The tables below reflect the extended sub-status and flag description of the quality code which is Industrial Edge specific and encoded in the high-byte of Industrial Edge quality attributes. The intention of Industrial Edge specific extended sub-status is to describe the data quality more distinct than the sub-status according to PROFIBUS-PA. Nevertheless, to support 3rd party collaboration based on standards only, a best-effort sub-status is always set, even if a more distinct extended sub-status is present.
