2 Basics2.1 Topology

The IM 153-2 FF interface module is required to integrate an FF segment intoPCS 7. The combination of IM 153-2 FF and FDC 157 (Field Device Coupler) iscalled FF Link. The FF Link is the link or gateway between the higher-levelcommunication system, for example PROFIBUS DP, and the lower-level FFsegment. The following figure shows the FF topologies possible for PCS 7.Figure 2-1

2.2 FF communication

LAS (Link Active Scheduler)For FF, communication (which device is allowed to send data and when) is definedin a schedule and controlled by an LAS-capable device. In normal operation, theFF Link performs this LAS function.

Macro cycleThe macro cycle is the calculated deterministic period required for processing thecyclic and acyclic data of an FF segment.

NOTICE The macro cycle (schedule) changes with each change to the FF segment(e.g., number of devices or data volume).

CommunicationPCS 7 distinguishes between cyclic and acyclic communication. During cyclic(continuous) communication, defined tasks and responses are processed in aspecified period. One example is closed-loop process control in which a measuredvalue, e.g. boiler pressure, is acquired and reduced with the configured logic in theCFC by opening a drain valve.During acyclic communication, in contrast, an action is performed one or moretimes upon request, but not continuously. One example is reading out theparameterization of a field device.

2.3 Certification to Level HOST 61b

SIMATIC PCS 7 V8.1 certified to HOST 61b of Fieldbus Foundation.Based on this certification, SIMATIC PDM V8.2 also supports the followingfunctions of FF field devices: Cross Block references Enhanced Function Blocks Multi Capability Level Dynamic Block Instantiation Profiled Custom Function Blocks Configuration of Scheduled Control Function Blocks DD V5.1 Device-Level Access

2.4 Configuration in HW Config

Integrating the device catalog as described in Chapter 3.1 is the prerequisite forconfiguring FF devices. All devices integrated using the “Device IntegrationManager” can be found in the HW Config device catalog.

2.5 Parameterization in PDM

In general, we recommend that a device be parameterized before integrating it intothe productive sector. This includes the following device parameters: Resource block (device block)

Device- and manufacturer-specific information such as device type, firmware,etc.

Transducer blocksForm the interface between the sensor/actuator and the field device.

Function blocksForm the interface between the field device and the FF bus and containdevice-specific blocks for, e.g., analog (AI / AO) and digital communication (DI/ DO) or closed-loop (PD / PID) and open-loop control functions.

Chapter 4 “Configuration, Project Engineering and Parameter Assignment”describes all the steps necessary for the basic parameterization of a field device.

greater than “0”.14. Set the device-specific parameters for, e.g., analog (AI / AO) and digital

communication (DI / DO) or closed-loop (PD / PID) and open-loop controlfunctions.NoteUse the same factors and settings for measured value and output scaling. In theCFC, you can define scaling for the measured value later in the configurationprocedure.

15. Change the “Linearization type” parameter to direct, indirect or indirect squareroot.

16. The process-relevant limits (alarms and warnings) are not parameterized in thedevice; they are configured centrally for the respective measured value in theCFC and monitored and operated via the OS.NoteFor some devices, it is possible to parameterize maintenance requests. In thiscase, the maintenance request is parameterized if necessary and operated usingPCS 7 Asset Management.

17. To download the parameters and change the mode, follow steps 4 to 7 with therelevant FBs.

18. Follow steps 14 to 19 for the remaining FBs to which you have already assignedinput or output addresses in HW Config.NoteThe parameterization of FB2 and FB3 in PDM allows you to use the sensor andelectronics temperature or the measured value in modified form, e.g. in anotherunit of measurement, for the configuration in the CFC.

Note Use “File > Export” to export the parameters of a device. You can use this exportfile for basic parameterization of several identical devices or if replacement isnecessary.

5 Operation of the Application

The following chapters discuss and describe two typical FF scenarios.

5.1 Scenario A – Expanding the project by an FF segment

In this scenario, an existing PCS 7 project is expanded by an FF segment with fivefield devices (using the example of the SITRANS P DS III, SIPART PS2, SITRANSTH400, 3051 pressure transmitter and SITRANS LR250).

PreparationParameterize the field devices as described in Chapter 4.2 “Hardwareconfiguration” and Chapter 4.3 “Device parameterization with SIMATIC PDM” andensure that the names and addresses of the following configuration list are correct.Table 5-1

Plant Device Name Address

1. RMT1 SITRANS P DS III PT111 212. RMT1 3051 PT112 223. RMT1 SITRANS TH400 TT111 234. RMT1 SIPART PS2 VP111 245. RMT1 SITRANS LR250 LT111 25

To check the segment configuration (electrical quantities of the segment andquantity framework), the FF segment is calculated using the SIMATIC FieldbusCalculator. In addition, the user data volume for the FF segment is considered.

Note The SIMATIC Fieldbus Calculator is available as an application example, EntryID 53842953.

