Hey, i've tried to add some of our OT Systems. In this case i tried to add a BECKHOFF OPC UA value.

One of the needed NodeIDs is: ns=4;s=GLT.GLT_EF_IN.rGLT_Real_03 But now i get an error "The provided NodeID (s=GLT.GLT_EF_IN.rGLT_Real_03) is unknown to the server"

If i set the NodeID to one in the highest locations in the folders it works as aspectet. ( ns=4;i=1301 )

I think the issue is with the folders.

Can you give me a hint what to change that i can read the needed values?

There seems to be an error with the variables for the node id. It does seem like the issue is mostly on the Beckoff side and from the PRTG perspective we might not be able to get much more information, but you can enable the 'store result' option in the sensor settings to generate a sensor debug file to get more information. Then we'd recommend to open a support ticket with the sensor screenshots and debug file.
