Event Enrollment Objects / Algorithmic Change Reporting

Event Enrollment Objects
The primary purpose for Event Enrollment objects is to define an event and to
provide a connection between the occurrence of an event and the transmission of a
notification message to one or more recipients.
The Event Enrollment object contains the event-type description, the parameters
needed to determine if the event has occurred (Algorithmic Change Reporting), and
a device to be notified. Alternatively, a Notification Class object may serve to identify
the recipients of event notifications. A device is considered to be "enrolled for event
notification" if it is the recipient to be notified or one of the recipients in a Notification
Class object referenced by the Event Enrollment object. Event Enrollment objects
are the basics for algorithmic change reporting.
Algorithmic Change Reporting
Algorithmic change reporting enables a BACnet device to provide one or more alarm
or event sources, defined by Event Enrollment objects, to generate alarm or event
notifications that may be directed to one or more recipients. Any of the
standardized algorithms may be used to establish criteria for change reporting.
Once established, occurrences of change may be reported to one or more recipients
based on further criteria. Changes of value of specific properties of an object may be
programmed to trigger event notifications to be sent to one or more recipients based
on a notification class. Typically, event notifications are sent to application programs
represented by processes within a notification-client device. The object(s) whose
properties are referred to is known as the Reference Object(s). The criteria used to
ascertain that an event has occurred are determined by the Event Type, for
example, CHANGE OF BITSTRING, CHANGE OF STATE etc.
