Parameter Data Record - Siemens SIMATIC S7-1500 Manual

Parameter data record

Parameter assignment in the user program
You have the option to re-parameterize the power supply module in RUN mode of CPU.
Changing parameters in RUN mode
The parameters of the power supply module are in data record 0. Using the instruction
WRREC the adjustable parameters can be transferred to the power supply module. The
parameters assigned in STEP 7 are not changed permanently in the CPU, which means the
parameters assigned in STEP 7 are valid again after a restart.
Output parameter RET_VAL
The power supply module ignores errors that occur during transfer of parameters with the
WRREC instruction and continues operation with the previous parameter assignment.
However, a corresponding error code is written to the RET_VAL output parameter. If no error
occurs, the length of the data actually transferred is entered in RET_VAL.
RET_VAL is 4 bytes long and structured as follows:
● Byte1: Function_Num, general error code
● Byte2: Error_Decode, location of the error detection
● Byte3: Error_Code_1, error detection
● Byte4: Error_Code_2, manufacturer-specific expansion of the error detection
The description of the WRREC instruction and the general error codes are available in the
STEP 7 online help.
Module-specific errors are displayed by means of Error_Code_1 = 224
Error_Code_1 = 225
Manufacturer-specific expansions of the error detection of the WRREC instruction have the
following meaning:
