I want to find out using a script, how many tags are being used in the tag browser for each device. Only the tags that I have pulled in from the OPC browser. Not sure of the parameter.
Use the tag report tool, Tag Report Tool - Ignition User Manual 8.1 - Ignition Documentation
Otherwise, if you're not up to a version with that in it, you'll need to use system.tag.browse to get all tags, then create a list of those full paths + ".opcitempath", read those, and then extract the device name from the values
