Hi

I have a S7-1500 plc thats running as a client to a OPC UA server, and when ive gone online against the server to add the nodes that i need to handle i get a warning of "The node ID does not exist in the OPC UA server interface" when i do consistency check. I used UaExpert to go online against the server and there i can find the nodes and see the data in them. ´Does anyone have any experience with similiar issues? I cant find a way to modify the node adresses in the client window in TIA.

Best regards

Hello Hann3s

Do you have tried to go online from our TIA Portal -> PLC-> OPC UA communication-> Client interfaces-> your client interface -> Online Access (on the left side)

Basically the same as you would go online with UA Expert.

Then you can see the OPC UA Server interface and can drag and drop the items you need to your client interface. If your OPC UA Server does also support the export of a XML file for the interface you can also import these information.

(some general information:)

Hi

Yes this is the way i added my nodes to my client interface in TIA, wich is why im so confused about the wrong node adress error

Hello Hann3s

does it only appear with the array tags in your screenshot or also with common datatypes like an integer (without arrays)?
