Parameter data records
A.1
Parameter assignment and structure of parameter data record for
DI operating mode
Parameter assignment in the user program
You can change the parameters of the module in RUN.
Changing parameters in RUN
The "WRREC" instruction is used to transfer the parameters to the module using data
record 128. The parameters set in STEP 7 are not changed in the CPU, which means that
the parameters set in STEP 7 will be valid again after a restart.
Note
Changing parameters in RUN
A parameter data record that has content different from the startup parameter assignment
can result in a brief exit from clocked mode and renewed synchronization with the fieldbus
cycle.
Output parameter STATUS
If errors occur when transferring parameters with the "WRREC" instruction, the module
continues operation with the previous parameter assignment. The STATUS output
parameter contains a corresponding error code.
You can find a description of the "WRREC" instruction and the error codes in the STEP 7
online help.
