OPC Items with null reference
I have Kepware opc server connected to ABB 800xa v5.1. My communication is working fine but there is an issue coming Kepware event log (snapshot attached). The error I am receiving in kepware is "Attempt to add item'' failed." which means that the client i.e., ABB OPC client is trying to add items with null item id? But I am unable to find these at the moment. But even if I find them how can I delete them. Since I am unable to delete any tags in control connection?

Have you performed upload, or did you create the objects/item IDs manually?
I have not (yet) seen the uploader creating a null item from a non-null item ID returned during upload.
The item ID should be visible in the OPCAdapter Basic log of the AdvDsOPCConnector component in afwapplogviewer.exe tool. Sorry, no manual for this tool - I teach some of the techniques in the E143 Troubleshooting System 800xA expert workshop.
