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.

Parameter data records B.1 Parameter assignment and structure of the parameter data records Data record structure The example in the following figure shows the structure of data record 0 for channel 0. The structure of channels 1 to 15 is identical. The values in byte 0 and byte 1 are fixed and may not be changed.
