Parameter assignment

Parameter assignment in the user program
You can reconfigure individual channels of the module in RUN without this having an effect on
the other channels.
Changing parameters in RUN
The parameters are transferred to the module with the "WRREC" instruction via data record 128.
Output parameter STATUS of the WRREC
If errors occur when transferring parameters with the "WRREC" instruction, the module
continues operation with the previous parameter assignment. The STATUS output parameter
contains the corresponding error code.
The STATUS output parameter is 4 bytes long and is configured as followed:
• Byte1: Function_Num, general error code
• Byte2: Error_Decode, location of the error code
• Byte3: Error_Code_1, error code
• Byte4: Error_Code_2, manufacturer-specific extension of the error code
Module-specific errors are displayed via Error_Decode = 0x80 and Error_Code_1 / Error_Code_2.
Error_ Error_ Cause

0xB0 0x00 Number of the data record unknown
0xB1 0x01 Length of the data record is incorrect
0xB2 0x00 to Module cannot be reached
