I have an OPC connection to a PLC using the ControlLogix legacy driver.
When I add new tags to the PLC online they're not showing up in my tag browser. I've verified that the new tags have the correct scope (global) and have read/write access.
Is there a way to "refresh" the tags on the device? I've tried the refresh browse button in the device configuration but no change.
Ok, so I refreshed the browse again, and I can see the tag in the browser on the gateway webpage but the tag itself still fails to connect.
I also tried restarting the tag in the designer and it still says configuration error.
I'm getting an invalid attribute error.
This is a tag in a UDT. There are other instances of the UDT where this tag is connected with no issues.
I've also just noticed that the OPC tag that is working shows up with a tag icon in the browser while the one that is not working shows up with a folder icon. These are both single float tags in the PLC.
