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 "WRREC" instruction is used to transfer the parameters to the module using data record 128.
Output parameter STATUS
If errors occur when transferring parameters with the "WRREC" instruction, the module
continues operation with the previous parameter assignment. The STATUS output parameter
contains a 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.
