1.9.2 Organisation function blocks
Inputs and outputs of the organisation function blocks
When parameterisation function blocks are used, type …_PRM_INIT function blocks control access to the
I/O data. Data is exchanged via the Festo Parameter Channel (FPC).
..._PRM_... parameterisation function blocks always require an instance of the ..._PRM_INIT
organisation function block.
The following table contains a list of the outputs and inputs of an organisation function block.
Key:
–
Input/output: Designation of an input or output from the CoDeSys function block ..._PRM_INIT.
–
Type: Data type expected by the relevant input or issued at an output.
–
Description: Name and brief description of the CoDeSys function block (0 = FALSE, 1 = TRUE).
Input/output Type Description
FB_CFG WORD FB configuration
Bit 0 = FALSE: Low byte first
Bit 0 = TRUE: High byte first
Bit 1 = Reserved
etc.
Bit 31 = Reserved
DATA_REF VAR_IN_OUT FPC data structure of data type FHPP_PRM_REF
Contents of the data structure are identical to the I/O
data of the FPC
b_FPC_In VAR_IN_OUT FHPP FPC input data
First address of the CAN input data of the FPC (output
data of the motor controller)
b_FPC_Out VAR_IN_OUT FHPP FPC output data
First address of the CAN output data of the FPC (input
data of the motor controller)
