Hi yyscom.

That is not what LD asked about.
If you are in doubt, then post a screenshot from STEP7 Hardware Configuration. Be sure to display the station where the i/o adresses I0.0..I3.7 or IW0..IW2 is used.

Another thing you can investigate, is what is the status of all LEDs on the CPU, CP modules, and IM modules. And check both main rack as well as subracks and DP slave stations.
