QUESTION:
Can I view a comparer that I have used in a network monitored with S7-PDIAG or in S7-GRAPH increments in the diagnostics images in KOP or STL in case of a failure?

ANSWER:
The comparers (CMP-Box) are displayed as "L0.0" (comparer set) in ProAgent.

Excerpts from the online help of S7-GRAPH: Analysis with O & M devices

• Certain options packs for O & M devices allow a analysis of S7-GRAPH errors. Conditions with normally open or closed contacts can by analyzed. When using comparers, the address (=comparer set) "L0.0" is displayed. Unknown addresses are displayed as "???".
