I am learning S7 & WinCC. I have two question regarding WinCC & S7.
1) WinCC how communicate with S7. In our plant S7-414H PLC and WinCC HMI have been used. If in WinCC no data is coming from S7 then which network diagram i need to check in S7? What is the interval of S7 sending data to WinCC ?
2) WinCC & OPC how they communicate each other?
