I had previously been using version 8.1.x of the Gateway/Designer, imported a client’s project, and after creating my Device Connection, was able to both browse the tags from the CompactLogix v37 as well as get good data. Unfortunately, I quickly realized that they used some custom Images, and after learning those are put into the Gateway database, I understood that I needed to do a Gateway Restore.
Their Gateway was done in something higher than 8.1, so I downloaded/installed 8.3.2. While it had the project already in it, it told me I didn’t have permission to open it, so I re-imported it over top of it.
Recreated my Device Connection to the CompactLogix, opened the project in Designer, could browse all of the tags in the OPC Browser, added them to my Tag Browser, just like I had originally done in 8.1, however, every tag now has Error_Configuration:
Both Device Connection and OPC UA Server Connection say Connected in with the green check, so I am at a loss what was different between when I was doing this in 8.1 vs 8.3.2?
Hover over the "Error_Configuration" or open a tag and go the diagnostics panel, you should be able to get a little more info about the configuration error.
Just to confirm to myself, I went back and did a full uninstall/reinstall of 8.1.45 to confirm that I was reading data. The only thing I added was the Device Connection. Everything else, such as the ‘Default’ Tag Group was baseline install. Could read tags just fine.
Did a full uninstall/reinstall of 8.3.2, imported project. Same thing, only added Device Connection, everything else default. Could read tags.
Then did the Gateway Restore. Had to remake my Device Connection. Now it looks like they have changed the Tag Group to something else, and yes, when I hover over the Error_Configuration, I see:
That to me implies it’s still looking for the “Default” tag group, when they created one called NBU_Main? (default doesn’t exist)
Yes, sounds about right. You didn't import the tags, you drag and dropped them in yourself, so they tried to use "Default" as the tag group.
Select all the tags, edit them, change the tag group to the one that exists.
I’m still pretty new to Ignition.
I used the OPC Browser for this:
Is this not the normal way, or just not if the Tag Group is not Default?
When you mention importing the tags, does that mean doing a tag database dump from the PLC to a .CSV and then import?
This is the normal way, but it always puts them into a tag group called "Default" by default.
You restored a backup from somebody who deleted this group and created other groups. You just have an extra step to deal with now, where you need to configure any tags you create to be in the intended group.

That does seem like what they did, and I have no idea why.
They did add a couple tags under the custom ‘NBU_Main’ Tag Group they created, but as I have thousands of tags to pull in, I just recreated the deleted ‘default’ group and now I can read them just fine.
Appreciate the assistance!
