public class SummaryAlarmProcessor extends DefaultAlarmProcessor
This class listens to alarm events from input links (PVs) and converts them to alarm state of this record in following way:
  • Sets record alarm state to highest alarm state of input links.
  • Sets record value to 0 if there is no alarm state and 1 if there is alarm state in input links.
  • Sets record listens to machine state and blocks alarms when machine state does not match mask.

      Specified by:
      configure in interface ValueProcessor
      Overrides:
      configure in class DefaultAlarmProcessor
      Parameters:
      record - the parent record.
