authorized person holds a protected door open

for another person that he or she knows or perceives to

have authorized access. Both acts completely remove and

circumvent the access control system’s ability to reject a

revoked or counterfeit pass or badge and to prevent unau-

thorized access to protected areas. In either case the

access control system, whether equipped with advanced

biometrics or just a simple card system, has no knowl-

edge of entry by the unauthorized person unless the tail-

gating/piggybacking is detected.

T-DAR’s stereo 3 Dimensional machine vision tech-

nology constantly monitors and accurately counts the

number of persons attempting to enter or present in a

given area and reports violators, including video evi-

dence, to security. When combined with a restricted area,

the T-DAR system prevents tailgating/piggybacking and

any other unauthorized entry. Additionally, combined

with other devices such as automatic immigration gates,

security revolving doors, portals or other restrictive

devices, Newton’s T-DAR technology guarantees that

only one person at a time will enter a secured area.

Newton’s T-DAR technology has successfully been

deployed for more than seven years in numerous appli-

cations around the world to control and track access to

restricted areas, including government installations, data

centers, power plants, secure manufacturing sites,

unmanned gates, security doors and virtually every other

category of secure areas.

Fastrax Completes Its Software GPS Offering withIT900 RF Module

Fastrax Ltd. has introduced the new IT900 module to complement the Fastrax GPS

software that was launched in May 2008. With the module, Fastrax brings a complete

software GPS solution to the market for cost effective

consumer device development.

Fastrax IT900 converts the GPS RF signal into a

digital IF that is processed by Fastrax Software GPS.

The software GPS has so far been ported to x86 and

ARM CPU’s and Windows, Windows CE and Linux

operating systems. The software can be ported to addi-

tional CPU’s, specific application processors and oper-

ating systems enabling a variety of platform options for

the end device manufacturers.

The software-based approach is expected to increase the speed of adoption of GPS

functionalities beyond the highest end cell phones and laptop computers. Target plat-

forms include mid-tier phones, digital cameras, laptops, personal navigation devices

(PND’s) and other devices used while on the move. While traditional GPS solutions

require the integration of a hardware component, making the design more complex and

adding to the cost, a software-based solution allows faster time-to-market with less

costs and easily adjustable features.

“Our goal is to be at the forefront of developing the most cost efficient, high quality

GPS solutions. With the launch of the new Fastrax IT900, we are now first to bring a

complete software-based GPS solution that provides a variety of options for the device

manufactures with a minimum cost,” said Taneli Tuurnala, CEO and president, Fastrax.

“Since GPS-enabled features are increasingly integrated in consumer applications, it is

clear that reducing all the possible costs is the key for the market development. With our

GPS expertise we can show to the industry how this is best achieved”, he continues.

Fastrax IT900 does not require any additional CPU or SRAM-memory for correla-

tion, acquisition and tracking. The Fastrax software GPS solution only requires an

absolute minimum of silicon. Once the IF signal is received from the Fastrax IT900, all

remaining calculations are performed in the software. This includes signal correlation,

acquisition and tracking as well as pseudo range calculations, navigation and final PVT

output. Additionally, the navigation sensitivity of combined IT900 and Fastrax software

GPS is as low as -163 dBm, while the un-aided acquisition sensitivity is -145 dBm.

Strong Growth in Asia Pacific PLC Market Continues The Asia Pacific market for PLCs continues to grow faster than those of other

regions. According to IMS Research, in its recently published report “The Worldwide

Market for PLCs- 2008 Edition” the Asia Pacific market for PLCs and directly associ-

ated software and services was estimated at $1,447.7 million in 2007, 17.5 percent

more than in 2006.

The knock-on effects of the 2008 US economic downturn and some lessening of eco-

nomic growth in Asia will tend to reduce PLC market growth. However, growing

domestic consumer demand in Asia, and an increased emphasis on quality control in

industrial production, will drive the Asia-Pacific market forward. For example, Chinese

domestic companies increasingly need to produce high quality products and this is driv-

ing more industrial automation. Increasingly, the Asia-Pacific market continues to

adopt the more advanced PLC technologies while the markets for the lower level, sim-

pler PLC products also continue to grow. More complex applications are emerging,

which require a higher level of functionality from the PLC.

Although the Asia Pacific market is dominated by the leading global PLC suppliers,

local suppliers are trying to increase their presence. China, India, Korea and Taiwan

each have domestic suppliers offering PLC products to the Asia Pacific region.

Constantly improving price-performance ratios of PLCs, increased competition, emerg-

ing technologies and growth of both new and existing applications - all contribute to

the current state, and future growth of the PLC market in the region.

Fieldbus Foundation and ISA Collaborate forWireless Initiative

The Fieldbus Foundation and ISA have reached an agreement to facilitate the

implementation of wireless backhaul transport networks. This technology initiative

is based on shared interests in serving the needs of end users and suppliers of wire-

less systems in industrial automation.

At an ISA100 meeting in June, ISA100 leaders established a new working group,

ISA100.15-Wireless Backhaul Networks Working Group to develop and maintain a

standard to address one or more dedicated or shared wireless backhaul(s) to support

technologies running multiple applications. The first of these backbones will be the

Fieldbus Foundation's High Speed Ethernet (HSE) implementation.

To expedite the work, the Fieldbus Foundation and ISA have entered into a

cross-licensing agreement allowing the two organizations to collaborate on wire-

less networks. To enable the ISA100.15 working group to develop the wireless

backhaul standard, it will be necessary to use extracts of Fieldbus Foundation spec-

ifications as well as parts of other ISA standards in development.

As part of the wireless backhaul network initiative, the Fieldbus Foundation and

ISA will develop a standard to interface between different technologies suitable for

backhaul networking, address wireless co-existence (frequency sharing) related to

the backhaul networks, define prioritization of multiple applications and ensure

quality of service, support multiple application protocol translators and address

security issues on backhaul networks. ISA will publish the technical documents as

a standard within the ISA100 family of standards, and the standard will be jointly

owned by the two organizations and used accordingly in the marketplace.
