Quality is always GOOD when using browseConfiguration

Ignition
#1

We are on version 7.9.12 and I’m trying to get tag quality when using system.tag.browseConfiguration(). I can get the tag value and any of the other TagConfigProps that I’ve tried (except Timestamp), but Quality always returns DataQuality.GOOD even for disabled tags.

Am I misunderstanding what the Quality property is supposed to be or is this property broken?

Also TagConfigProps.Timestamp always returns none.

from com.inductiveautomation.ignition.common.sqltags.model.types import DataQuality
from com.inductiveautomation.ignition.common.tags.config import TagConfigProps
dev = "[default]DEVICES/some_udt_instance"

tags = system.tag.browseConfiguration(dev, False)
for tag in tags:
	print tag.name, tag.getOrDefault(TagConfigProps.Quality)
#2

You can use

tags = system.tag.browseConfiguration(dev, False)
for tag in tags:
	print tag.name, system.tag.read(tag.getFullPath()+'.Quality').value

Thanks MMaynard. That’s more or less the workaround I have been using.

The problem is I’m writing a script that gets info from every tag in a very large system and doing a tag read on every tag greatly increases the execution time of the script.

You can switch it over to a readAll to speed it up

vals = [x.value for x in system.tag.readAll([tag.getFullPath()+'.Quality' for tag in tags])]
print vals
