Good morning Team,

I am getting this error on a tag with a connection to Ignition OPC UA Server.

Any idea on where I should look?

Hi,

what opc UA server are you using ?

This is the server telling you it doesn’t recognize the OPC Item Path.

From the syntax it looks like a maybe a Logix device of some kind… so maybe it’s not connected, hasn’t browsed, or that tag simply doesn’t exist in the PLC program.

Thanks Kevin, that it what I thought. I need to verify what it is actually in the PLC.
