For plants that want to start small but grow big, DFI302 is a linking device that provides all the

functionality required for a system. For medium to large size systems this is the most elegant

architecture available, a truly field based solution.

Fully Integrated

Unlike other Fieldbus interface solutions based on traditional controllers with interface modules

which need lots of accessories, the DFI302 is a complete integrated and self contained unit including

power supplies, impedance terminator or even safety barriers. DFI302 is therefore simpler to

deploy, maintain and expand. Because a single module implements four Fieldbus H1 ports (31.25

kbit/s), Ethernet and serial Modbus port directly on the controller without the need for separate

interface modules, the DFI302 takes a fraction of the space of solutions using individual modules and

is easier to work with. One of the major benefits of DFI302 is that you can build very lean control

systems without the complexity and cost associated with legacy DCS.

Overview

The DFI302 solution.

Smar is the only manufacturer to offer a complete Fieldbus system solution that not only

includes field instruments, interfaces and software, but also manufacture the accessories

required for field device power. A tightly integrated solution is thus achieved. Moreover,

your purchasing and vendor relations become simplified.

Modular

The DFI302 is a modular multifunction device with a DIN-rail mounted backplane into

which all components are installed, including modules for main power supply, Controller

(CPU module), bus power, and impedance. Modules are plugged-in using industrial grade

connectors and secured by a robust metal screw. Optionally a conventional I/O-

subsystem with modules for analogue and discrete inputs and outputs can be

connected. The modularity is key to the flexibility of the DFI302. Yet, since all modules

including the Fieldbus power supply subsystem plugs into the same backplane, the DFI302

becomes a single integrated unit.

Because of the modularity, the DFI302 is available in different controller module

performances and networking options, and with a normal power supply impedance or

safety barriers. A complete range of conventional I/O modules is available for the I/O-

subsystem.

Wiring for power and H1 Fieldbus is done using plug-in connectors making removal and

insertion easy and reliable. The connectors have an optional keying, preventing the wrong

wire from going into the wrong module. You will always connect correctly, eliminating the

risk of applying high voltage to a low voltage terminal. The DFI302 power supply module

is plugged directly into the backplane forming an integral unit, no separate bulk power

supplies are required. The power supply has built in diagnostics and dedicated LEDs

indicating normal operation and failure which make troubleshooting easier, especially in a

system with many units. An externally accessible fuse located on the incoming line side is

capable of being replaced without removal of the power supply module or disconnecting

any wiring. A very wide line-power voltage and frequency operating range makes a single

model suitable for use around the world, and ideal for use in applications even where the

line power is unstable. Wiring may be unplugged with power still applied, there is no need

to power down first.

System integrity on all levels

Unexpected control interruption can be both costly and dangerous. Therefore the DFI302

has been designed to ensure that SYSTEM302 has multiple layers of safety and enable you

to build a system fault tolerant from the ground up providing uninterrupted control. One

of the main advantages of having the control function distributed to the devices in the

field, is that because there is no controller unit the controller cannot fail, thereby making

the control loop more reliable. Another advantage over traditional DCS and PLC is that the

number of modules and other components are minimised, reducing the probability of

failure. Two identical DFI302s may be connected in parallel to provide redundant

functionality. A key to the fault tolerance is that the primary and backup are physically

separated to eliminate common causes. Because they have separate backplanes and may

be mounted in separate cabinets, they will not be subjected to the same stress, such as

radio interference or power surges. The DFI302 makes possible redundancy at every level:

Field Level:

Redundant transmitters;

Redundant sensors;

Segmentation of critical loops;

Fail-safe condition handling in field devices independent of controller.

H1 Fieldbus Level:

Redundant power to the Fieldbus instruments;

Backup LAS in field devices.

DFI302 Level:

Workstation Level:

You can relax secure in the knowledge that the DFI302 is very fault tolerant providing a good degree

of safety, and also a high availability ensuring minimum losses due to process downtime. Virtually

impervious, you can enjoy safe reliable control at all times. Because of the extensive self-diagnostics

in every part of the system, the operators are notified in case of any device or communication failure.

Industrial Strength

Mission critical control applications require a high level of safety and availability that cannot be

met by a PC or a PC in a black box. PC processors and desktop-derived operating systems are

designed for desktop application tasks far less critical with an emphasis on graphics and with

less stringent response requirement than control. These may need to be manually "rebooted"

after a power loss or "lockup". Such an architecture is not suitable for the control level of a plant.

The DFI302 is instead based on a powerful 32-bit super-scalar embedded RISC risk processor and

a stable embedded industrial grade real-time multitasking operating system designed for critical

applications and uninterrupted operation. True real-time performance ensures timely control.

This platform also requires less memory, therefore making it even more reliable. I.e. the DFI302 is

not a "software PLC". The DFI302 has no moving parts such as fans or hard disks.

DFI302 uses an embedded industrial

Ease-of-use

Because the DFI302 is a self contained unit, fewer modules are required and external accessories

are eliminated resulting in less wiring. Automatic detection and address assignment of controllers

as well as field devices makes deployment easier as no DIP switches has to be set, and there is no

risk for address duplication. The DFI302 basically needs no maintenance at all. The DFI302 firmware

is stored in a non-volatile Flash memory and can easily be upgraded using the FBTools wizard.

