Parameter Data Record; Parameter Assignment And Structure Of The Parameter Data Record - Siemens SIMATIC ET 200SP Equipment Manual

Parameter data record

A.1 Parameter assignment and structure of the parameter data
record
The data record of the module has an identical structure, regardless of whether you configure
the module with PROFIBUS DP or PROFINET IO. With data record 128, you can reconfigure the
module in your user program regardless of your programming. This means that you can use
all the functions of the module even if you configured it via PROFIBUS-GSD.
Parameter assignment in the user program
You can change the parameters of the module in RUN.
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 a corresponding error code.
You will find a description of the "WRREC" instruction and the error codes in the STEP 7 online
help.

Channel 0 includes the diagnostics enable for the entire module.
