Parameter assignment in the user program
The module parameters can be assigned in RUN (for example, measuring ranges of
selected channels can be edited in RUN without having an effect on the other channels).
Parameter assignment in RUN
Instruction WRREC is used to transfer the parameters by means of data records 0 to 7 and
8. The parameters set in STEP 7 do not change in the CPU, which means the parameters
set in STEP 7 are still valid after a restart.
The parameters are only checked for plausibility by the module after the transfer to the
module.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 is available in the STEP 7
online help.
Operation of the module behind a PROFIBUS DP interface module
If the module is operated behind a PROFIBUS DP interface module, the parameter data
records 0 and 1 are not read back. You obtain the diagnostics data records 0 and 1 with the
read back parameter data records 0 and 1. You can find additional information in the
Interrupts section of the manual for the PROFIBUS DP interface module on the The parameters in data records 0 to 7 and in data record 8 are available for 1x 8-channel
configuration and are assigned as follows:
● Data record 0 for channel 0
● Data record 1 for channel 1