This wizard will guide you step by step through the download process making the procedure very

easy to follow.

The FBTools wizard makes

firmware upgrade easy.

Managing a system with many DFI302s is further simplified as the serial number as well as other

identification information and diagnostics can be accessed though the SYSCON engineering and

maintenance software. The FBTools wizard is also used for low level hardware diagnostics.

Scaleable

Expanding SYSTEM302 is very easy and comes at a minimal cost. Enlarging the system is as easy

as connecting additional DFI302s and connecting the field instruments to it. With each DFI302

you only need to connect four H1 Fieldbus wires, but can add as many as 64 field instruments in

one go. It could not be easier. Because it is so compact, most likely any additional cabinet space

may no be required.

The OLE communications server has a simple and flexible licensing scheme based on the number

of function block tags. Moreover, no hardkey is required. System sizes start from a few blocks so

that you can start small with just a pilot plant, or a single independent unit, and range up to

thousands so that you can grow large. Expansion is easy and low-cost. Existing parts are not

undermined. You don't outgrow such a system.

For the DFI302, FOUNDATIONTM Fieldbus, based on IEC 61158-2 and IEC/TS 61158-3 through 6, is the

primary means of interfacing with field instruments, and the DFI302 was especially designed for this

featuring integrated H1 Fieldbus ports directly connecting instruments. This architecture is much

leaner than older style DCS and PLC controllers which requires separate interface modules.

H1 Fieldbus Interface

Four H1 Fieldbus ports

Each controller module has one dedicated Smar FB3050 Fieldbus controller chip for each of the

four Fieldbus H1 ports providing reliable and high performance communications. The FB3050 is

an ASIC (Application Specific Integrated Circuit) designed by SRC (Smar Research Corporation)

especially for Fieldbus communications. The DFI302 makes its own data and data from the field

instruments available for display in workstations, and for alarm, trending and control in any part

of the control strategy, and allow operators to actuate on field devices. Four H1 Fieldbus ports in

a single module making it space saving and easy to use. One DFI302 handle as many as 64

devices that can be freely arranged over the four ports for maximum flexibility.

communications.

The four Fieldbus H1 ports are galvanically isolated from each other, the Ethernet network and all

other parts of the DFI302 preventing ground loops. The ports are also passive, i.e. they don't take

any power from the bus.

Communications Master

The DFI302 has communication master capability and may perform the LAS (Link Active

Scheduler) functions for the four buses connected to the ports. Essentially a LAS is the active

master of the Fieldbus responsible for the highly efficient communication and function block

ES

scheduling. The DFI302 also manages the H1 Fieldbus networks, responsible for monitoring and

diagnostics of the communication. Communication errors are indicated by LEDs on the front-panel

clearly indicate active communication or failure for each H1 Fieldbus port making it easy to

identify the port with problem even in a large system. Communication status at different levels of

detail may be viewed from the workstation. Errors are also logged and time stamped making it

easy to determine which field device and when that has problems.

Control In the Field

The DFI302 enables control in the field by being capable of handling Fieldbus networks with

sophisticated strategies of many function blocks and communicated links between transmitters

and final control elements, and giving the operator access to modes, setpoints and tuning

parameters etc. Through the DFI302 a wide range of function blocks can be instantiated in field

devices that has such capability. In combinations with Smar's powerful field devices, you can build

systems that meet and exceed the capability of legacy DCS and PLC. In the SYSTEM302 architecture

the control is typically distributed to the field instruments achieving single loop integrity for safe

and reliable control at all times. Field control provides true parallel processing and very high

capacity even with low controller loading. In SYSTEM302 and added field device means additional

resources, as opposed to legacy systems where it would mean less resources to spare.

Interface Redundancy

Two identical DFI302 may be connected in parallel and connected to the same Fieldbus ensuring

that there are two independent communication paths to the field instruments. The switching from

one path to the other is completely automatic bumpless.

The DFI302 also works hand in hand with other devices with link-master capability connected to

the same Fieldbus networks such as a second redundant DFI302 or the Smar field instruments to

provide several levels of LAS redundancy. If the DFI302 controller fails or the module is accidentally

removed, another link-master will automatically become LAS. Once the problem has been

corrected, the LAS function is automatically returned to the DFI302. Switching is completely

H1 Fieldbus Bridge

Data is transported from one H1 port to any another in the system to allow a variable in a device

on one Fieldbus network to be communicated to another device in the other end of the plant

connected to a H1 port on the same or a different DFI302*. DFI302 handles the communication

management to achieve this task without any special configuration being required from the

user.

Bridging between ports and between DFI302s.

The bridging capability allows integration of controls across all the areas of the plant. The

configuration software is structured according to the hierarchy stipulated by the ISA S88.01

standard, making it easy to manage loops distributed throughout the plant independent of their

physical location. Because a redundant pair of DFI302 can be connected in parallel, you can

ensure that the bridging function also is redundant.

bumpless. Communications management and LAS functionality switch-over for the four H1

Fieldbus networks is handled completely automatically by the DFI302. Only one of the DFI302

functions as the LAS at any one time, should it for any reason be unable to perform that

function, the second DFI302 automatically takes over. LEDs indicate which of the H1 Fieldbus

ports are active or has failed.

