1. INTRODUCTION

Foundation Fieldbus is an industrial fieldbus which allows connecting actuators and other devices (sensors, etc.) to a Distributed Control System (DCS) or a Programmable Logic Controller (PLC). Many actuators and other devices can be connected on a fieldbus line provided they are all equipped with a compatible Foundation Fieldbus interface.

Foundation Fieldbus uses standard Function Blocks.

A Function Block could be:

digital output (DO) such as commands “open” and “close”,

digital input (DI) such as feedback status “valve open”, “valve closed”.

analog output (AO) and analog input (AI) for signals as position signals.

Proportionnal / Integral / Derivative (PID) control may be performed by the field through the use of Function Blocks.

The Foundation Fieldbus interface described in this document has been specially designed for the Bernard actuators with INTELLI+ control.

Control box with inside Foundation Fieldbus interface could be supplied to connect other equipment.

Please make sure to get and read the INTELLI+ instructions for start-up (ref. NR1151) prior going further with the setting of the INTELLIBUS FF interface.

3. FOUNDATION FIELDBUS INTERFACE

3.1. Hardware description

The Fieldbus module “INTELLIBUS FF” located in the actuator is plugged onto the main Intelli+ board. No access is required.

3.2. Cable requirements

The cable must be specified for Foundation Fieldbus type A.

An example of a cable below:

Cable Characteristics

Belden 3076F

1 pair 18 AWG

Resistance: 5.86 ohms/1000ft @20°C

Nominal mutual capacitance @ 1kHz:

80pF/m (24pF/ft)

Shielding : shielding braid or

foil

Fieldbus cable must be installed according to the following requirements:

A distance of 20 cm must be kept with other cables

It must follow a specific cable path and be connected to the earth

All actuators using Fieldbus must be at the same earth electrical potential

3.3. Fieldbus connection

Fieldbus is connected according to the following schema:

Common cable shielding is connected to a terminal of the actuator (34 here)

Cables are connected on 2 terminals of the actuator (35 & 36 here). Corresponding input and output cables are connected on the same terminal.

A termination has to be installed at each end of line. This termination is not built in the actuator.

3.4. Intellibus Set-up

The INTELLIBUS module is selected in the menu:

How to set-up Intellibus

1) With the local control knob of the actuator, select Change, then Fieldbus, then Card FF present.

2) Validate with Yes.

3) Confirm with the red knob.

4) To save, select return in each submenu until reading RETURN (Change OK?) Then confirm OK with the red button.

When the Fieldbus card is selected, the menu shows 2 other settings:

Lost communication This settings allows to configure actuator behaviour in case of communication loss

o Which position the actuator goes to closed position, open position or stays in position. Default setting is Stayput.

o Controls state: in case of loss of communication, all controls are reset. For example, if the auxiliary control AUX1 is set on Local control inhibit when communication is lost, local controls are available again.

Cmd by fieldbus The default setting is Yes. If No is selected, then no command is taken into account through the Fieldbus. Only indications are transmitted.

3.5. Display indication of fieldbus communication status

An indication of the fieldbus communication status is available on the actuator display.

No data exchange (empty square)

Data exchange (rotating triangle)

Intellibus module fault (blinking cross)

(x) can have the following values :

O: On/Off mode command from DO blocs

A: Auto-mode command from AO blocs

Blanc: No FF command only wired command

FF(x)

3.6. Emergency supply

The actuator Intelli+ is normally supplied by the mains but in case of loss of power supply an emergency supply could be used to continue to communicate through the Fieldbus. This emergency supply needs 24V DC 4W.

The optional extra battery is also an alternative to be able to read the display during power off period but also to update the position in case of a change. The right position is then updated through the Fieldbus communication.

4. Fundational FIELDBUS TECHNICAL OVERVIEW

4.1. Foundation Fieldbus communication

4.1.1. Link Active Scheduler (LAS)

The INTELLIBUS FF interface can communicate with Distributed Control System (DCS), Programming Logic Controller (PLC), Personnal Computer (PC) or other devices from various suppliers equipped with Foundation Fieldbus.

Communication on the Fieldbus is managed by a Link Active Scheduler (LAS).

Characteristics of the LAS

The LAS has a list of the devices connected and sends cyclic messages to all devices. It also sends a Pass Token message, allowing an actuator to transmit unscheduled messages.

Any Link Master device may becoming a LAS.

The Fieldbus may have multiple Link Masters. If the current LAS fails, one of the Link Masters will become the LAS and the operation fieldbus will continue.

The actuator with INTELLIBUS FF could be a LAS.

