Good day.

I stuck with WinCC and some PLCs. From WinCC PC I easily ping PLCs and their respected HMI Panels, also I able to go to panels via Sm@rtClient. In Simulation mode on other PC system WinCC and PLCs connect without any problems, so it isn't bad IP issue.

Any solution?

Thanks.

have you check the correct communication settings on the pc winth wincc pro rt?

 I'm terrible sorry, but I can't find any place in WinCC RT (outside TIA Portal)  there I can find IP settings. In TIA portal it's correct (double check).

maybe some screens of your configuration would be nice.

 Here it is:

what is configured under access points?

 Thanks a lot! I actually right after posting a massage start to look at the different options and change access point to right option (although I make several takes) it start to work just fine.