Plug-'n'-play Fieldbus

Using the DFI302 it is simple to install and commission Fieldbus networks and devices because it

automatically detects, identifies and assigns the address to a Fieldbus device once it is connected

to one of its ports. The system requires only a minimum of manual configuration. The live list

eliminates the need to ring out devices as done in the days of 4-20 mA, and is extremely helpful

when troubleshooting.

H1 Fieldbus Power Supply Subsystem

Fieldbus require special components, different from those used with analogue and smart instruments.

Unlike many other systems, the DFI302 solution is complete with a full range of tailored Fieldbus

power components. A high level of integration and compactness is achieved because the DFI302

was specifically designed for Fieldbus use, with a built-in Fieldbus power supply subsystem. When

the DFI302 is used in applications where field instruments need not be intrinsically safe, it has only

four modules plugged directly into a single section backplane. When intrinsic safety (IS) is required,

the DFI302 is mounted in the safe area and several isolated safety barrier modules are used.

Fieldbus power subsystem components include a full range of power supply, power supply

impedance, terminator, and isolating safety barrier.

The Fieldbus power supply subsystem components are housed in modules identical to the I/O and

other modules used in the DFI302. These modules provide a good protection of the terminals, easy

integration, neat wiring and it looks aesthetically pleasing. Power and Fieldbus wiring is done using

plug-in connectors which makes removal and insertion easy. The connectors have an optional keying

preventing the wrong wire from going into the wrong module. You will always connect correctly,

eliminating the risk of applying high voltage to a low voltage terminal. External field wiring have

multiple point plug-in type connectors so that modules are capable of being inserted into or

removed from their backplane without unscrewing external wires. It also allows all the wiring to be

made before module installation. Field I/O wiring is screwed on to the connectors. Every module is

isolated from the others. Each type of module is uniquely identified by a type number, serial number.

In addition, each module clearly indicates the designed input and output range and type. Quick-

reference charts are permanently attached to the inside of the modules' front door. The charts clarify

proper module wiring. On-line replacement of any module is possible without having to re-configure

system software, alter system wiring or cabling, or re-initialise. The modules either plug into the

DFI302 backplane where they are held in place by a robust metal screw, or may also be stand alone

in case which an individual bracket may be used for DIN-rail or direct panel mounting. The design

of the modules makes it possible to pack safety barriers close together reducing panel space.

The DFI302 Power Supply is a high performance standard 24 VDC output switch mode module. It

has a number of features that sets it apart from other power supplies, and make it ideal for use in

control applications. The module has built in diagnostics and dedicated LEDs indicating normal

operation and failure which make troubleshooting much easier, especially in a system with many

units. Spotting the faulty power supply module in a panel with hundreds of modules is easy. A

voltage free relay contact output indicates failure and may be used for remote alarming and

independent safety interlocks.

An externally accessible protection fuse on the incoming line side is capable of being replaced

without removal of the power supply module or disconnecting any wiring. The output is short circuit

protected, and is not damaged even by prolonged shorts. The DFI302 Power Supply is therefore

the ideal choice in critical operations. A very wide line-power operating voltage and frequency

range makes a single model suitable for use around the world, and ideal for use in applications

where the line power is unstable. Input may be either AC or DC. One (Power Supply module) can

power the (Power Supply Impedance - 4 ports module) or two (Power Supply Impedance - 2 ports

module) or two (Safety Barrier module).

smar

11F

Non-classified Area Fieldbus Power

The function of the power supply impedance is to provide an impedance between the power

supply and the Fieldbus network to ensure that the power supply does not short circuit the

communication signal on the Fieldbus. The power supply impedance is used when you have bus

powered devices, and intrinsic safety is not required. There are two different types, giving you the

option of two or four ports. The high packing density reduces the footprint of the system.

Because the Power Supply Impedance module is separate from the power supply unit, multiple

modules, and thereby several Fieldbus ports, can take power from the same power supply.

Because it is DC powered and contains power conditioning circuitry to eliminate noise and

fluctuations, it can take power from a central panel DC source, from a battery or solar panel in a

remote operation, or as a backup source. The Power Supply Impedance modules can also be used

with existing power supplies in a plant retrofit scenario.

An externally accessible fuse is located on the incoming line side, and the outputs are

individually short circuit protected, and are not damaged even by prolonged shorts. Short circuit

on one port does not affect another. The Power Supply Impedance module is therefore the ideal

choice in critical operations. It has built in diagnostics and dedicated LEDs indicating normal

operation and failure for each port which make troubleshooting much easier, especially in a

system with many Fieldbus networks. Spotting the faulty network in a panel with hundreds of

modules is easy. Short-circuits and faulty wiring is easy to detect. The Power Supply Impedance

module has a built-in terminator for each port which may be individually enabled or disabled as

required, further reducing component count, and thereby complexity and cost.

Fieldbus Power Redundancy

To ensure maximum system availability and safety, two identical power supply subsystems can

be connected in parallel. In case one power source fails, there is an automatic and bumpless

transition to the second source ensuring that communication and control are not affected.

