Feedback Data Record - Siemens SIPLUS HCS Series Operating Instructions Manual

8.5.3.3

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.
Rules
Observe the following rules:
● The feedback data record refers to the configured station configuration and always
includes the maximum configuration limits, which is 25 modules.
● Partial reading of the feedback data record is not possible.
● As long as a control data record is not sent, it is assumed that no modules are inserted
(DS197 has status "0").
