Now I have installed TIA Portal V19, but I can’t get data from the OPC UA server anymore. I tested the signals using OPC UA test programs, and they are reaching the server I am using. In the TIA Portal software the connection is also established, but when I start WinCC RT, the incoming signals are not being displayed.

Have look at this examples, there are a few combinations available. At least the client side should be explanied for your case: https://support.industry.siemens.com/cs/ww/en/view/63481236 If you have a Unified System then it could work slighliy different. But then we would need a few more information Bye Murof
