About alarms

You can create AVEVA OMI applications that generate alarms and events to provide the status of a running business process.

• Alarms warn about process conditions that can potentially cause problems. Typically, you set up an alarm to become active when a process value exceeds a defined limit. For example, you can set an alarm for a pump that warns when no fluid pressure is detected.

  An alarm is an abnormal condition that requires immediate attention. An operator usually acknowledges an alarm. Application Server objects handles the real-time reporting of alarms and provides special clients for viewing them.

• Events represent normal system, application, or user occurrences that produce status messages. A typical event occurs when an operator logs on to an application at the beginning of a work shift. Application Server can detect events, store them as historical data, and report them to client applications.

Application Server objects include built-in event and alarming reporting capabilities. You must configure alarms for each object in the IDE to use the event and alarm functions.
