Feedback data record
Feedback data record
The feedback data record provides information on the accuracy of the module assignment
and gives you the chance to detect assignment errors in the control data record. The
feedback data record is mapped by a separate data record 197.
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 applies here:
● The power supply (PS) module is inserted in "Slot 0"
before
the interface module
● Starting from "Slot 2", a maximum of 30 modules follow
after
the interface module.
Partial reading of the feedback data record is possible.

Note
The data in the feedback data record are always mapped for all modules. In a Shared
Device configuration it is therefore irrelevant which controller the respective modules are
assigned to.
As long as no control data record was sent, a one
-to-one module ass
ignment is assumed for
the compilation of data record 197 (preset configuration
→ actual configuration).
