Feedback data record of the ET 200MP distributed I/O system

Operating principle
The feedback data record informs you about the accuracy of the module assignment and
gives you the option of detecting assignment errors in the control data record. The feedback
data record is mapped by means of a separate data record 197.
Slot assignment
The feedback data record exists only when configuration control is configured and always
refers to the maximum quantity framework without interface module, i.e., 31 slots.
The following table shows the slot assignment of the modules:
