Description of the Automatic Alarm Verification System

A human machine interface (HMI) for a distributed control system (DCS) typically has an alarm system to provide and store information pertaining to alerts from various machines in a production facility or other industrial setting. One aspect of using such alarm systems is the need to verify alarm performance. Alarm checkouts, for example, are generally needed for almost every machine project conversion (e.g., modifying a machine for the production of a different product or grade).

Traditionally, alarms are checked manually. That is, a lookup table is referenced with variable/tag/bit names, the names are manually typed in and the alarm display device is checked to verify that the appropriate alarm is on. Often times, more than one individual is occupied by this activity for a 12-hour shift or more while this procedure is being performed.

To decrease the labor required to check out an alarm system, an automated alarm checkout procedure has been developed. This automated system includes an executable application and can be used, for example, with a quality control system that tracks process events and manufacturing events that may aff...
