Hi there ! I´m working with PCS7 v6.1 SP1 (WinCC 6.0 SP3a) and testing the OPC communication (WinCC working as OPC Client). We´re able to add the the variables to WinCC but we cannot communicate with this variables afterwards.
In order to enter the variables, we add the OPC driver and select from the list (system parameters)the station where the OPC Server is placed. The problem is that once the variables are created, we´re not able to make them communicate and update the values and monitor these values in the screens. I´ve noticed that the path to the server variables is quite long and has strange symbols and whenever we try to update the variables manually, the path is divided in two segments.
And if we check the Status of the Connections, the value is updated just once (just the first time with the Picture Change).
