HMI Alarm Manager Counters

HMI Alarm Manager counters provide you with the capability to review a detailed performance of the alarms in one or all projects running on your system. Any one counter may raise a red flag that the system is generating more alarms than anticipated. When all of the counters are reviewed, the possibility that there is a problem in the system can be evaluated.
