4 + ((max. slot - 1)× 2) + 1
* 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 has been sent, a one-to-one module assignment is
assumed for the compilation of data record 197 (station master → station option).
