Using 8.1.47, PLC is a Siemens S7-1518. The customer is handling the PLC and was advised by IA tech support that people often setup the OPC-UA on the PLC and then the tags become browsable to Ignition.

That works and the tags read correctly.

But I took a look at the tag and I saw this as the OPC Item Path

`nsu=`[`http://www.siemens.com/simatic-s7-opcua;s="Stall01"."StartDateTime"`](http://www.siemens.com/simatic-s7-opcua;s=%22Stall01%22.%22StartDateTime%22 "http://www.siemens.com/simatic-s7-opcua;s=%22stall01%22.%22startdatetime%22")

Never seena url in OPC Item Path before. I tried it a few more times with other tags and same story. Is this expected/normal/acceptable or something worth troubleshooting? Perhaps they configured something poorly ont he PLC OPC side?

It’s normal. It’s a namespace URI, and any node from any server belonging to a namespace at index 2+ will come in fully qualified like that when drag and dropped.
