I am currently using a 3rd party OPC server for FPMI. (Top Server) Is there a way to import the tags I am using from Top Server to the internal OPC-UA server in Ignition?
There’s no magic solution here. You’ll need to export them in whatever format that server can export and then massage that into the SQLTags import format.
You’ll also need to configure each of the devices you might need in the Ignition gateway. The name of these devices will be an important part of the SQLTags import format for each tag.
