4. Example Project

4.1 Plant DescriptionLiquid is fed into a heating boiler through an inlet (Inflow_On).When the boiler is full, the heater switches on (Heating_On)and the liquid is heated. As soon as the liquid reaches thepreset temperature, the heater switches off and the liquiddrains out (Outflow_On). When the level of the liquid reaches

a lower limit value, the drain valve is closed and new liquid isfed in. The process can be shut down using the "OFF" switch.The heater switches off and the valves close when the "OFF"switch is pressed.

4.3 Selecting the Devices

When the type and number of the process data required in the

example project has been determined, you can select theINTERBUS devices.

The process data descriptions "Heating_On", "Inflow_On","Outflow_On" are defined on a DO device. You need twoinputs from an AI device for the process data descriptions"Liquidlevel" and "Temperature". The process data

description "Off" requires one input from a DI device.Select the following four INTERBUS devices for the exampleproject:

Digital input module with at least one input such as:IB ST 24 BDI 8/4 orIB ST 24 DI 16/4

Digital output module with at least three outputs such as:IB ST 24 BDO 8/3 orIB ST 24 DO 16/3

Analog input module with at least two inputs such as:IB ST 24 AI 4/SF orIB ST 24 AI 4/SF4

BK (bus terminal) module for connecting the ST (smartterminal) modules to the remote bus.IBS ST 24 BK-TIBS ST 24 BKM-T

37/58

5228E 35

12. Process Data Descriptions/Signal Paths

By linking the devices with inputs from the device database,you have created process data and signal paths for individualdevices in the process data dialog.

12.1 Process Data Descriptions

When it is linked, every device receives one process datadescription for input process data and one for output processdata. This process data description is long enough to coverfully the process data channel in each case. In order to avoidloading the controller board unnecessarily at runtime, thereshould be as few process data descriptions as possible. You

can only address process data descriptions, and onlyaddressed process data descriptions are transferred to thecontroller board when the parameterization is carried out.

12.2 Signal Paths

Signal paths serve to document your devices and their data.Signal paths are not transferred to the controller board. Thesignal path can be used to identify the features of the signaleven including the position of the terminal on the device. Youcan provide additional information, such as resourceidentification, signal type, purpose etc., for every signal path.

You can compare the information you collect thereby withyour EPLAN system, and have parts of the circuit diagramgenerated automatically.

The process data used in our example project is intended tobe processed in a small program within (process data)preprocessing. This means that you must create process datadescriptions of suitable length, so that you can link themafterwards with the preprocessing variables. Since thenecessary descriptions are already present on the "Signalpaths" tab you can copy them to the "Process Data" tab.


38/58

36 5228E

1. Mark the signal path you want and press +.

2. Switch to the "Process Data" tab and press +.

3. Repeat these steps for all the process data descriptionsthat are necessary for preprocessing.

Figure 33 Standerd process data descriptions

The process data descriptions that are needed are:

Figure 34 Process data descriptions

The available bus configuration need not be identicalwith the bus configuration in the example project. The

devices mentioned must merely be available at anyposition in the bus configuration.


39/58

5228E 37

13. Creating and AssigningVariables

You need variables to create the preprocessing program.Every variable is linked with a process data description andthus forms the interface to the INTERBUS network. Everyvariable which is not linked to a process data description canbe used as a general variable in the preprocessing program.

Figure 35 Context menu "Variables"

1. Select the "Variables" command from the context menu ofthe "Preprocessing" element.

2. Press the key to create a new variable.

3. Enter the following data:

4. Mark the line number of the variable you have justcreated.

5. Press the key to copy the variable.

6. Enter the following data for this variable:

Variable name= " Temperature ",Data type= " INT",Data direction= " I" (Q=output / I=input)

Variable name= " Liquidlevel ",

Data type= " INT",Data direction= " I".


40/58

38 5228E

7. Proceed in the same way until all variables are created asshown below.

14. ProgrammingNow the actual programming begins.

Figure 38 Programming

The Function Block Editor is available for creating thepreprocessing program.

The Function Block Editor is a graphic editor in which you canposition function blocks and functional elements on aworksheet and link them logically with each other.

1. Select the "Programming" command from the contextmenu of the "Preprocessing" element. This starts thegraphic Function Block Editor.

A toolbar appears at the top of the screen when thewindow is open. If the toolbar is not visible you candisplay it with the menu item "Layout... Toolbar... TwoRows".

14.1 Inserting a Block1. Click the center of the worksheet with the mouse.

2. A cursor in the form of a cross appears at the clickedposition.

14.3 Linkage with Variables

Now the two negated inputs are linked with input variables.

1. Mark the top input.2. Click the "Variables" button.

Press this button after marking an input or output of ablock to allocate a variable.

