Basic principles of the Foundation Fieldbus technology

2 Basic principles of the Foundation Fieldbus technology

Foundation Fieldbus (FF) is an internationally standardized digital communication system. In many areas, it is replacing analog signal transmission using a 4-20-mA interface, which is costly in terms of time and resources. Digital communication offers the following benefits over analog data transmission:

– Significantly less wiring is required. Digital signals and supply voltage are transmitted via one cable.

– It is much easier to commission and to add or remove field devices. Standardization allows exchanging of field devices across manufacturers.

– Parameterization, diagnostics and maintenance of field devices can be performed centrally.

– Data transmission is bi-directional and delivers more information, e.g. status and error messages.

Foundation Fieldbus (FF) uses 2 bus systems. One or more slower buses (H1 bus) with Manchester Coding (MBP) are connected to a fast bus system (HSE bus) with Highspeed Ethernet. The field devices are connected in parallel to the H1 bus and are supplied with energy via the bus line by a feed unit. The transition between H1 and HSE is made by means of bridges or gateways. With FF, individual field devices can perform automation tasks so that they no longer act as mere actors or sensors. This enables decentralized process processing, relieving the bus of part of the load.



2.1 HSE bus

Highspeed Ethernet (HSE) is based on Ethernet technology and has a data transfer rate of 100 Mbit/s. Bus access is arbitrary. Devices can access the bus at any time. This may negatively impact on real time processing, thus limiting suitability for applications in automation technology. However, if only a limited number of devices is connected, the high data transfer rate allows real time processing. In order to avoid high bus loads resulting from a large number of devices, it is possible to set up multiple HSE buses that are connected with each other by means of switches. Switches read out the target addresses of the data packets and pass data on to the appropriate sub-network.

2.2 Linking devices

Linking devices connect the fast HSE bus and individual H1 buses. They convert the different data rates and telegrams. Linking devices can be bridges or gateways.

2.3 H1 bus basic principles

2.3.1 H1 bus overview

The field devices are connected to the H1 bus. They are capable of executing automation tasks autonomously and of exchanging data directly at defined points in time. Several mechanisms are in place to ensure that multiple devices cannot transmit simultaneously.

2.3.2 Cable type

Field devices and fieldbus network are connected by means of twisted pair cables. It is not permitted to have multiple electric circuits connected to one cable. The electrical characteristics of the fieldbus cables determine essential properties such as the number of participants or distances. Cable type B and cable type A can be used. If cable type B is used, it is possible to connect multiple fieldbuses of the same type of protection to one cable. The shielded cable type A must be used for Dräger gas detectors. If cable type B is used, it is possible to connect multiple fieldbuses of the same type of protection to one cable.

1) Depends on the type of protection and the cable specifications.

2) A maximum of 4 repeaters is permitted between participant and master.

2.3.3 Stubs

The line between a connection box and a field device is called a stub. The following must be observed:

– In explosion-hazard areas, stubs must not be more than 30 m in length.

– Short stubs (< 1 m) count as linking devices and are not considered in the calculation of the total bus cable length. However, this does not apply if the sum of all short stubs amounts to 2 % of the total length of a bus.

– In non explosion-hazard areas, the maximum stub length depends on the number of field devices.

2.3.4 Explosion-hazard area application

To ensure intrinsically safe use of the H1 bus, barriers must be installed between safe areas and explosion-hazard areas

If networks are designed to be intrinsically safe, the “Ex i” type of protection applies. This type of protection does not only require intrinsic safety of the connected equipment but also relates to the entire electric circuit. The intrinsic safety of a network depends on the connected electric circuits. The circuit with the lowest intrinsic safety determines the intrinsic safety of the entire network. If a connected circuit is designed to comply with Ex ib type of protection, this type of protection applies to the entire network.

Intrinsic safety is verified using the FISCO model.

2.3.5 FISCO model

The FISCO model (Fieldbus Intrinsically Safe Concept) was developed by the PTB (Physikalisch-Technische Bundesanstalt, the National Metrology Institute of Germany) in order to facilitate planning, extending and installing of networks in explosion-hazard areas. Network design in accordance with FISCO makes it possible, for example, to exchange field devices or to extend the system without the need for recalculation. Field devices can be exchanged by plug-and-play.

