No other screens can be selected." Everything works fine except this. Communication, fast counter etc. works fine. What could be the problem? Thanks.

After that download project again. Is it solved? What version of TIA Portal are you using? (Incl. Service packs and updates) Best regards, Wizard

I get a warning when i rebuild all: "The configured interface operating mode combined with the 'DP' profile setting on PROFIBUS 'PROFIBUS_1' may affect the communication via the S7 connections.,,, and i downgraded the panel before the first load. Does might cause a problem?

Here you can download latest update for WinCC V13 SP1: Updates for STEP 7 V13 SP1 and WinCC V13 SP1 I found the following link: (unfortunately it is about WinCC flexible) How do you configure a connection between WinCC flexible Runtime (PC/Panel) and a SIMATIC S7-300/S7400 via PROFIBUS/MPI? Best regards, Wizard