DFI302 provides two or more

independent power sources for

redundancy.

Typically a redundant architecture instead consists of two complete DFI302s connected to the

same H1 Fieldbus networks.

The location of the terminator in a Fieldbus network depends on the topology. In a bus

topology it is mounted at the end of the main trunk. In a tree topology it is mounted at the

junction where the spurs branch out. A Fieldbus network requires two terminators, one in each

end. But because both the Power Supply and Safety Barrier modules have built-in terminators, a

Fieldbus network typically only require one additional terminator. When a network has

redundant Power Supply Impedance module, their internal terminators are not used, instead a

separate terminator is used at the Power Supply Impedance end.

Due to its small size and particular shape the bus terminator - BT302 can easily be mounted

directly in any junction box only using two screws. No rail is required. The BT302 is totally passive,

and therefore has no power consumption at all. Since it consumes no power, it does not affect wire

lengths or device capacities. The BT302 has an industrial grade packing, the internals of the BT302

are hermetically sealed, exposing only the terminals, minimizing impact from humidity and other

environmental factors. Connection of the BT302 is very easy as it does not have any polarity.

Intrinsically safe Fieldbus

terminator.

Intrinsically Safe Fieldbus Power

The DFI302 is located in the non-classified area and field instruments are connected through

safety barriers. The function of a safety barrier in a Fieldbus system is very much the same as that

of a barrier in a conventional system. The barrier limits the current, voltage, and power coming out

on the network-segment wires in the hazardous area, so as to prevent explosion due to ignition

of the hazardous atmosphere. However, in a Fieldbus system the barrier must also provide the

function of a communications repeater, so that the devices on the hazardous side segment and

safe side segment of the barrier can communicate with each other.

The Safety Barrier module is galvanically isolated with a trapezoidal output characteristic. When

this module is used, no power supply impedance is required, because that function is already built

into it. This of course makes engineering, installation and troubleshooting easier and more

economical.

The number of devices that can be connected on the hazardous area side segment depends on

their combined power consumption, residual capacitance and inductance. The wire is also an

important factor. Typically 6-8 devices are connected on the hazardous area side segment of each

Safety Barrier module. On the safe area side the communication and power is separate. Several

Safety Barrier modules can be connected to a single segment on the safe side, typically two Safety

Barrier modules per DFI302 H1 Fieldbus port is used. To simplify engineering and installation, the

Safety Barrier module has a built-in terminator on the hazardous area side.

A common misconception is that terminators when used in an intrinsically safe (I.S.) system in a

hazardous area don't need IS certification. That is not true. because a terminator contains a

capacitor, certification is required. BT302 has such certification and is therefore one of few

terminators suitable for use in hazardous areas.

SYSTEM302 uses the open Ethernet (IEEE 802.3 series a.k.a. ISO/IEC 8802) with TCP/IP and UDP/IP

(RFC 791, 768 & 793 etc.) protocols as its backbone control network. This network may be either

simple or redundant and operate at 10 or 100 Mbit/s* on shielded twisted pair cabling, much

faster than traditional control system networks. Several DFI302 may be connected to the same

Ethernet Fieldbus making very large systems possible. The DFI302 may also coexist with other

Ethernet devices on the same network thanks to the multi-protocol nature of Ethernet. Wiring of

DFI302 nodes and workstation nodes are physically arranged in a star topology using hubs, but

are logically connected to the same bus. This topology ensures that a problem with one node or

segment does not affect the communication with other nodes. Switched networks ensure

deterministic communications without collisions enabling Ethernet to be used as a control level

network passing time critical control variables and alarms, as well as configurations and

diagnostics. Business related information such as production and inventory reports may also be

disseminated throughout the enterprise on the same network in real-time. This ability to "mine"

live data enables users to run the company more efficiently. The Ethernet is used as a path for

both control and manufacturing information on the same network, flattening the old traditional

system architecture of several layers into an optimal solution. Workstations fitted with Ethernet

cards and other Ethernet device are also connected to the same Ethernet network.

Communication is possible between controllers, between workstations, and between controllers

and workstations.

For 10 Mbit/s 10Base-T wiring the maximum length of a segment is 100 meters. Up to four

10Base-T hubs may be cascaded achieving a maximum total length of 500 meters between

nodes. It is possible to use 10Base-FL fibre-optics between hubs to achieve greater distances. For

100 Mbit/s* type 100Base-TX wiring the maximum segment length is also 100 meters and the

total network span 200 m. It is possible to use 100Base-FX fibre-optics between hubs to achieve

greater distances.

The market dominance of Ethernet, and the use of standard Ethernet chips, NIC (Network Interface

Cards), hubs, switches and cables in SYSTEM302 bring the cost of the system down drastically as

compared to the proprietary protocols of legacy systems, while at the same time offering superior

performance. In short, the most cost effective solution available. Because Ethernet is used by so

may other manufacturers, the Ethernet network may also be used to connect subsystems for

advanced control, critical control or even business functions like ERP (Enterprise Resource

Planning). From a business perspective it is also safer to deploy Ethernet since the rapid

development and high volume of the commercial information technology (IT) world will always

ensure that future demands on higher data throughput at an affordable price is provided. You

don't have to get trapped with older technology. This compares very favourably against

proprietary solutions, which takes aeons to implement new technologies. You can remain

confident in a rapidly changing world. Since the technology is governed by an unaffiliated

standards organisation you can be reassured that compatibility with older technology is

maintained. Because Ethernet is a widespread technology, there is a wealth of options for media

available including twisted pair, coaxial cable, fibre-optics and wireless running different speeds

and with different distance limitations. In other words, the most flexible solution available. Since

DFI302 uses TCP/IP which is the protocol used on the Internet, you also get easy connection to the

Internet.

