Parameter Assignment - Siemens SIMATIC RQ 4x120VDC-230VAC/5A CO HA Manual

A.2

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. The parameters set in STEP 7 are not changed in the CPU, which means that the
parameters set in STEP 7 will be valid again after a restart.
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 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
Code_ Code_
1 2
0xB0 0x00 Number of the data record unknown
0xB1 0x01 Length of the data record is incorrect
0xB2 Varia‐ Module cannot be reached
ble
0xE0 0x01 Wrong version in the header
0xE0 0x02 Header error (number or length of parameter block)
0xE1 0x01 Reserved bit set
0xE1 0x06 Invalid encoding for substitute value reaction
Valid parameters
Only the values specified in the following are permitted. Values that are not listed are rejected
by the module.
