Description
DS-COV-A
The PN/BACnet LINK works as a Client and is able to register with other objects
for notification when a value changes. The service "SubscribeCOV" is used for
this.
DS-COV-B
The PN/BACnet LINK works as a Server and responds to "SubscribeCOV"
packages which are received from other BACnet devices in the PN/BACnet
LINK. Notification of these devices if a value changes is performed via the ser-
vice "ConfirmedCOVNotification" or "UnconfirmedCOVNotification". The service
used depends on the parameters contained in the received "SubscribeCOV"
package.
Note: The server functionality of the PN/BACnet LINK does not support an infi-
nite lifetime for a COV subscription.
