Many actuators and other devices can be connected on a single or redundant fieldbus line provided they are all equipped with a compatible Profibus interface. The Profibus DPV1 interface described in this document has been specially designed for the Bernard actuators with INTELLI+ control. This interface is compliant with Profibus DP (V0) and Profibus DPV1. Profibus DP (V0) runs cyclic communication when Profibus DPV1 runs in addition acyclic messages. Redundant communication The redundant version is specially interesting to ensure a communication continuity even if one line disrupted or if one interface board is out of order for any reason. In case of a redundant fieldbus, the PLC must be able to manage 2 fieldbus lines. Two Profibus interface boards are built in the actuator with isolated connections to the Profibus lines. In case of failure along a line, the PLC can still communicate through the other line. Redundancy is also available with specific monitoring «RedCom with redundancy extensions» that can be used if the PLC can support the same extensions. According to the fieldbus version required an INTELLIBUS, single or redundant line, may equip the actuator. Control box with inside Profibus DP 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 interface. As far as actuators with INTEGRAL+, POSIGAM+ or MODUGAM+ controls are concerned, please refer to the Profibus DP for INTEGRAL+ instructions for start-up (NR1148). 2

FPX: INTELLI+ explosion proof box Display Connection box INTELLIBUS board INTELLI+ board Button for local control 3

4 FPI: INTELLI+ water proof box Display Connection box INTELLIBUS board INTELLI+ board 3.2 CABLE TYPE Button for local control Use exclusively special PROFIBUS cable conforms to the EN standard and of type A. Nominal impedance 135 to 165 Ohm at a frequency of 3 to 20 Mhz. Nominal capacitance between conductors of a pair <30pF /m Cable diameter > 0.64mm Cross section > 0.34mm2 corresponds to AWG 22 Resistance < 110 ohm /km Type shield: Copper shielding braid or braid and foil Example of an armoured cable (galvanised steel wire armor serve), 1 pair Profibus cable, 22AWG: Belden ref 3079ALS ( Profibus cable has to be separated from the other cables with a distance of at least 20cm. It will use a specific cable path and be connected to the earth. It is also necessary to check that all actuators are at the same earth electrical potential. 3.3 FIELDBUS CONNECTION Junction box terminals: A (green wire), B (red wire): Profibus line Shield: Cable shielding Single line Redundant line (option) S A B A B S Single line Redundant line (option) S A B A B S Previous actuator Shield actuator Next actuator Previous actuator Shield End of line actuator The connection depends of actuator type. Refer to the actuator wiring diagram 4

5 End of line termination A termination has to be installed at each end of line. To ease user s job, this termination is built in the connection box. This termination is done through links in the terminal compartment. In case of a redundant version, a termination is connected for both channels. 3.4 SET-UP The INTELLIBUS module is only acting as a Profibus slave. The default setting address is 02. To change this address, use the local control button of the actuator. (refer: NR1151). In the menu select Change then select Fieldbus then select Slave Nr. With the blue button modify the address. Confirm OK with the red button. To save, select return in each submenu until to read: RETURN (Change OK?) Confirm OK with the red button. Other configuration: Lost communication: In case of loss of communication the actuator operates to the close position, open position or stays in position. The default setting is stayput. Also in case of loss of communication all controls are reset. For example if the auxiliary control AUX1 is configured «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. Single channel No data exchange (empty square) BUS Data exchange (rotating triangle) Intellibus module fault (blinking cross) BUS BUS Redundant channel No data exchange (empty square) Channel 1 is primary and on data 1 exchange (rotating triangle). Channel 2 is backup and on data exchange (alternative up and down triangle). Channel 1: Intellibus module fault (blinking cross) Channel 2 is primary and on data exchange (rotating triangle)

