Rate Reasonability

This application compares an incoming flow rate from a rate point against a configured reasonability limit to assist Controllers in identifying a questionable flow rate.

If a flow rate exceeds the reasonability limit, AVEVA Enterprise SCADA:

• Generates an alarm and logs an event.

• Continues to use the last good flow rate to process software accumulator functionality.

  Note: Rate Reasonability alarms are not part of Alternate Alarm Limits configuration.
