Alarm management system for PLC, HMI products
Unitronics’ UniStream Alarm Management System has been added to its PLC + HMI products and is designed to allow operators to detect alarms, analyze them, and take the proper corrective actions. Features include the alarm banner, which can immediately alert operators when alarms occur and the alarm summary table that enables managers to review active alarms and to perform any necessary actions. Another feature is the alarm status viewer, which allows operators to view all of the alarms that exist in the system, check their status, disable and shelve them, and enter comments via UniStream’s HMI virtual keyboard. The system supports state-based alarm suppression options, which allow the programmer to optimize alarm reports, prevent ‘nuisance’ alarms from occurring and avoid alarm flooding conditions. An optional advanced configuration section enables programmers to optimize alarm announcements. A binary alarm log file is used for logging all alarms data as well as operator control actions. All of these UniStream features empower automation engineers and machine builders to develop safer and more efficient applications.
