Parameter assignment and structure of the parameter data record
Parameter assignment in the user program
The module parameter settings can be changed in RUN. The time period of selected
channels can, for example, be changed in RUN in the "Pulse width modulation" operating
mode without having an effect on the other channels.
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 the
parameters set in STEP 7 are 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.
STATUS output parameter
The module ignores errors that occur during the transfer of parameters with the "WRREC"
instruction and continues operation with the previous parameter assignment. The STATUS
output parameter contains a corresponding error code.
The description of the "WRREC" instruction and the error codes is available in the STEP 7
online help.
