NO WAY to read Siemens TP900 OpcUA server

JF_12910141 — Mon, 10 Nov 2025 11:43:22 GMT

I have attempted to connect to the Siemens TP900 OPCUA server with kepserverEx and am unable to do so, but I have no issues with the Unified Automation UaExpert application:

With keptserverEx, I follow these steps but am unable to succeed.

As it was not functioning in the certificates, I used the one I had imported Unified for OPCUASERVER, but nothing happened. I restarted the runtime and the server, but it still does not work.

Hello,

An application protocol such as OPC UA provides specific services and relies on TCP to ensure reliable delivery. Therefore, I recommend checking TCP socket connectivity from the client PC first, using link as a prerequisite for validating the network connection.

After that, please verify the client-side configuration using link.
