BACnet.Protocol.Services.UnconfirmedCovNotification (bacstack v0.0.1)

View Source

This module represents the BACnet Unconfirmed COV Notification service (Change Of Value).

The Unconfirmed COV Notification service is used to notify a subscriber of a changed value or changed values.

Service Description (ASHRAE 135):

The UnconfirmedCOVNotification Service is used to notify subscribers about changes that may have occurred to the properties of a particular object, or to distribute object properties of wide interest (such as outside air conditions) to many devices simultaneously without a subscription. Subscriptions for COV notifications are made using the SubscribeCOV service. For unsubscribed notifications, the algorithm for determining when to issue this service is a local matter and may be based on a change of value, periodic updating, or some other criteria.
