Posted: Tue Sep 02, 2025 8:25 am
Hi everyone,
I am working on WinCC OA for OPC UA connectivity , I need your guidance/help to execute my WinCC OA application.
Application ā connectivity between Siemens S7-1200 PLC/Prosys OPC UA Simulation Software (OPC UA Server) to WinCC OA (OPC UA Client).
WinCC OA Version - V 3.20.
Status ā I am able to established OPC UA Server connectivity with WinCC OA OPC UA Client. I have also created the database, and it is showing into Para (attached screenshot)
I want your support for below points ā
How to Read/Write data of Siemens S7-1200 PLC/Prosys OPC UA Simulation Software in WinCC OA.
I want to write a control logic e.g., if a value exceeds a trigger an alarm or set another tag).
In case if you have step wise documentation, could you please share with me so that I will go through it as well
Thanks in advance.
