Parameter Data Records; Parameter Assignment And Structure Of The Parameter Data Records - Siemens SIMATIC S7-1500 Equipment Manual

Parameter data records

B.1 Parameter assignment and structure of the parameter data
records
The data records of the module have an identical structure, regardless of whether you
configure the module with PROFIBUS DP or PROFINET IO.
Dependencies for configuration with GSD file
When a GSD file is used to configure a module, dependencies can arise when "assigning the
parameters".
There are no dependencies for this module. You can assign the individual parameters in any
combination.
Parameter assignment in the user program
You have the option to reconfigure the module in RUN (e.g. the response of selected
channels to the CPU STOP state can be changed in RUN without 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 records 64
to 79. The parameters set in STEP 7 are not changed in the CPU, which means the parameters
set in STEP 7 are valid again after a restart.
The parameters are only checked for plausibility by the module after the transfer.
STATUS output parameter
The module ignores errors that occurred during the transfer of parameters with the WRREC
instruction and 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.
Operation of the module behind a PROFIBUS DP interface module
If the module is operated behind a PROFIBUS DP interface module, the parameter data
records 0 and 1 are not read back. You obtain the diagnostics data records 0 and 1 with the
read back parameter data records 0 and 1. You can find more information in the Interrupts
section of the manual for the PROFIBUS DP interface module in the Internet
(http://support.automation.siemens.com/WW/view/en/78324181).