3. Select the "Outflow_On" variable from the "VariableName" selection box.

Figure 44 Select variables

4. Confirm with "Select".

5. Repeat this procedure to link the second input with the"Inflow_On" variable.

If you have selected the "Connect" function, the mousepointer looks like this:

Figure 46 Connect blocks

3. Mark the output of the first AND block.

If you now move the mouse pointer, you will see a line runningfrom the output of the block to the tip of the mouse pointer.Every time you click the mouse you can bend this line by 90 ° at any position on the worksheet.

4. In this way connect the output of the first block with theinput of the second block.

This enables you to create the rest of the application programyourself.

You will find the finished preprocessing program on the nextpage.

15. CompilingAfter you have created the preprocessing program, you canhave it compiled for the controller board.

With this button, you start the compiling process for theentire preprocessing.

1. Select the "Compile All" command from the "Make" menuor click the "Compile All" button.

Figure 48 Compile

2. Should an error occur, please check all program parts andsettings. Make the appropriate corrections and recompile.

The compiling process should run error-free if you havefollowed all the instructions correctly. The project is then

complete and can be transferred to the controller board.

16. Executing Parameterization andDownload

The application program can then be transferred to thecontroller board and started there. For this it is necessary tochange to IBS CMD G4 and to execute the parameterizationthere. Since the link between variables and process datadescriptions is not yet known to the controller board, this mustbe done from IBS CMD G4.

1. Select the "Back to CMD" command from the "File" menu.2. Click the "Controller Board" element with the left mouse

button. This is then marked.

3. Press the right mouse button to open the context menu ofthe "Controller Board" element.

4. Select the "Parameterization" menu item from the contextmenu and the "Execute" menu item from the sub-menu.

Figure 49 Execute parameterization

5. Select the entry "Startup with Preprocessing" from theselection box in the following dialog box and confirm theselection with "OK".

Figure 50 Startup with preprocessing

The parameterization made in IBS CMD G4 is then

transferred to the controller board and the bus cycles arestarted. All newly created process data descriptions and theirlinkage with the variables are then known to the controllerboard. In addition, the preprocessing program is compiled,transferred to the controller board and also started.

17. Testing the Application ProgramYou have the possibility of observing the process data statesonline within the preprocessing program. This is particularlyhelpful for finding and eliminating errors in the program.

1. Select the "Monitoring" command from the context menuof the "Preprocessing" element.

Since you must be in "Monitoring" operating mode in order to

monitor preprocessing, IBS CMD G4 automatically attemptsto switch to this mode. If you protected the "Monitoring"operating mode with a password in Setup, you must enter thispassword now. If you did not apply password protection, youmust enter the word "MONITOR" at the security prompt whichthen appears.

18. DiagnosticsThe "Diagnostics" operating state shows you the errormessages of the controller board and allocates the messagesto individual devices as far as possible. The diagnostics givesyou information about the transmission quality, helps you tofind errors in the bus system and displays the number ofcorrect and defective cycles.

If you are in the "Configuration (Online)" or "Monitoring"operating state you will be informed of an error or a faultautomatically in the dialog box below.

Figure 53 Bus system messages

In the main diagnostics window you see the bus status, errormessages, and the last current message. From here you canconfigure and operate all diagnostics.

18.1 Message History

To enable registration of error messages of IBS CMD G4 to

be registered, one of the online operating states must be set.This may be the "Configuration (Online)", "Monitoring", or"Diagnostics" operating state. In the "Configuration (Offline)"operating state the controller board messages are notregistered.

1. To generate an error message for the controller board to

IBS CMD G4, provoke an error by cutting off the powersupply at any I/O potential group of an input module.

2. A power failure is displayed as a peripheral fault with the"Bus System Messages" dialog box. Click the "Go toDiagnostics" button with the mouse.

3. The dialog box below appears in which the incoming

messages are listed and can also be printed from here.4. Exit the "Messages (Online)" dialog box with the "Close"

button. You are then in the main diagnostics window.

18.2 Recording Statistics

1. Select the "Record Statistics (Online)..." command from

the "Statistics" menu.2. In the dialog box which appears you get information about

the number of INTERBUS cycles, error frequency, anderror location as well as about the transmission quality.You can assign a comment and save the statistics in a file.

3. Observe how the number of cycles increases and

interrupt the power supply a few times to generate othererrors.

4. You will notice how the transmission quality deterioratesas a result of the increased error frequency.

Figure 56 Transmission statistics

The "Transmission Quality" display only provides avaluable statement after a few thousand bus cycles!You can estimate the transmission quality shortly afterstarting the INTERBUS network from the display of"faulty cycles".