Certain constraints need to be observed in order to ensure these and other advantages. All bus participants must comply with the FISCO model. Only one device may feed energy into the network. Field devices may only take out energy. When a field device is transmitting, no additional energy is fed into the bus. Field devices that require additional auxiliary energy must be at least one type of protection higher than the fieldbus circuit. For installation in accordance with FISCO, corresponding control drawings are included in the instructions for use for the respective gas detector.

Properties according to the FISCO model

2.3.6 Power supply and communication

Field devices can have their own power supply or be supplied with energy via the bus by a feed unit. In a bus-powered network, the field devices connected to the H1 segment derive the required current from the bus cable. Field devices have a current consumption of 10 - 30 mA at 9 - 32 V. When a field device is transmitting, it changes its current consumption by ±10 mA at 31.25 kbit/s. At an impedance of 50 Ω, this leads to a voltage change of ±0.5 V in the network. The voltage change is modulated onto the direct current supply of the H1 bus.

2.4 Bus access

2.4.1 Link active scheduler (LAS)

Via commands they send to the field devices, link active schedulers (LAS), also referred to as link masters, control and schedule the bus communication. Addressing of field devices is also controlled by the LAS. Assigned and unassigned device addresses are cyclically queried by the LAS. As a result, new field devices can be connected at any time. Bus systems can contain multiple LASs, which means that a failure of an LAS can be compensated for quickly.

Max. current requirement ≤ 110 mA ≤ 110 mA



2.4.2 Scheduled traffic

Data transmissions that are time-critical are performed by means of scheduled traffic. This includes, for example, controlling of process variables. Scheduled data transmissions follow a strict time schedule that is processed cyclically. This ensures that all data are transmitted in time and that bus access conflicts are prevented. The LAS synchronizes the field devices by means of a TD command (timer distribution). Every field device has the time schedule in its system management. It defines the task to be processed and the times at which data must be received or transmitted. The LAS can also use a CD command (compel data) to request transmission of the data.

Publisher subscriber method

When a field device transmits data, it takes on the role of the publisher, transmitting the data that are present in the transmission buffer. The data transmitted into the bus can then be directly read out and evaluated by field devices that are configured as subscribers. The data are not sent to a master first which would then control the appropriate field devices. This reduces the number of data transmissions within the bus to a minimum.

Example:

A gas detector is continually measuring gas concentrations and communicates its measured values cyclically. A fan is configured as subscriber of the gas detector..

2.4.3 Unscheduled traffic

Data transmissions that are not time-critical are performed by means of unscheduled traffic. This includes, for example, the parameterization and the diagnostics of the field devices. Free gaps in the time schedule for the scheduled traffic are used for unscheduled traffic. During these time gaps, the LAS releases the bus for unscheduled traffic. The LAS uses a live list and the PT command (Pass Token) for releasing the bus. When a device receives the token, it can access the bus until the time elapses or until it returns the token.

Live list

One after the other, all devices that are entered in the Live List receive from the LAS the token for unscheduled traffic. The LAS sends the PN command (Probe Node) to update the devices and addresses contained in the Live List. Newly connected devices then respond by sending the PR command (Probe Response) and are added to the Live List. Based on the order in the list, the device then receive the token for unscheduled traffic.Devices are removed from the Live List if they do not respond to the PT command issued by the LAS or immediately return the token after 3 attempts. Changes to the Live List are communicated to all devices. This helps prevent loss of information in the event of failure of an LAS.

Time 0: The gas detector is measuring. The fan is off.

Time 10: The LAS passes the token to the gas detector.

Time 20: The gas detector transmits its measured value or alarm into the bus.

Time 30: The fan receives the data sent by the gas detector. If it is an alarm, the fan switches itself on.



2.4.4 Sequence control for scheduled and unscheduled traffic

The LAS ensures, by means of sequence control, that the scheduled traffic is not interfered with by unscheduled data transmissions (PT Token, TD or PN command etc.). Before an unscheduled data transmission is performed, the LAS checks the time schedule for scheduled traffic. If unscheduled data transmission is not possible, the LAS waits in Idle state for a gab in the time schedule. When a gap occurs, the LAS issues the CD command. If there is enough time for a further unscheduled action, the LAS issues further command, such as the PN, TD or PT command.

2.4.5 Fieldbus access sublayer (FAS)

The fieldbus access sublayer builds communication relationships (VCRs) between the bus participants. Foundation Fieldbus uses 3 VCRs. They describe communication processes that enable speedy processing of tasks.

