I'm looking for some clarity on what 0 means in the 'dataintegrity' column. The history tables reference (Ignition Database Table Reference - Ignition User Manual 8.1 - Ignition Documentation) points me towards the data quality codes (Quality Codes and Overlays - Ignition User Manual 8.1 - Ignition Documentation) and the value '0' in that list is Good_Unspecified. Despite being 'good', Ignition seems to be treating the data like it is bad. For example, we have a tag that was alternating between quality 192 and 0, and the Power Chart was breaking the trend when the quality went to 0 (the bottom line corresponds with the table).
I'm just looking for some clarity as the why code 0 is considered bad and what might cause it. I have seen suggestions that it could be related to overloaded communications.
This is with Ignition 8.1.23