Control network redundancy for safety and availability

For critical applications the Ethernet network may be redundant. For redundant Ethernet Fieldbus

the wiring is simply duplicated. All Ethernet devices including the workstations are connected to

both Ethernet buses. The Ethernet hubs or switches are also duplicated. The DFI302 and workstations

continuously monitor both the Ethernet Fieldbus networks. Should either one fail, it will inform the

user and use only the good network. The switch-over is totally bumpless and transparent to the rest of

the system. Therefore process upsets are avoided, and control continues as usual. LEDs indicate which

of the Ethernet networks are operational or have failed. Smar can provide commercial or industrial

grade hubs for twisted-pairs or fibre-optics. Industrial grade hubs are DIN rail mounted and have

redundant power supply.

Easy to install and commission

The DFI302 works together with the SYSCON configuration and maintenance software (see separate

data sheet) to provide plug-'n'-play system operation and management by detecting, identifying and

assigning addresses to devices as they are connected, removed or have problems. Once connected to

the Ethernet Fieldbus the DFI302 or a workstation is detected and assigned its IP address completely

automatically, eliminating troublesome DIP switches and risk for address duplication.

Shielded twisted-pair cable is used for wiring the DFI302s and hubs together. The DFI302s have

simple RJ-45 connectors. No special tools or skills are therefore required. Installation is simple and

very fast. LEDs indicate active communication or failure. You connect and disconnect without

having to power down. The hub/switched based star topology means that you can disconnect

devices without disrupting control or communication of other nodes.

Converters for optical fibre are also available for long distance transmission, and to avoid

Ethernet Linking Device

The DFI302 controller module is a H1 Fieldbus linking device to the Ethernet network. Data in the

field instruments are accessible to workstations and other systems over the Ethernet. Fieldbus

instruments connected to one DFI302 can communicate seamlessly with Fieldbus instruments

connected to another DFI302 somewhere in the system without any special configuration by the

user. The DFI302 contains the buffers and logic to handle the speed and timing differences

between H1 Fieldbus and Ethernet, ensuring the the messages are sent in the correct format at

Installation.

Several features of the DFI302 were designed in to allow existing plants to slowly migrate to

Fieldbus while at the same time protect as much as possible of their investment in the existing

equipment. One such feature is a EIA-232 serial communication port on the controller module that

allows it to be connected to, and digitally communicate with, a wide range of legacy equipment

common in existing plants using the ubiquitous Modbus protocol. Until recently the Modbus

protocol has been one of the most popular de facto standards in the industry. Existing plants

often have many devices and subsystems using this protocol. The life of existing plant equipment

can be extended as its use can continue for another few more years, reducing the amount of

reinvestment at a plant revamp. The DFI302 can act as a master or as a slave, allowing it many

different roles as a Modbus gateway. Because the serial port is integrated into the DFI302

controller module, there is no need for a separate module resulting in lower cost, less complexity

making it easier to use, and less panel space is required.

Modbus RTU protocol is supported, and the port can be configured for different speeds etc. In

master mode the DFI302 can read and write data in Modbus slaves or data in the DFI302 can be

read or written by a master when the DFI302 operates in a slave mode.

polls data through the serial port and makes it available on the Ethernet, while at the same time

performing the normal Fieldbus tasks on the four H1 ports.

master role.

The DFI302 uses the standard Modbus commands for read and write making the slave data available

for use in the control strategy, or for display and trending in the operator workstation. Operator may

also actuate on the slave devices and perform other supervisory functions. Inputs are made available

as normal parameters, that may be used as part of the control strategy, or simply for monitoring, alarm

and trend.

Integrating Fieldbus to Legacy Systems

Because of the popularity of the Modbus protocol in the early days, most legacy systems such as

DCS or PLC have serial interface modules that support Modbus. This may be used to supervise

Fieldbus instruments through a DFI302 acting as a gateway. The DFI302 controller responds to

polls from the master on its serial port with data accessed from the relevant H1 Fieldbus port,

while at the same time performing the normal Fieldbus tasks on the Ethernet too.

Through the DFI302 Fieldbus devices can be connected to an existing legacy control system

enabling the existing system to access some of the capabilities provided by Fieldbus devices.

Traditional process variables and controller gains can be mapped from Fieldbus to the database of

existing system, but of course the existing system doesn't have the control level networking

bandwidth and software capability do fully benefit from the Fieldbus technology. However, it may

be acceptable in a transition period to an open system.

User friendly

The Modbus port is very easy to use. It can be configured without having set any DIP switches. A

status LED on the front panel indicates active communication.