Publisher/subscriber

Sending and receiving of process data in scheduled traffic.

Report distribution

Sending of alarms, events and trend data in unscheduled traffic.

Client/server

Diagnostics and modification of field device settings in unscheduled traffic.

2.4.6 Fieldbus message specification (FMS)

Data transmission between bus participants is carried out by means of a set of standard telegrams, which are defined by the FMS. The data contained in standard telegrams are allocated to object descriptions. Each object description has data from specific blocks and associated objects of the field devices. To make sure that the object description can be correctly interpreted by the receiver, the description of the object description itself is included in Index 0. This description is referred to as object dictionary. The entries of indices 1-255 contain standard data types. From index 256 upward, the telegrams contain application specific data.

32

2.4.7 Function block model

An open protocol specification is needed to ensure that devices from different manufacturers can communicate with each other. The protocol specification defines consistent device functions and application interfaces. The general structure of the data transmission is assigned to 3 different blocks. In addition to the blocks, 4 objects are defined. Blocks and objects are represented in the software of the respective field device and define the functionality of the field device. The further subdivision by objects reduces the time for access to the data.

2.4.8 Transmission of measured values and status

The data blocks for the transmission of measured values and status are 5 bytes in length. The first 4 bytes contain the measured value as a floating point number in accordance with the IEEE standard. The 5th byte is used for device specific status information. The device specific status information is given in accordance with the NAMUR standard NE 107. If an error is present, it can be read out using the DTM.

Block types

Resource block (RB)

Each field device has only one RB. It contains the character-istic data of the field device, such as manufacturer, serial number of each assembly, software version, command for re-setting to factory settings, the status of the field device.

Transducer block (TB)

The TB bundles parameters that describe the type of sensor or influence the sensor. In addition, parameters for calibrat-ing, for target gas adjustment, for alarm configuration (alarm thresholds), maintenance and self-testing function, etc., are integrated. Nearly the entire menu functionality is contained. The raw data of the sensor are converted in the TB into a measured value. The measured value is then processed in the function block.

Function block (FB) Each field device has at least one Function block. It defines the access to the functions of the field device. The FB also forms the basis of the time schedules for scheduled traffic.

Objects

Link Link objects define the connections between function blocks in a field device and in the field bus network.

Alert Alert objects document alarms and events in the field bus net-work.

Trend Trend objects support long-term storage of function block data.

View View objects support the representation of the function block data and parameters. To this end, the data and parameters are subdivided into different groups that correspond to the respective type of task, e.g. process control, configuration, maintenance, additional information.

Byte 1 Byte 2 Byte 3 Byte 4 Byte 5

Measured value as a floating-point number in acc. with IEEE 754 Status



2.5 Device management

2.5.1 Device description (DD)

The device description (DD) of a field device is required for diagnostics, maintenance and integration of the field device into the process control system. The DD is written in a standardized file format and is included in the scope of supply of a field device. It contains device specific parameters that are needed to integrate the field devices with the fieldbus, including: input data, output data, data format, amount of information and, if required, device icons that are represented in the network tree of the control system. For the scheduled exchange of measured values the DD suffices.

Standard DD and manufacturer specific DD

There are manufacturer specific DDs and standard DDs. The standard DD differs with regard to the number of the individual function blocks and makes it possible to exchange devices independently of the manufacturer. Thus it does not offer the full functional scope of a manufacturer specific DD.

Dräger recommends the use of the manufacturer specific DD.

2.5.2 Device management in scheduled traffic

The device management in scheduled traffic is controlled by the LAS. Here, the measured value and the status of a field device are queried. The DD is required to integrate a field device into the scheduled traffic.

2.5.3 Device management in unscheduled traffic

In unscheduled traffic, field devices are set up by means of a PC or a service tool. The PC is connected to the HSE segment via an interface. The interface descriptions FDT and DTM were specified in order to capture device properties and operating functions of the field devices across manufacturers:

FDT and DTM

The FDT/DTM concept serves the purposes of integration and management of intelligent field devices. The concept makes it possible to configure field devices centrally, to document their measured values and their behavior and to perform device diagnostics.

DTMs (Device Type Managers) are software components that can be used to implement all functions, properties and parameters of the gas detector. Manufacturer specific DTMs also contain the complete control panel and the menu structure of the field device.