6 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. Single line 3.7 PROFIBUS DP ARCHITECTURE The Profibus cable coming from the PLC is connected to the first actuator then the Profibus 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. To avoid reduced performance in transmission don t add ramifications on the line PLC Note:The PLC is also at the end of the line and needs a termination No ramifications To make a detour use 2 cables, up and down. End of line actuator Termination is «on» Maximum line length is 1200m (3600ft). Maximum number of actuators by line is 31. Maximum line length is reduced according to the communication speed: Transmission baud rate < kbit/s kbit/s 500 kbit/s 1,5 MBit/s Maximum line length 1200m 1000m 400m 200m An end of line termination must be connected at each end of line actuator. (see 3.3) Repeaters Adding repeaters modules allows to increase both the number of actuator on the line and total line length. Each repeater uses one connection point therefore this limits the number of actuators by segment to 30 units and allows to lengthen the line by 1000m. According to the type of repeater, it is possible to use until 9 repeaters and to extend the line as long as 10 km. Maximum number of actuators depends of PLC capacity, addressing capacity and number of segment with repeaters. The maximum on one Profibus line is 124. 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. Repeater power supply PLC Segment 1000m long 30 actuators Repeater Segment 1200m long 31 actuators 6

7 Repeaters can also be used to get additional fieldbus lines at a low cost if placed at PLC output. Each line is independent from the others and therefore a problem on a line does not affect the others. BERNARD CONTROLS can supply weatherproof or explosion proof repeaters. Repeater PLC Redundancy Repeater Redundancy of the fieldbus system is to continue to communicate with the actuators even if a line fails. In order to achieve this function all the communication system is doubled. The PLC uses two output Profibus ports, the fieldbus line is doubled and the actuator interface board is doubled. If repeaters are required, the repeaters are doubled. The redundant INTELLIBUS module is designed according to Profibus Guide Line «Specification Slave Redundancy» N 2212, that includes a redundancy communication channel (RedCom) and special redundancy extensions. One of the slave module acts as primary and the other one as backup. In fact the Profibus system allows different level of redundancy: Flying redundancy is a redundancy of the connection point, the actuator interface is doubled and also the PLC interface. The line (Profibus cable) is a single line. The redundant actuator interface INTELLIBUS has 2 channels, each one is connected to the Profibus line. The address is not the same for each channel. One address is chosen from 1 to 125, the other one is this address Redundant PLC Primary PLC Single line Redundant INTELLIBUS Redundant INTELLIBUS Backup PLC System redundancy is the most common system with all communication system doubled as described first. Redundant PLC PLC Master 1 Redundant line Redundant INTELLIBUS Redundant INTELLIBUS PLC Master 2 7

8 For one actuator the address is the same on both lines. When the actuator is powered on, the INTELLIBUS module tries to get the communication on a first line and toggles between both lines until to find the communication. It is the INTELLIBUS module that decides to communicate with one line or the other. Like this, all the actuators are not obliged communicating one the same line and both lines are working simultaneously. There is not a main line and a backup line, each line has the same level. On the other hand the actuator interface has a primary channel (the one that got a data exchange state) and a backup channel. Information supplied by the primary or the backup channel: - This channel (or slave) is primary or this channel is backup - 2 channels available or only one. - FR mode (Flying redundancy) or SR mode (System redundancy). See details at «Command and Signalling» Redundancy management must be performed by the PLC. To manage the line redundancy a PLC could be used with different level of equipment. - One PLC with 2 Profibus DPV1 Interface. For example a CPU DP from Siemens that includes 2 Profibus DPV1 interfaces. The PLC is single and interface is doubled. PLC should be programmed to manage the redundancy. If the PLC doesn t support the special redundancy extensions of the Profibus Guide Line «Slave redundancy» then INTELLIBUS module will be used as a classical redundancy. To do that there is to load in the PLC the appropriate GSD file for classical redundancy: LBVR0ACC.GSD - Two PLC with each a Profibus DPV1 interface. A link between both PLC through an auxiliary communication port allows the redundancy monitoring. Example 2 CPU DP from Siemens. PLC should be programmed to manage the redundancy. If the PLC doesn t support the special redundancy extensions of the Profibus Guide Line «Slave Redundancy» then INTELLIBUS module will be used as a classical redundancy. To do that there is to load in the PLC the appropriate GSD file for classical redundancy: LBVR0ACC.GSD - Two PLC fault tolerant like the CPU 414 H from Siemens and optic fibre between them. In that case no programming is necessary to manage the redundancy. This PLC supports the special redundancy extensions. The INTELLIBUS module will be used with RedCom and extensions, and to do that there is to load the appropriate GSD file in the PLC : LBRE0ACC.GSD. 4 CONTROLS AND INDICATIONS The Profibus DPV1 system has a cyclic communication (compatible with Profibus DP) and acyclic communication. The cyclic communication is mainly use for the Process. Data are read and written in a well-defined timing. The useful data are selected in the list below and transmitted in a cyclic way. The selection of only a few data also increases the communication speed. The acyclic communication is mainly use for maintenance. The data are collected only on request that avoid to reduce the cyclic communication speed. See below «5 Acyclic communication» 4.1 CONTROLS Valve control by the Profibus 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) 8

