Hello guys,
I would like ask you for an advice. I have been strugling with OPCUA communication and I really dont know what else I should do...
Do you know why I cannot create the endpoint configuration ?
TMC file - checked
UA Endpoints security - NONE
It seems like there is no server running...I would appreciate any kind of help ... this is my first project with Twincat OPC UA
Thank you
Add the TF6100 License in the project.
Restart your OPC UA Server.
Activate the configuration and log in the PLC.
Enable the OPC UA Configurator tool.
Click Connect, Add Server, you should see the endpoints at the dropdown menu.
Also, make sure that you are not running multiple OPC UA Servers. It also causes some conflicts.
@beckhoffsupport This is exactly what I did but there is still no endpoint.
It seems that only one OPC UA server is running.
I've really reached a dead end. I have no idea where is the problem ...
@svatoslav-tosner Are you running also any other OPC UA Client/Server program which might be using the 4840 port? I was able to create this exact issue by mistake 😀 I removed the other client/server programs, restarted the PC, everything was good again. Other OPC UA programs were causing the conflict.
@twincontrols Thank you for your help, but it seems that only this app is running on the port 4840.
Edit:
I played a little bit with TwinCAT OPC UA configurator and came across this message:
Could this be causing the problem ?
Hi, if you try to follow this tutorial guideline, I think you might find your problems answer.
If you don`t, tell.

@sambba Thank you for your reply. I followed all these steps but still not able to find any endpoint.
I also tried this video but with the same result:

I have the exact same issue like yours. Did you manage to solve it.
Hi,
problem was that the port of OPC was already used by different software. Try to change the port.
I am sorry for this simple answer but I'm on vacation this week and I don't have my laptop with me.
