* Not possible if the slot is marked as not available.
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).