9 Control byte description Actuators controls are located at the addresses 0 to 4 on the INTELLIBUS module. These controls are: Address 0: ON-OFF control 0 NO COMMAND Bit 0 1 OPEN COMMAND 0 NO COMMAND Bit 1 1 CLOSE COMMAND 0 STOP ( OR MAINTAINED COMMAND MODE) Bit 2 1 NO STOP (OR PULSE COMMAND MODE) Bit 3 to 7 - NOT USED 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. Address 1: Auxiliary commands 0 NO COMMAND Bit 0 1 AUXILIARY COMMAND 1 0 NO COMMAND Bit 1 1 AUXILIARY COMMAND 2 Bit 2 to 7 - NOT USED By default, auxiliary command 1 is assigned to local control (actuator selector) inhibited. By default, auxiliary command 2 is not assigned to a Profibus 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. 9

10 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 definition as above, but local and remote control can be enabled simultaneously. LOCAL COMMAND INHIBIT: the local command inhibit is remotely controlled. This command 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 Profibus 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 Profibus 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. Address 2 and 3 : Proportional control (set-point) Address 2 Bit 0 to 7 MSB Increment 0.1%. Range 0 to Bit 0 to 7 LSB 0= closed, 1000= open. To choose between proportional and ON-OFF control, assign an auxiliary command to the function AUTO/ ON-OFF then select the control mode required from the control room (see above Address 1). Address 4 : Relay output (option) 0 RELAY 1 CONTACT OPEN Bit 0 1 RELAY 1 CONTACT CLOSED 0 RELAY 2 CONTACT OPEN Bit 1 1 RELAY 2 CONTACT CLOSED 0 RELAY 3 CONTACT OPEN Bit 2 1 RELAY 3 CONTACT CLOSED 0 RELAY 4 CONTACT OPEN Bit 3 1 RELAY 4 CONTACT CLOSED 0 RELAY 5 CONTACT OPEN Bit 4 1 RELAY 5 CONTACT CLOSED 0 RELAY 6 CONTACT OPEN Bit 5 1 RELAY 6 CONTACT CLOSED 0 RELAY 7 CONTACT OPEN Bit 6 1 RELAY 7 CONTACT CLOSED Bit 7 NOT USED 10

11 The relays could be used to have an output indication (wired as a non fieldbus actuator) or to drive outside devices through Profibus. These optional relays could be configured in Intelli+ menu for actuator indication or output controls. 4.2 ACTUATOR FEEDBACK INDICATION indication byte description The first five words of the INTELLIBUS give the actuator status.

18 5 ACYCLIC COMMUNICATION The INTELLIBUS supports acyclic communication (extension V1 of the Profibus protocol) which allows to read the actuator s state, to read all its configuration. It can be also reconfigured through the V1 extension. There is two type of master in the acyclic communication: - The master class1 which supports cyclic communication. It is normally the same PLC which manages the actuators. - The master class2 supports all the acyclic communication. It can be included to Profibus without interference. A laptop equipped with a Profibus module and PDM software may be used as a master class2 anywhere on the line. The INTELLIBUS supports the Read and Write messages of the master class1 (MSAC1_Read, MSAC1_Write). For master class 2, this interface supports Initiate, Abort, Read and Write services. Interface board supports a maximum of 2 simultaneous class2 master connections. We advise to use PDM Siemens software to read and configurate the actuators with a master class2. We can give you an Electronic Device Description (EDD) which allows you to manage our actuators with PDM. With PDM and this EDD you can configure and parameterise the actuators and also recover information for diagnostics and maintenance. For example, alarms, activity, torque curves To use PDM, not straight to the fieldbus but above the PLC then the PLC must be Siemens S7 400 series. In case of a redundant system, the connection of PDM to one fieldbus line, will collect all data including those communicating on the other line. PDM PDM Ethernet PLC Profibus DPV1 18
