Combination of configuration control and PROFIenergy (at PROFINET)
You can use configuration control together with PROFIenergy for the ET 200AL distributed I/O
system.
Ensure that you use the slots of the used station option when creating Data record 3. Do not
use the slots configured in the station master.
Example: You want to set up PROFIenergy for a DQ module of an IM 157-1 PN that works
with configuration control. You have configured the DQ module to Slot 5 in the station
master. You have moved the DQ module to Slot 2 in the station option. In order to set up
PROFIenergy for this module use Slot 2 in Data record 3.
You can find more information about PROFIenergy in the Interface module IM 157-1 PN

7.3.3 Feedback data record at the ET200AL 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 via a separate data record 197 V2.0.
Feedback data record
The feedback data record exists only when configuration control is configured and always
refers to the maximum configuration limits without interface module, i.e., 34 slots. Partial
reading of the feedback data record is possible.
