4.2 Calling the function block
Procedure
Proceed as follows to work with the _ET200S_FC_control function block in your user project
(the numbers shown in the following program segment correspond to the steps listed below):
1. Create an instance of the function block.
2. Call instance of the function block.
3. Transfer input parameters.
4. The output parameters of the function block are accessed with <instance name of
FB>.<name of output parameter>.
5. The data for the I/O outputs prepared by the FB are assigned to the I/O variables.
Note
The program segment is an extract from the supplied application example. The application
example is included on the "SIMOTION Utilities & Applications" CD-ROM and is available
for various SIMOTION hardware platforms.
The "SIMOTION Utilities & Applications" CD-ROM is provided free of charge with
SIMOTION SCOUT.
If you want to control several frequency converters, you must create a new variable for the
FB instances with a new name for each module used.
Separate data structures have been created for the input and output parameters in the
example to provide a better overview.
