Event
An event is an indication that something has happened in the system. Typical events
are changes of object values, alarms or warnings, or alarm definitions. Events can
cause printouts, automatic control operations, event lists and report database
registrations.
The event list displays events that have occured in the system. It also informs about
activities by other users, operations of objects, acknowledging alarms, editing of
limit values and so on. With LIB 500 you can define own filters with the event list
tool, depending on what kind of information you want in the event list. One or
several criteria may be used to filter out unwanted information from the event list.
