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

A.2

Parameter assignment and structure of parameter data record

The data record 128 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
change the parameter assignment of the module in your user program regardless of its
configuration. This means that you can use all the functions of the module even if you
configured it using PROFIBUS GSD.
With data records 0 to 7, you can configure the individual channels.
Parameter assignment in the user program
You can change the parameters of the module in RUN (e.g. switch diagnostics on can be
changed in RUN).
Changing parameters in RUN
The "WRREC" instruction is used to transfer the parameters to the module using data record
128 or data records 0 to 7. The parameters set with STEP 7 will not be changed on the CPU,
which means that the parameters set in STEP 7 will be valid again after a restart.
If you reconfigure a module and diagnostics are pending prior to the reconfiguration, these
diagnostics are not signaled as "outgoing".
Output parameter STATUS
If errors occur when transferring parameters with the "WRREC" instruction, the module
continues operation with the previous parameter assignment. However, a corresponding
error code is written to the STATUS output parameter.
You will find a description of the "WRREC" instruction and the error codes in the STEP 7
online help.
