Preamble 1 Preamble In order to make easier the description, all the variables mentioned in this document are written with the suffix RB or TB or AIFB or PID indicating the block into where the variables are mapped.
FOUNDATION Fieldbus Definition 3 FOUNDATION Fieldbus Definition FOUNDATION™ Fieldbus is an all-digital, serial, two-way communication system that serves as a Local Area Network (LAN) for factory/plant instrumentation and control devices. FOUNDATION™ Fieldbus is designed to be compatible with the officially sanctioned SP50 standards project of the ISA (The International Society for Measurement and Control) and the specifications of the IEC (International Electrotechnical Committee.
Device Introduction 4.2 FOUNDATIONTM Fieldbus Version Considerations The models 265 / 267 / 269 FOUNDATIONTM Fieldbus version differs by the traditional 4 … 20 mA version only in the secondary electronic and in the Terminal block. The transducer with its own primary electronic has to be considered the common part of all the different Transmitter versions (HART, PROFIBUS and FF). This feature offers the possibility to replace on the same transmitters different electronics with the plug and play capability.
Device Introduction - LAS Functionality With this functionality the models 265 / 267 / 269 FF can acts as backup master, keeping alive the Function block application whenever the Master/Controller fails. The LAS implemented in the device supports 1 sub-schedule, 25 sequences and 25 elements for sequence. - 1 Enhanced Resource Block This block identifies the transmitter and includes characteristics of the instrument connected at the Fieldbus like Model, Serial Number, Manufacturer and so on.
Device Introduction - - FMS services supported: - Initiate - Abort - Status - Identify - Read Variable - Write Variable - Get Object Dictionary Link objects mechanism. This allows the linking between the produced Values or Alarms or Trends in output from the AIFBs (Publisher) with other Input Blocks enabled to receive these information (Subscriber). I.e. Pressure in output from AIFB, linked as input for PIDFB. - Event Notification mechanism.

Hardware Characteristics 5 5.1 Hardware Characteristics Current limitation This electronic implements also an especial circuitry for the current limitation. Whenever a fatal failure occurs and the current consumption increase over the 19 mA, this circuitry provides a limitation of the current to 19 mA, in order to save the good functionality of the other connected devices that otherwise would be switched off due to the missing power available. 5.
Hardware Characteristics 5.3 Local Keys Three external push buttons are available, see the Fig. 2. To make the keys accessible, release the screw and turn the protection cap aside. M00055 Fig. 2: Push Buttons View Simulation: The simulation can be activated as follows (see also symbolism on the plate). 1. First, fully press down the mode key "M" with an appropriate screwdriver. 2. Then turn the switch clockwise by 90° angle.
Hardware Characteristics 5.4 Structure tree The menu is called up using the mode button "M". Important The numbers displayed inversely ( 1 to 9 ) specify the code for the display value. These numbers are shown on the 2nd line of the display, on the left-hand side.

Network Architecture 6 Network Architecture A simple generic FOUNDATIONTM Fieldbus system is represented in Fig. 3. The H1 segment is applicable in Ex and non Ex area. The network can be designed following three different topologies as shown in the Fig. 4 below or can be applied as a mix of the three. Control System Network Controller H1 Termination ?x IEC 1158-2 with 31.25 Kbits/sec IS Barrier Termination PressureTx M00505 Fig.
Network Architecture Junction Box Trunk & Spurs Daisy Chain Tree M00506 Fig. 4: Fieldbus topologies Some summarised Fieldbus characteristics. Parameters Specifications Data rate 31.
Network Architecture The models 265 / 267 / 269 FF have the following power requirements: - Current consumption = 12 mA - Power Supply non-Ex = 10.2 … 32 V DC A typical ABB Solution for FOUNDATION Fieldbus is represented in the Fig. 5. The number of models 265 / 267 / 269 FF transmitters connected on one segment for EEx ia applications can be increased when used in conjunction with the ABB Multibarrier NMB204-EX.
Network Architecture 6.1 Electrical Connections The 2600 FF is a Bus Powered device with FOUNDATION Fieldbus output. On the terminal block, two screws for the BUS CONNECTION are available, see the Fig. 6. The Polarity has not consistency, so the two bus cables can be connected without take care about the polarity. FF + FF M00508 Fig. 6: Terminal Block The special FF connector (gland receptacles) is also available as optional item for the “quick connection” of the transmitter to the bus.
FOUNDATION Fieldbus Overview Approvals 7 FOUNDATION Fieldbus Overview In the Fig. 7, is represented how the Function Blocks inside the FF devices connected on the bus, can be linked together in order to achieve a simple control loop. After the loop has been designed, the LAS Master device located in the Controller or, as back up, in the slave device itself, starts the scheduling of the Function Block executions and of the publisher / subscriber communications in a deterministic way.
FOUNDATION Fieldbus Overview In the Fig. 8 is represented the macro cycle of the above loop. The LAS functionality inside the controller provides to handle the loop, and the macro-cycle is the temporary representation of how, function blocks and communications, are scheduled. From the instant 0 to 20 the AIFB is executed, in the period from 20 to 30 the LAS provide to schedule the AIFB output. The Pressure Transmitter provides to publish the pressure value, the PIDFB subscribes this value.
Initialisation 8 Initialisation At the power up, the 2600T FF executes some internal self-tests. Both the Hardware and the memory contents are checked before to start the normal operations. By default, the Function Blocks of the 2600T FF are not running, until a FB application is not downloaded into the transmitter. After the Function Block has been successfully downloaded into the transmitter, the FB´s start to be scheduled producing an output value to be used for the Process Control.
Device Addressing A 9 Device Addressing When the models 265 / 267 / 269 FF Transmitter are connected on a FF bus, the Master has to recognize them with a unique address in the world. For this reason, the FF specifications define three different addressing levels that characterize the FF devices: - The DEV_ID is the unique device identifier. - The PD_TAG is the physical name of the device. - The Node Address is the real node at which the device is connected on the bus.
Device Configuration K 10 Device Configuration 10.1 Device Description The models 265 / 267 / 269 FF Pressure Transmitter offers a set of variables available trough the FF communication. The Master for configuration and maintenance purposes can access the variables with Read and Write operations each addressed by an Index number.

In this case, check that the L_TYPE is INDIRECT.