Actuator address

There is no address configuration to the actuator level. This is performed automatically by the Link Active Scheduler (LAS). New actuators may be added to the Fieldbus anytime. The LAS periodically sends Probe Node (PN) messages to the addresses not in the live list. If an actuator is present at the addresses and receives the PN, it immediately returns a Probe Response message. If the actuator answers with a PR, the LAS adds the actuator to the live list and confirms its addition by sending the actuator a Node Activation message.

4.1.2. Function Block

A function block is like a black box inside the INTELLIBUS FF interface with input and output parameters. Function Block is used by the control system to communicate through the Fieldbus.

Function block name:

Discrete input (DI) (input in a fieldbus view) - for example: valve is open

Discrete output (DO) - for example: close the valve

Analog input (AI) - for example: valve is 50% open

Analog output (AO) - for example: close the valve at 30%



8

In each function block there is a list of parameters available (see §5).

Another Function Block is the Proportional / Integral / Derivative (PID) to perform control loop (see §7).

4.1.3. Transducer Block

The Transducer Block contains information not used for the process such as manufacture date, dead band setting, and opening and closing torque/position curve. (see §6)

4.1.4. Ressource block

The Resource Block contains data specific to the hardware associated with the resource. This includes the device type and revision, manufacturer ID, serial number and resource state.

The resource block contain also the Field Diagnostic parameter (see §8)

4.1.5. Device description

To achieve interoperability Device Description (DD) technology is used. The DD is like a “driver” for a printer. Bernard Controls supply the Device Description for the INTELLIBUS FF interface.

4.2. Foundation Fieldbus technology

4.2.1. Fieldbus Signaling

The transmitting device delivers +/- 10mA at 31.25 kbit/s into a 50 ohm equivalent load to create a 1.0 V peak-to-peak voltage modulated on top of the direct current supply voltage. The DC voltage can range from 9 to 32V.

The maximum DC current available depends of the fieldbus power supply.

4.2.2. Maximum cable length

The Fieldbus cable coming from a PLC is connected to the first actuator then the Fieldbus cable links this actuator with the next one and so on. All actuators are connected to the line one after the other until the last one. No return to the PLC is required.

The 31.25 kbit/s fieldbus allows ramifications or “spurs” but with restrictions

Cable length = Trunk length + total spur lengths

Maximum length = 1900m (6200ft) with “Type A” cable

Devices Max total spur length

25-32 No spur No spur

19-24 30m 100ft

15-18 60m 200ft

13-14 90m 300ft

1-12 120m 400ft



9

Possible number of devices possible on the Fieldbus will vary depending on the power consumption of each device. The INTELLIBUS FF consumption is 20mA and the minimum voltage allowed is 9V. It is necessary to check the available voltage at each actuator.

Example

With a cable type Belden 3076F - 23 ohm/km at 70°C (46 ohm for 2 wires) INTELLIBUS consumption 20mA, minimum voltage 9V. Fieldbus supply voltage 24V The drop in voltage due to the consumption is calculated by Drop in voltage = Cable resistance × Current. Results are summarized in the following table.

Length Nb of actuators supplied

Current (mA) Drop in voltage Segment m ft

200 656 5 100 0.92

50 164 4 80 0.18

50 164 1 20 0.05

70 230 3 60 0.19

70 230 2 40 0.13

60 197 1 20 0.06

700 2297 1 20 0.64

Total 1200 3937

Total fieldbus length ( to sum) is less than 1900m.

Spurs length ( + ) is less than 120m

The last actuator has a supply voltage of:

24V − − − − − = 22V (> 9V) that is enough to work.

Main trunk Main trunk



10

4.2.3. Terminator

A terminator must be connected at each end of the main trunk cable. Note: There is no end of line terminator inside the actuator. This terminator is made with a capacity in a series with a resistor.

4.2.4. Number of devices possible on the Fieldbus

The number of devices depends of the power supply of the Fieldbus. With a supply of 24V 350mA it is possible to connect until 17 actuators (each actuator needs 20mA)

4.2.5. Repeaters

Adding repeaters modules allows to increase both the number of actuator on the line and total line length. Each repeater allows to lengthen the line by 1900m. See §4.2.2 to know the possible device number and maximum length for each segment.

According to the type of repeater, it is possible to use until 4 repeaters. Take also into account the repeater consumption on the fieldbus (usually 30mA). The important advantage of the repeater compared to other repeater-free technologies is to keep the communication speed unaffected and therefore to get a very short response time.

Bernard Controls can supply weatherproof or explosion proof repeaters.

