Data Quality bit mask

is there a Data Quality bit mask explanation?
i can find in the help the list of the possible states, but not the mapping with the tag value…
tnx

Data quality is not a bit mask. Here are the possible values and their corresponding overlay:

my tags have often quality set to -1 or 192.
i can’t understand what this means…

192 means GOOD quality.

I’m pretty sure -1 was an alias to a generic bad quality state iirc.

I’m looking around to see if we have a better list of DataQuality<–>Value than the overlay section Travis mentioned, but it’s not looking good…

Looks like we’ll have to add one.

i’m waiting. thanks :thumb_left:
