Hi to everyone, I have a PLC S7-1200 and 2 differents and independient Servers with WinCC Explorer V7.5.

In one of the servers, the connection works fine trough SIMATIC S7-1200, S7-1500 Channel (OMS+), I can read and Write data to my PLC S7-1200, but with the another Server I can not connect my PLC, is not recognized (see the attached document).

What should I do? I can ping from my Server to my PLC and is OK.

I appreciate any suggestion, thanks in advanced  

Hi everyone, I can solve my problem with this procedure, using the tool SIMATIC SCADA Export for TIA Portal .

Please follow this link:

Why is SIMATIC WinCC Runtime ≥ V7.5 SP2 Update 4 not establishing a connection to a PLC SIMATIC S7-1500 ≥ V2.9 / S7-1200 ≥ V4.5 / Software Controller ≥ V21.9?