The following configuration is used to check the segment.Figure 5-1

Checking the cyclic data volume and the segment configurationTo check the user data volume (value and status), one measured value is assumedfor each device.Table 5-2

Segment Number offield devices

User data volume(5 bytes per device)

FF-1 5 25 bytes

The number of field devices of the example corresponds to a smaller FFconfiguration. The small number of devices and user data volume results in thefollowing advantages: The segment can be extended by additional devices. A fast macro cycle can be implemented. Additional measured values of existing devices can be additionally configured

in HW Config. The FF segment can be extended by CiF closed-loop controls and

interconnections.The figure below shows the calculation and evaluation of the electrical quantities ofthe FF segment in the SIMATIC Fieldbus Calculator.Figure 5-2

The evaluation of the data entered provides you with the information that theconfiguration can be operated with the quantity framework and line lengths.

Configuring the hardwareIn order to proceed, the device parameterization and hardware addressing of theFF Link must have been completed.Table 5-3

Action

1. Go to HW Config and in the hardware device catalog (profile: PCS7_V80) in thePROFIBUS DP tree, select the FF Link (IM 153-2 FF). Add the FF Link to thePROFIBUS DP segment.NoteThe configured address must match the physical address of the FF Link.

2. Select the FF Link and open the Object Properties of the FDC 157. In the ObjectProperties, select the “Parameters” tab and set your FDC 157 configuration.

You can choose between the following configurations: No redundant configuration Coupler redundancy Ring redundancy

3. By selecting the FF bus cable, you can adjust the preset bus profile for the FFsegment.NoteChange bus profile parameters only if you have enough fieldbus knowledge and ifchanges are necessary. Incorrect bus parameters can cause malfunctions on theFF segment. For more information, please refer to the “SIMATIC Process ControlSystem PCS 7 FOUNDATION Fieldbus” commissioning manual, Chapter “Busparameters”, Entry ID 70235901.

Actionobject names from your configuration list.NoteThe assignment is not necessary if the object names and addresses of the HWConfig object are identical with the device information in the LifeList.For instructions for assigning field devices to HW Config objects, please refer toChapter 4.2 “Hardware configuration”.

11. Repeat step 4 for each device of the FF segment until you have assigned alldevices.NoteIf you are sure that there will be no address conflict, you can simultaneouslyconnect all devices to one FF segment. Then assign each device to an HWConfig object.

12. For the FBs to be configured, assign an I/O address (input or output address) toeach device.NoteWhen addressing multiple device FBs in HW Config, parameterize the same FBsfor the respective device also in SIMATIC PDM.

13. Assign a symbolic name to each input and output address. To do so, select theaddress and in the context menu, select “Edit symbols…”.

14. In the next window, enter a device-specific name, e.g. for a pressure transmitterfor the measured value (e.g., PT111_PV) and the associated measured valuestatus (PT111_QC). The abbreviation “PV” means primary value and “QC” standsfor quality code. Select “OK” or “Apply” to apply the entries.NoteFor the names of the devices, please refer to the plant’s planning documents andderive the symbolic names from them.

15. Select the FF subsystem and in the context menu, select “Object Properties…”.16. In the FF subsystem object properties, select the “Properties” button.17. In the next window, select the “Macro cycle” tab.18. Select the “Calculate schedule” button and check if the values meet your project

requirements (also in graphical form). Customize the macro cycle to yourrequirements and schedule a reserve for future extensions.NoteThe following changes require macro cycle calculations: Number of devices on the FF segment Device FB configuration Interconnections in the Connection Editor

19. Select the “Station > Save and Compile” menu option to compile the entirehardware configuration.

20. Select the “PLC > Download to Module…” menu option to download theconfiguration to the automation system. First the configuration is downloaded tothe automation system. Then the scheduler is transferred to each FF node in theFF segment.

21. Select the FF Link to read out and save the device parameters and in the FF Linkcontext menu, select “SIMATIC PDM > Upload to PC/PG …”. Select the “Objectwith all subordinate objects and networks” option to read out all devices of the FFsegment.NoteAlternatively, you can also open each individual device and read out, check andsave all parameters.

22. Select the FF Link and in the FF Link context menu, select “Object Properties…”.23. In the next window, select the “Load FF segment” tab.24. Select the “Only load FF Link and FF devices when modified” option.

NoteBy selecting this option, an FF segment will only be loaded when configurationchanges are made to the FF segment.

NOTICE The following behavior occurs when loading an FF segment:Loading parameters: When loading the device parameters, the relevantdevice cannot be accessed while loading.Redundant configuration and single CPU: When loading the scheduler, theentire segment cannot be accessed.

CFC configurationThe symbolic names of the input and output addresses for the FBs of the FFdevices are necessary to continue the configuration process.In the CFC, the channel blocks of the Advanced Process Library (APL) are used tointerconnect the hardware (symbolic names). Depending on the signal type, youcan use the following blocks.Table 5-4

Signal type Block name FB number

Analog input FbAnIn FB 1813Analog output FbAnOut FB 1814Digital input FbDiIn FB 1815Digital output FbDiOut FB 1816

The further configuration steps, i.e. interconnecting the channel blocks with, e.g.,measured value display blocks or designing closed-loop controls, are identical withthe configuration for PROFIBUS PA, HART and conventional field devices.

Note For configuring, use the detailed configuring guides, for example:
