Feedback data record
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 via a separate data record 197 V2.0. The feedback data record is
only processed with configured configuration control; otherwise it is rejected.

Explanation
Header
Control element
Contains information on which module
is inserted in which slot.
The value that you need to enter in the
corresponding byte depends on the
following rule:
If the module is included in the
•
station option, enter the slot num-
ber of the module from the station
master.
If the slot in the station master is
•
not allocated (e.g. empty slots as
part of combined operation), then
enter the slot number of the module
+ 128.
(Example: module as empty slot on
slot 3: Enter 131 in the control ele-
ment.)
If the module does not exist in the
•
station option, enter 0.
