Data Quality Check in OSI PI & GE Proficy Historian

While retrieving data from OSI PI Historian or GE Proficy Historian, is there is any option of selecting the Output Flag as 1/0 in order to have a check on data quality or health.


For e.g., if turbine MWs are being retrieved from DCS and at that moment they are bad MW does PI or GE Proficy determine if the data health is not good and gives any indication or raises any flag.

If so, what's the logic behind this data quality tool/logic running in there.


I just wanted to understand more about the data quality checks which are available in either of these Historians (OSI PI or Proficy) to evaluate the health of data coming from MkVI/DCS.

How does these historians determine if the data quality is good or bad?