The DFI302 was specifically, and primarily, designed to operate with Fieldbus instruments. All

common field instrument types are available in Fieldbus versions, therefore the amount of

conventional I/O points required in a system is drastically reduced and will eventually be

eliminated. However, since many applications require connection of old or new devices that don't

have Fieldbus communication, the DFI302 may also be fitted with conventional discrete and

analogue I/O on an extended backplane.

The DFI302 may be installed close to the sensors and actuators, thereby eliminating long wire runs

and associated marshalling panels and cable trays for the conventional I/O, with subsequent

savings further reducing overall system cost.

Conventional I/O-subsystem

backplane fitted with

conventional I/O modules.

Flexible and scaleable

Since the I/O-subsystem is modular, you need not worry about future expansion and spare

capacity now. Just buy what you require for your current application. The modularity gives you

the flexibility to mix and match the right quantity for each I/O type that you need. As your

demand increases or changes, additional backplane segments added and modules can be

plugged in to the system. Each controller module can be fitted with an I/O-subsystem for up to

256 points. Since several DFI302 can be networked together in a system, a very large amount of

conventional I/O can be handled.

smar

19F

The I/O-subsystem modules are multiple-channel high-density, typically packaged with as many

as 16 channels per module. The DFI302 therefore only requires half the panel space compared to

a device with only eight channels per module. And it is much lower cost too. Modules plug-in

using and industrial grade connector, and are held in place by a robust metal screw. All I/O

modules are isolated from the rest of the DFI302. All I/O circuits are designed so that accidental

normal-mode connection of 1000 VAC/DC to discrete I/O field terminals for an unlimited time

does not destroy any devices in I/O group other than the circuit to which the voltage was

applied.

The DFI302 Power Supply modules have a 24 VDC output used to power the I/O modules. It can

at the same time be used to power conventional field devices. There is no need for external bulk

power supplies. All is part of the modular DFI302. All modules are packaged in the same form

factor, allowing you to mix all types of I/O in any backplane position, irrespective of their voltage

levels. I/O modules are available of the following basic types:

Basic I/O Types

Discrete input - DC

Discrete input - AC

Discrete output - Transistor

Discrete output - Relay

Discrete output - Triac

Analog input

Analog output

Temperature input

Pulse input

The best way to measure temperature is to use field mounted Fieldbus temperature transmitters

(TT302). However, for applications sensitive to initial cost or in plant retrofit using existing wiring,

temperature modules in the DFI302 may instead be used. The temperature input module has a

universal direct sensor input accepting eight channels. The module has a built-in cold junction

compensation, temperature linearization and accepts the following sensors:

RTD: Cu10 (GE), Ni120 (Edison curve #7), Pt50, Pt100, Pt500 (IEC), Pt50 and Pt100 (JIS);

Thermocouple: B, E, J, K, N, R, S, T, L and U (DIN);

Voltage: -50 to 500 mV;

Resistance: 0-2000 ohm.

Because a single module accepts both thermocouples and RTDs, you have greater flexibility and

the amount of module types and spares required is reduced. Because it accepts low level signals

such as mV and ohm, you can use it with load cells and other sensors without the need for

intermediate signal conditioners.

ES

Ideally Fieldbus instruments shall be used as far as possible, but when not available the second

best way is to use field mounted Fieldbus to current converters (FI302) and current to Fieldbus

converters (IF302). These reduce the field wiring and make future migration of devices to Fieldbus

easier. However, for applications sensitive to initial cost or in plant retrofit using existing wiring,

analogue modules in the DFI302 may instead be used. The analogue I/O modules accept the

following inputs and outputs:

Analog input: 4-20 mA/0-20 mA/1-5 V/0-10 V/-10-10 V;

Analog output: 4-20 mA/0-20 mA.

A single analogue output module gives you the option of both current and voltage output to

meet varying requirements. Output modules are current limited and protected against inductive

loads. In case of failure, a discrete output is driven to an individually configured fail-safe position

being true, false or hold last position.

The pulse input module is capable of measuring frequencies up to 10 kHz.

See the ordering section for a complete listing of modules.

Connect non-Fieldbus Devices in new Systems

Modern plants require some sensors and simple devices that are still not available with Fieldbus

communication. These include discrete switches, contacts and solenoid valves, pulse signals from

flow meters, and direct input from temperature sensors. Moreover, although all of the most

common transmitters used in the industry are available from Smar or other manufacturers in

Fieldbus version, some rare types only exist in analogue versions. Using the conventional I/O-

subsystem, all analogue and discrete devices may be tightly integrated to SYSTEM302.

Upgrading Existing Installations

When the DFI302 is used in the revamp of existing plants the I/O-subsystem may be used to

interface the large amounts of conventional I/O from the existing instruments that will not yet

be upgraded to Fieldbus. Typically existing devices are eventually exchanged by Fieldbus

instruments, being replaced in stages. During the transition period until those instruments have

been replaced with Fieldbus devices the I/O-subsystem provides a smooth transition.

