it should be done through Siemens OPC Server? or exist other way?
Welcome to PI Square.
I'd like to say that WinCC 7.2 should offer various protocols to be connected to systems like PI.
May I suggest PI Connector for Siemens Simatic PCS 7 or PI Connector for OPC UA?
I believe that some other protocols can also be used to send data to PI.
You should make sure that OPC connectivity pack is installed on WinCC. In newer versions it could include OPC UA!
We use OPC DA and Matrikon OPC tunneler!
If you wish to use the PI Connector for Siemens Simatic PCS 7, you must have the Siemens OPC UA (Unified Architecture) server for OpenPCS 7 installed.
