Parameter data records
A
A.1
Configuration via parameter data records
The parameter data records of the module have an identical structure, regardless of whether
you configure the module with PROFIBUS DP or PROFINET IO.
Parameter assignment in the user program
You can reassign the module parameters in RUN mode, for example change the diagnostics
behavior, define new limits or configure a modified user data mapping.
Changing parameters in RUN
The "WRREC" instruction is used to transfer the parameters to the module via the respective
data record. The parameters set in STEP 7 do not change in the CPU, which means the
parameters set in STEP 7 are still valid after a restart.
If you reconfigure a module (so that the user data size changes) and diagnostics are pending
prior to the reconfiguration, these diagnostics are not signaled as "outgoing".
STATUS output parameter
If errors occur during the transfer of 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.
The description of the WRREC instruction and the error codes is available in the STEP 7
online help.
