OPC UA Server unable to start manger

[Rtonev]

Hello,

I was following a WBT (recorded) and we had to add a OPC UA Server manager, upon starting the manager i get a severe error in the Log Viewer, but I can't find any solutions to my problem.

Code: Select all

WCCOAopcuasrv(1), 2024.07.31 16:31:46.316, PARAM,SEVERE,     11/opcuasrv, OpcUaSComm in Function boot, Can not initialize or start up the OPCUA UaModule (Statuscode: OpcUa_Bad)

Does anyone have any suggestions ?

TIA!

Could be related to the WinCC OA version and OS you are using.
Do you use RHEL9 and a low WinCC OA 3.19 patch?

The part of the log messages only shown log entries for the OPC UA Server.
To get the full picture please check the log entries for the Event Manager. Possibly the Event Manager rejects the connection for the OPC UA Server.
