3rd party opc ua tags will show up in the browse devices dialogue which you can open from the designer under the tag browser, +, browse devices. You can then drag tags from that dialogue into your ignition tag browser to use in your project
OK, I've started over and I'm just trying to make a "Device Connection", I'm using the Micro820 Driver. It shows that it is connected - The connection name = Polymer. This is all on my bench on a local connection, laptop is 192.168.1.118, Plc = 192.168.1.101 (port=44818), I have my firewall turned off.
Now I try to setup a realtime tag provider I select Remote Tag Provide (Gateway Network) Here I name the "Tag Provider = PolymerTags, Gateway= 192.168.1.101 (Address of Plc) Provider= ???? I have tried several different things I am assuming the Provider is the connection which is Polymer. But I don't know.
Now when I go to designer and try to Browse my tags I can select fro the dropdown list "PolymerTags" which is my tag provider , but none of my tags show up?
You drag and drop from the OPC Browser to the Tag Browser. Or manually create an OPC Tag and set its OPC Item Path to the path copied from the OPC Browser.
In that dropdown box you would normally have a tag provider called "default". If you haven't deleted it already, select it. Then click that "+" button over to the left to start browsing/adding tags.
If you have deleted it, you'll have to go back into the gateway and add a new standard tag provider.
I already linked you to documentation that explains this browse/drag/drop process via that "+" button: Tag Browser | Ignition User Manual
You can also open the OPC Browser directly from the View menu.
It seems like you would benefit a lot from taking some of the free Inductive University training.
