We have an Engineerinf Station with Simatic Manager and WinCC 7.5 SP1 Update 5.

I can connect to my PLC(s) and download to the PLS(s) via the profinet connettion.

I can open the WinCC Project and go online with WinCC and operate the machine(s).

But Simatic Shell on my Engineering Station is not showing the WinCC server on the machine to be connected and I can also not download WinCC modifications to the server.

What could be wrong with the settings in my Engineering Station and how do I correct t so I can download to th WinCC server(s)?

Hi,

This FAQ usually does the trick:

With special attention to the name resolution using the "lmhosts" file.