Easy to install

External field wiring have multiple point plug-in type connectors so that I/O modules are capable

of being inserted into or removed from their backplane without unscrewing external wires. It

also allows all the wiring to be made before I/O-module installation. Field I/O wiring is screwed

on to the connectors. The connectors have an optional keying which may be set in advance

preventing the wrong wire from going into the wrong module. You will always connect correctly,

eliminating the risk of applying high voltage to a low voltage terminal. Module damage

protection is not enough. If sensors or actuator wiring is mixed up, the plant can go haywire.

Keying can on DFI302 therefore be made unique for each and every connector (not just module

type) ensuring a correct match and safe operation. Thereby you ensure that only the intended

sensor goes to its assigned module channel. Each type of module is uniquely identified by a type

smar

21F

Unique keying for each connector

prevents mistakes.

All I/O modules have a LED to indicate that it is powered. Discrete modules also have clearly

visible local LED status indicators to monitor the status of each input and output.

The DFI302 can also perform control similar to a conventional controller module. With

SYSTEM302 you can therefore chose to do control anywhere, in a transmitter, valve positioner, in

the controller or in all of them at the same time. The graphical system configuration and

maintenance software (SYSCON, see separate data sheet) makes configuration entry,

management, documentation and troubleshooting very easy. DFI302 is suitable for continuous

regulatory and discrete control, as well as for batch applications. Tags are shared throughout the

system, hence there is no need to map or patch variables via additional blocks or elements. Data

from Fieldbus as well as conventional devices can be used in the control strategy. A built-in Y2K

compatible real time clock lets you build control strategies that take date and time of day into

account.

number and serial number. In addition, each Module clearly indicates the designated field signal

range and type. Quick-reference charts are permanently attached to the inside of the modules'

front door. The charts clarify proper module wiring. On-line replacement of any module is

possible without having to re-configure system software, alter system wiring or cabling, or re-

initialise.

The DFI302 itself requires no software license. Therefore you don't need to go through the trouble

of upgrading and registration when you expand your system.

Homogeneous Fieldbus Environment

The DFI302 use the same function blocks as Fieldbus instruments, same PID block, same AI block

etc. This means that one single software can be used to configure every part of the system,

transmitters, positioners and controller all in the same language. The problem of linking Fieldbus

blocks to proprietary languages is eliminated. SYSTEM302 lets you fully enjoy the benefits of

Fieldbus. The SYSCON configuration software can put the PID either in a transmitter, positioner or

controller by simply dragging and dropping. An analogue input looks the same if it is in a

pressure transmitter or a 4-20 mA input module in the I/O-subsystem. This makes the system

integrated and easier to use because you only need to install one set of hardware and learn one

single software.

SYSTEM302 gives you

the flexibility to do

control anywhere.

Fieldbus applied to a legacy system becomes heterogeneous as opposed

to SYSTEM302 with DFI302 which is homogeneous.

SYSTEM302 therefore compares favourably against hybrids of legacy architecture and Fieldbus

where the controller is configured in one language at one station, and the field instruments in

another language at another station (heterogeneous environment).

FOUNDATION Fieldbus Function blocks

The FOUNDATION Fieldbus (FF) functions blocks are especially suitable for continuos regulatory

control. Anybody familiar with the Smar CD600 controller or a DCS should feel right at home. The

DFI302 appears in the configuration tool as a device just like a transmitter or positioner on each

of its four H1 ports. Configuration download can be made to one part of the DFI302 without

affecting the control on the others making online changes and expansions easy without

disturbing the process. Blocks appear the same independent of their physical location. The

DFI302 block set include several advanced function blocks that complement the function blocks

in the field devices should they be required, resulting in a very powerful combination. The

Fieldbus blocks implement sophisticated schemes for status propagation between blocks,

making safety actions, reset-windup protection, and cascade initialisation etc. completely

automatic. Since the functionality is built into the blocks, no additional strategy building is

required to achieve these functions.

Function blocks receive inputs from other blocks, process them according to an internal user

selected algorithm and constants, providing an output which in turn is passed to the next block.

Input class blocks (in transmitters) receive their inputs from a sensor, and output blocks pass their

output to an actuator. Fieldbus blocks are exceptionally powerful, and a single block performs

several functions, reducing the number of blocks and configuration effort required.

Fieldbus blocks are primarily executed in devices in the field which results in better loop

integrity, while at the same time off-loading the controllers, reducing the number of controller

modules required, and therefore overall system cost.

The selected controller operating mode (run or hold) is clearly indicated on the front of the

controller by individual LEDs. The controller module continuously monitors its own status and

indicates power and failure via colour coded LED status indicators on each controller faceplate. A

relay contact on the module also change status at failure. This may be used as an additional alert

to the user, and as part of safety interlocks. Status indication include FAIL (the controller has

failed), HOLD (application program execution has been paused), RUN (normal operation), FORCE

(any I/O which is forced on or off ) etc.

A modern control system needs more than just configuration and monitoring software. More

than inflexible "closed" applications and inaccessible data associated with DCS. SYSTEM302

process visualisation, engineering and maintenance software run on a commercial or industrial

grade PC platform with the Windows NT operating system, which is the powerful basis for the

information architecture for today's enterprise. Windows is the de facto standard for computer

workstations. As Information Technology (IT) is playing and increasingly important role in the

process industry, SYSTEM302 is the platform to build upon.

