Parameter data records

Parameter assignment and structure of the parameter data records

Parameter assignment in the user program
You have the option to reconfigure the module in RUN (e.g. the input delay values
of selected channels can be edited 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 records
0 to 15. The parameters set in STEP 7 will not be changed in the CPU, which means the
parameters set in STEP 7 will be valid after a restart.
Output parameter STATUS
The module ignores errors that occurred during the transfer of parameters with
the WRREC instruction and continues operation with the previous parameter assignment.
However, a corresponding error code is written to the STATUS output parameter.
The description of the WRREC instruction and the error codes are available in the
STEP 7 online help.
Assignment of data record and channel
The channel parameters of the module are included in data records 0 to 15
and are assigned as follows:
● Data record 0 for channel 0
● Data record 1 for channel 1
● ...
● Data record 14 for channel 14
● Data record 15 for channel 15
