[?]: Communication between WINCC and CPU226 via ethernet

[Adamski]

I'm trying to connect to a CPU226 with CP via etehrnet .I'm Using PC ACCESS as the OPC Server .
I get the connection with PC ACCESS and I'm able to read he tags/symbols with a good connection.
The problem is as soon as I start up wincc ,I lose the connection .
In WinCC I'm connection to one other CPU 300 series via ethernet .
This CPU is on a seperate ethernet card in my SCADA station.
I'm tryin to connect to the 224 via company network .
After losing the connection ,I can't get the connection again unless I restart the PC .
Could Someone please give some advice .