In SYSTEM302, one or more of the computers operate in a server role. Work is carried out from the

same station or one or more workstation clients typically located in the control room. Client-

server communication is done using a combination of OLE, OPC, COM and DCOM technology, all

from the same server. The server accesses the DFI302 on the Ethernet network and makes the

information available to other workstations. All the information in the DFI302 itself and the

Fieldbus devices connected to it is made available to OPC and OLE clients.

OLE/OPC Client/Server Architecture

DFI302 26F

FB D

EVIC

ES

The DFI302 OLE server is a 32-bit application which essentially consists of two parts, the OPC (OLE

for Process Control) server and the OFC server (OLE for Fieldbus Configuration). OPC is a widely

accepted industry standard client-server technology for interchanging parameter values between

applications. OFC is a Smar initiative to fill in the gaps left by OPC. For example, OFC is used for

instantiation and linking of blocks and other functions required by Fieldbus but not provided by

OPC. The DFI302 OLE server inter-connects one or more client applications, such as the

configuration and maintenance tool SYSCON and the process visualisation. Multiple clients can

simultaneously access the server located in the same workstation or remotely over the Ethernet.

This enables a single distributed Fieldbus database to be shared among workstations, eliminating

inconsistencies.

OPC is the industrial version of OLE, it is tailored for the needs of industrial software. One of the major

benefits of OPC is that it makes information from the field available to a vast array of software for

supervisory control, historical trending, advanced control and auto-tuning, and also inferential sensing,

modelling, advanced control, optimisation and historians without the need for any drivers. There are

even OPC bridges that pass data from one OPC server to another such as from one system to another.

All kinds of software from different suppliers can therefore be added to SYSTEM302. New types of

software from many suppliers become available every day. Because OPC servers have been

developed for new as well as old field equipment such as programmable controllers etc., OPC is a

convenient way to connect existing equipment in a plant retrofit scenario, or to integrate other

subsystems. OPC makes things work together.

Single integrated system database

An OPC server feature called address space browsing gives SYSTEM302 a single integrated database

even if software from several third party suppliers are used. Once a tag has been created in a device, it

becomes available for access by client applications. From the client application you can browse or

navigate by pointing and clicking through a Windows explorer like hierarchy until you reach the

parameter. You don't have to retype any tags, eliminating problems due to typographical errors. Since

OPC is completely tag based, you don't have to deal with mapping of device addresses, memory

registers and bits and bytes etc. as was common with PLC and HMI combinations. OPC instead gives an

unprecedented level of integration and ease of use, yet complete openness and security.

Integrating with other industrial applications

Because DFI302 and its OLE server is built around a whole suite of open technologies, it is very

easy to integrate to other applications that perform various tasks such as Human-Machine

Interface (HMI), advanced control or Enterprise Resource Planning (ERP). Any application which is an

OPC client can access the Fieldbus data from the OPC server. SYSTEM302 is the only system which is

open in both ends, up and down. Any Fieldbus device, any OPC client for operation.

Integration with Excel and other MS-Office applications

An optional OPC client allows you to access process and production information disseminated

throughout the enterprise, not only for use by operators and engineers, but also managers and

others in the business domain of the plant. MS-Office applications such as Excel, Word and other

"front office" applications receive live real-time data piped straight from the plant floor onto

your desktop. Use continuos and discrete process variables, integrated totals and diagnostics to

generate professionally looking and easy to use reports in table or chart format using Excel. The

familiarity of MS-Office makes it possible for anybody to get the information they need to make

better decisions. Just put the data into your spreadsheet by browsing the OPC servers in the

system. There is no need to type any cryptic commands or deal with obscure terminology. You no

longer have to gather data "snapshots" manually which is tedious, error prone and untimely.

Instead data is continuously and instantly updated without errors.

The built in statistical and computational functions of Excel, as well as sorting and filtering

features make analysis very simple. It has never been easier to handle large amount of process

data. It is even possible to perform calculations using the powerful computational and lookup

functions in Excel and write it back to controllers and field devices.

Use Excel to report with Bar,

line, pie, area or other charts

on 2D or 3D charts.

The OPC link for MS-Office provides a convenient way to import live data gathered by any OPC

server. A live link can simply be made into the spreadsheet. Combined with the OPC server's

accessibility through scripting languages such as Excel Visual Basic, it becomes a powerful tool

that allows to completely oversee the plant floor from within the office.

Network Security

OLE and OPC are open technologies used to disseminate information across the enterprise. There

is therefore a need to protect the data. The OLE server therefore equipped with COM and DCOM

security features. The Windows NT server domain-based scheme has a single security database

and is therefore easy to manage. Setup is done from the normal Windows NT User Manager.

Gateway to other systems

Other systems in the plant such as existing legacy controls, or critical controls systems for

emergency shut-down or paper machine quality controls with large amounts of data can be

tied into SYSTEM302 with relative ease. A dedicated server station acting as a gateway may

be fitted with the appropriate interface and run an OPC server for the system in parallel with

the DFI302s, without going through a DFI302.

Another open system implementing OPC server can be tied to SYSTEM302 using an OPC bridge

to mirror data in one system onto the other and vice versa. This way information can be

exchanged for supervisory and control.
