/** @defgroup ALMEVNT Alarm and Event Management BIBBs
|
|
* These BIBBs prescribe the BACnet capabilities required to interoperably
|
|
* perform the alarm and event management functions enumerated in 22.2.1.2
|
|
* for the BACnet devices defined therein.
|
|
*//** @defgroup EVNOTFCN Alarm and Event-Notification (AE-N)
|
|
* @ingroup ALMEVNT
|
|
* 13.6 ConfirmedCOVNotification Service <br>
|
|
* The ConfirmedCOVNotification service is used to notify subscribers about
|
|
* changes that may have occurred to the properties of a particular object.
|
|
* Subscriptions for COV notifications are made using the SubscribeCOV service
|
|
* or the SubscribeCOVProperty service.
|
|
*
|
|
* 13.7 UnconfirmedCOVNotification Service <br>
|
|
* 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.
|
|
*//** @defgroup ALMACK Alarm and Event-ACK (AE-ACK)
|
|
* @ingroup ALMEVNT
|
|
* 13.5 AcknowledgeAlarm Service <br>
|
|
* In some systems a device may need to know that an operator has seen the alarm
|
|
* notification. The AcknowledgeAlarm service is used by a notification-client
|
|
* to acknowledge that a human operator has seen and responded to an event
|
|
* notification with 'AckRequired' = TRUE. Ensuring that the acknowledgment
|
|
* actually comes from a person with appropriate authority is a local matter.
|
|
* This service may be used in conjunction with either the
|
|
* ConfirmedEventNotification service or the UnconfirmedEventNotification service.