The FDT (Field Device Tool) is a cross-manufacturer concept enabling parameterization of different field devices using just one software. This software is a framework application into which the required DTMs can be loaded. This concept can be compared with the way printer drivers are loaded into an operating system.



Communication DTM (COM_DTM)

The Communication DTM is a driver that sets up the interface between fieldbus cable and the PC. This interface can for example be a USB-Ethernet converter. The Communication DTM is installed within the FDT framework application.

2.6 Current and voltage on the H1 bus

2.6.1 Current calculation

The following values need to be known for the calculation:

– IS = Feed current of the power hub

– IB = Base current of each field device

– IFDE= Fault current of each field device

The maximum number of field devices on the H1 bus is a function of the feed current of the Power hub used and the current consumption of the field devices.

The current requirement of the segment ISEG is calculated as follows: ISEG = ∑IB + max. IFDE

A segment is permissible if IS ≥ ISEG.

32

16

3



2.6.2 Voltage at the last field device

The minimum operational voltage (9 V) must be verified at the field device that is the most distant from the feed unit, since the cable resistance causes a voltage drop.

The voltage is calculated using Ohm's law:

UB = US – (ISEG * RSEG)

Where: UB = Voltage at the last device

US = Feed voltage of the feed unit (manufacturer's data)

ISEG = Current requirement of the segment

RSEG = Cable resistance = bus length * specific resistance

2.6.3 Voltage calculation and line length

The following formula is used to calculate the maximum cable length for a specific cable resistance.

32

17

0



2.6.4 Example of worst case calculation

In certain cases, the maximum line length can be negatively affected by the distribution of the bus participants in the segment.

RL = Line resistance of line segment χ

In = Current consumption of the nth field device

Given values (from current calculation and data sheet of the cable type):

ISEG = max. direct current (incl. IFDE) = 100 mA

RL = Specific resistance of cable type A = 44 Ω/km.

To ensure proper functioning of a field device, the input voltage at the bus line must not be lower than 9 V.

Thus the following obtains for the maximum voltage drop over the line: ULmax = US - 9 V.

Example: Feed unit with Ex interface

Feed units with Ex interface supply a voltage of 12.8 V.... 13.4 V.

Thus we obtain the maximum voltage drop over the line ULmax = US - 9 V = 12.8 V - 9 V = 3.8 V

The max. line resistance RLmax[Ω] = (ULmax/ ISEG) = 3.8 V / 0.1 A = 38 Ω.

Thus we obtain the maximum line length [km] = (RLmax/ RL) = 38 Ω/ 44 [Ω/km] = 0.863 km

Installation in the H1 segment - field devices in general

3 Installation in the H1 segment - field devices in general

3.1 Grounding and shielding

Intrinsically safe fieldbus circuits are operated in floating mode, although individual measuring current circuits may be grounded. In some cases, overvoltage protection needs to be placed upstream. The decision as to whether overvoltage protection is to be used and the responsibility for proper integration into equipotential bonding lies with the customer.

Sufficient equipotential bonding must be in place for the grounding of the conductive shielding. The grounding of the shielding protects the digital signals on the fieldbus against high-frequency electromagnetic interference.

Dräger gas detection equipment is only approved for capacitive grounding. The legal EMC requirements are only met if the shielding is grounded at the control unit at one end.

There are 3 methods for the grounding of the shielding.

– Isolated installation

– Installation with multiple grounding

– Capacitive installation

3.1.1 Isolated installation (IEC 61158-2)

The grounding of the cable shielding is separate from the device grounding and is only applied at the feed unit. The disadvantage of this method is that the bus signals are not optimally protected against interference. The degree of interference depends on the length and topology of the bus.

3.1.2 Installation with multiple grounding (IEC 79-13)

All cable shields and devices are grounded locally. The grounding lugs are connected to an equipotential bonding conductor that is grounded in the safe area. This grounding method achieves increased protection of the signals against interference and may be used, subject to conditions, in explosion-hazard areas.

3.1.3 Capacitive installation

The cable shields are grounded via a capacitor. The capacitors have an electric strength of 1 nF/1500 V. The overall capacity connected to the shielding must not exceed 10 nF. A shielded and twisted cable must be used.

Capacitive grounding in non-explosion-hazard areas:

– Field devices and connection boxes are capacitively grounded between cable shielding and earth. The capacitors are installed inside the connection boxes.

