Parameter assignment

Parameter assignment in the user program
You can reconfigure individual channels of the I/O module in RUN without affecting the other
channels.
Changing parameters in RUN
The "WRREC" instruction is used to transfer the parameters to the module using data record
128. In the process the parameters set with STEP 7 are not modified in the CPU, meaning
that after a start the parameters set with STEP 7 are valid again.
STATUS output parameter
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.
Error_ Error_ Cause
Code_1 Code_2
0xB0 0x00 Number of the data record unknown
0xB1 0x01 Length of the data record is incorrect
0xB2 variable Module cannot be reached
0xE0 0x01 Incorrect version in header
0xE0 0x02 Header error (number or length of parameter block)
