Definicja event area

A filter criterion that limits the scope of events to be reported from an OPC Alarms/Events server.

The event area comprises the namespace within which events may occur and that can be set up on the OPC Alarms/Events server.

The nodes of the event areas represent the areas in which events may occur (such as a room). The leaves represent the sources from which the event information comes (such as a door). Several events can be defined at one source (such as monitoring the temperature value and the temperature sensor).
