Customize the IS_ZERO_GOOD_QUALITY key value

Note: For information on overriding default configuration settings, see Modify configuration settings.

This key allows you to determine whether the returned quality of zero will be good or bad. In this instance, if TRUE is entered, a quality bit value of 0 would indicate a good quality analog or rate point value, and a quality bit value of 1 would indicate a bad quality analog or rate point value. If FALSE is entered, 0 would indicate a bad quality analog or rate point value, and 1 would indicate a good quality analog or rate point value. For more information on data quality, refer to volume 1 of the AVEVA Enterprise SCADA RealTime Administrator documentation.
