I’m working with add on instructions that have local tags I need for display on an Ignition screen.

For a particular add on instruction, I’ve got a local tag that OPC-UA server can read with good quality. But another local tag is shown in the OPC-UA quick client but has a bad quality. Additionally, an instance of an alarm AOI within another AOI shows all bad quality for the tags. The path is seen below. where “test\_fault” is a local AOI tag instance within Conveyor\_PF527 which is another AOI.

[Ignition OPC-UA Server]ns=1;s=[line\_control\_L83E]Conveyor\_PF527.testFault.cfgAlmDescription

Is there a limitation in the OPC-UA server with pointing to local tags within AOIs as well as nested AOIs and local tags?

In Logix Studio, the “External Access” column is hidden by default when looking at AOIs. If you right-click and show it, do the local tags you want have their external access set to something other than “None”?

I’m embarrassed I missed that, but thank you Kevin for the fix.
