PLCnext OPC UA ( SIM)

Dweller6554 · February 2023

Trying to connect to OPC Ua on the SIM and I have managed to get UA Expert to connect, but when I try the same connection with Cogent Data Hub I get an error ;

"BadIdentityTokenInvalid: The user identity token is not valid. Possible cause, the user token policy is not supported on the server."

I have the Authentication sent to User Name and am using admin and plcnext I have the endpoint URL set to opc.tcp://localhost:4840

Does it make a difference if you tick the box "Always accept invalid server certificate"? UaExpert prompts for this if the server certificate is not trusted.
Are you able to connect by disabling user authentication in WBM, and then using "Anonymous" authentication from the client?
Are you able to connect to other OPC UA servers, e.g. one of the free ones here?

If you do try other servers, then please note that installing multiple OPC UA servers on one PC - including the one in the PLCnext Engineer simulation - may cause conflicts on port 4840, so you should only have one OPC UA server running at once.

When using the Sim how do you get to the WBM

https :// localhost/WBM

https :// 192.168.1.30/WBM

https :// 10.0.2.15/WBM

All of above end up in a timeout webpage.

From the Info Center:

https://www.plcnext.help/te/PLCnext_Engineer/PLCnext_Engineer_Simulation_intro.htm

... so the WBM should be accessible on https://localhost:5050