5. CONTROLS AND INDICATIONs

With Foundation Fieldbus system, controls and indications are organized in Function Blocks. For actuator controls (§4.1) there is Function Block Discrete Output (DO) or Analog Output (AO). Output is a Fieldbus view: output of the Fieldbus. For actuator indications (§4.2) there is Function Block Discrete Input (DI) or Analog Input (AI). These data are mainly use for the processing. For configuration, setting and maintenance the data are brought together in the Transducer Block (§5)

5.1. Actuator controls

Actuator control by Foundation Fieldbus is possible only if the actuator rotating selector is on the "remote" position.

Conditions which can prevent a command to be executed:

Actuator rotating selector on "local" or "OFF"

Alarm tripped (motor thermal overload)

Emergency command received (ESD)

Actuators controls are located at the Function Block Discrete Output (DO) in the INTELLIBUS module. These controls are:

Function Block DO(1)

Bit n° Value Description

Bit 0 0 No command

1 Close command

Bit 1 0 No command

1 Open command

Bit 2 0 Stop ( or maintained command mode)

1 No stop (or Pulse command mode)

Bit 3 0 No command

1 Auxiliary command 1

Bit 4 0 No command


Bit 5 0 Relay 1 contact open

1 Relay 1 contact closed





Remark: If a Function Block is only one bit writable, then use DO(1), DO(2),DO(3) to reach the controls Open, Close and Stop. In other case Function Block DO(1) is sufficient for controls Open,

Close and Stop



12

OPEN / CLOSE (Open and close command)

According to the actuator configuration, it is possible to select a priority to the opening or to the closing command (refer to NR1151). By default there is no priority given to either opening or closing.

Priority can be used to:

Allow to reverse the actuator rotation direction during a manoeuvre without having to use the stop command. In this case, it is necessary to set a priority to the opening or to the closing direction.

Give priority to one or the other rotation direction: if the actuator receives the open and close commands simultaneously and the priority has been given to the opening, the actuator will run the open position.

STOP If this command is maintained at 0 (most common case), the open and close commands have to be maintained. If this command is set to 1, a short duration open / close command pulse is sufficient to drive the valve to the open or closed position. In this case, the stop command (0) can be used to stop the actuator during the travel in its current position.

AUXILIARY COMMANDS

By default, auxiliary command 1 is assigned to local control (actuator selector) inhibited.

By default, auxiliary command 2 is not assigned to a Fieldbus command but to an emergency command (ESD): this command is hardwired (separate wiring) and directly connected to the control box main strip.

These commands depend of actuator configuration (refer to NR1151) and can be assigned to the following functions.

LOCAL / REMOTE Substitutes for the local/remote selector of the actuator and is used to remotely enable either remote control or local control.

LOCAL+REMOTE / REMOTE: same as previous but local and remote control can be enabled simultaneously.

LOCAL COMMAND INHIBIT The local command inhibit is remotely controlled. It inhibits the local opening and closing commands, and enables remote commands, even if the Local/Remote selector of the actuator is set to Local.

OPEN, CLOSE INHIBIT: this command is used to inhibit opening or closing of the actuator.

AUTO/ON-OFF For an actuator used in modulation with positioner function, it is possible to issue remote commands via proportional control (equivalent to 4-20mA) or via opening/closing/stop commands. The auto/on-off command is used to switch over from one type of command to another.

ESD CLOSE, OPEN, STOP The ESD (Emergency Shut Down) is an emergency remote command, which overrides all other commands. According to the valve operation, the emergency command will be an opening, closing or intermediate stop. This ESD command is assigned to a Fieldbus command for auxiliary command 1 and assigned to a hardwired (separate wiring) for auxiliary command 2.

Note: The hardwired ESD has a higher priority than Fieldbus ESD. The emergency command is not possible when the Local/Remote selector is set to "OFF".

PARTIAL STROKE This command performs automatically a test to confirm that the actuator is still operational. The test consists to operate the actuator on a partial stroke and return. The start position and the stroke % can be configured. An alarm is emitted if the stroke is not performed in a predetermined delay. This delay is worked out from the rated operating time.

RELAYS The relays could be used to have an output indication (wired as a non fieldbus actuator) or to drive outside devices through Fieldbus. These optional relays could be configured in Intelli+ menu for actuator indication or output controls.

7. FUNCTION BLOCK PID

The Function Block PID is used to achieve a Proportional/Integral/Derivative control loop. Function Blocks can be built into fieldbus devices as needed to achieve the desired device functionality. For example, a simple temperature transmitter may contain an AI function block.

The control valve actuator might contain a PID function block as well as the expected AO block. Thus a complete control loop can be built using only a simple transmitter and a control valve actuator. This function block PID is located in the actuator but is operational only if the links with others function blocks (inside or outside the actuator) have been achieved with a Foundation Fieldbus configurator.

The PID located inside the actuator is not obliged to drive it. It could be used to drive another device.
