I'm struggling to connect an OPCUA interface with a tag on a local kepware instance. The security from the local sever port has been removed.
Please see the attached image for the OPCUA interface configuration and the error message i get.
If i completely clear the "OCPUAInterface - Items" table and tick the "active" checkbox and apply then i do not get an error and the OCPUA state icon turns green, but with the items inplace i get an error message saying "the item ID refers to a node that does not exist in the server address space"
I have no trouble connecting to the same tag on the server ("Channel1.Device1.Tag10") to a standard OPC interface (non-UA), so I'm wondering if I need to reference the tag differently in the OPCUA object...
Any suggestions would be much appreciated. Cheers
Solved! Go to Solution.
Referencing may be a little bit different in UA. You can use a free testclient (e.g. UA Expert) to see how to address correctly. Also, did you try the Import Items.. button? This should automatically import all tags addressed correctly.
Hope this helps.
I used the UAexpert and it told me the correct namespace value = 2 (was previousky using 3)
So seems to be working for now.
