Events do normally not need immediate operator attention. Alarms They are messages that alert you to an abnormal process or system state. Alarms generally need operator attention and action. Process alarms e.g. pressure too high in a reactor, level too high in a tank, etc. Object alarms e.g. motor temperature too high, etc. Alarms need to be acknowledged.
