Examples Of Configuration Control - Siemens SIMATIC S7-1500/ET 200MP System Manual

Note
The data in the feedback data record is always mapped for all modules. In a Shared Device
configuration, it is therefore irrelevant which IO controller the respective modules are
assigned to.
As long as no control data record was sent, a one-to-one module assignment is assumed for
the compilation of data record 197 (station master → station option).
Error messages
In the case of an error when reading the feedback data record, the RDREC instruction returns
the following error messages via the STATUS block parameter:

Examples of configuration control

A station master consisting of a system power supply, CPU, and three I/O modules is
configured in STEP 7 in the following section.
The module at slot 3 is not present in the station option 1 and is "hidden" by the
configuration control.
In station option 2, the order of the modules in slots 3 and 4 is interchanged. The modified
order of the modules is made known to the CPU by a modified control data record.