– The feed unit is grounded using the normal method.



Capacitive grounding in explosion-hazard areas:

– The connection box is grounded using the conventional method.

– The feed unit is capacitively grounded. The bus shield must be grounded directly at the feed unit.

– At the Dräger gas detector, the shield is inserted into the PIN provided for that purpose.

3.2 Termination

Passive termination is required at the beginning and end of each segment. The termination suppresses signal reflections on the bus line. Termination is achieved by means of a combination of a resistor and a capacitor (RC element).

3.2.1 Termination of an MBP interface (on the H1 side)

– The linking device at the beginning of the segment has an in-built bus terminator.

– In the case of a branched bus segment, the field device that is the most distant from the linking device forms the end of the bus and needs to be terminated.

– If the connected stubs are longer than 30 m, termination must be installed directly at the field device.

– If the bus is extended using a repeater, the extension also needs to be terminated at both ends.

Termination in non-explosion-hazard areas

In most connection boxes, bus termination can be activated by means of a switch. Where this is not the case, a separate bus terminator needs to be installed.

32

17

1



Termination in explosion-hazard areas

Connection boxes with switchable termination resistors are not permitted. The termination resistor must have appropriate approval and is installed separately.

3.3 PD tag and addressing

PD tags (physical device tags) are alphanumeric IDs for field devices. PD tags can be up to 32 characters long. In addition, each bus participant needs to have a unique address. Setting of the address is performed centrally by means of FDT and DTM. Addresses occupy ranges between 0 and 255. LASs receive addresses in the range 1-15. Basic Devices are addressed in the range 16-247. Field devices are automatically detected by the LAS and then receive an address from the default address range, i.e., 248-255. Dräger gas detectors can only be used as basic devices and are supplied ex factory with the address setting of 247 and the PD tag (product name serial number, e.g. Polytron 8000______ ERHK-0214). If two Dräger gas detectors are present in the same segment, one device will keep its address, while the second device will be assigned an address from the default range.

During setting, the field devices can assume 3 states. If the field device state is not SM_OPERATIONAL, no function block can be executed. If the address of a field device is deleted, the field device receives a random address from the default address range, until it is set up again. To this end, the device ID must be known at any time.

5.1 Checking the installation

1 Check for correct connection of the cables (see 4.3 Connecting the fieldbus cable)

2 Check the voltage at the gas detector.The minimum operational voltage is 10-32 V.

5.2 Configuring the gas detector via DTM

Gas detectors can be configured by means of the DrägerServicetool or a PC on which the FDT framework application and DTM are installed.

5.2.1 Preparing for configuration using FDT/DTM

1 Procure the required software.Software is available free of charge or linked at www.draeger.com. Required are:

– FDT frame application (e.g. PactWare)

– Communication DTM (e.g. ProfiTrace)

– Polytron 8000 DTM

2 Save and unzip the software locally.

3 Install the software, following the respective installation wizard.

4 Via an H1 interface, connect the PC to the fieldbus cable.

5.2.2 Establishing the connection to the fieldbus

To establish the connection to the fieldbus, the H1 interface must be added to the FDT frame application and the Communication DTM must be set up.

Preconditions:

– FDT frame application installed

– Communication DTM installed

– USB-H1 converter connected

1 Start the FDT frame application

2 Add the H1 interface.If PactWare is used:

a Right-click on HOST PC (2) and choose Gerät hinzufügen.

b Highlight the driver for the connected Profibus interface.

c Choose OK.



5.2.3 Establishing the connection to the gas detector

To establish the connection to the gas detector, the gas detector must be added to the Communication DTM.

Preconditions:

– FDT frame application opened

– Communication DTM set up

– Gas detector connected to the fieldbus

– Polytron 8000 DTM installed

1 Start the FDT frame application.

2 Find the node of the field device.If PactWare is used:

Troubleshooting

6 Troubleshooting

6.1 Fault analysis

If communication with the gas detector cannot be established, check the following items:

– Verify that the address (node) of the field device is the same as the address specified in the DTM.

– Check if the USB-Ethernet converter is correctly connected to the PC and to the fieldbus cable.

– Check the termination at both ends and, if applicable, at the transitions of the fieldbus cable (linking device, connection box).

In order to be able to establish a connection, all parameters in the gas detector and in the Communication DTM must match.
