Description
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.
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.
The PN/BACnet LINK works as a Client and is able to request the identification
of other BACnet devices via the service "Who-Is". This service is used for scan-
ning a BACnet network.
The PN/BACnet LINK works as a Server and responds to "Who-Is" requests
which are received from other BACnet devices in the PN/BACnet LINK with an
"I-Am" answer.
The PN/BACnet LINK works as a Server and responds to "Who-Has" requests
which are received from other BACnet devices in the PN/BACnet LINK with an
"I-Have" answer.
With configured Client object references to input objects (BI, AI), the PN/BACnet
LINK requires this BIBB to be able to read properties from these objects.
The PN/BACnet LINK works as a Server and responds to "ReadProperty" re-
quests which are received from other BACnet devices in the PN/BACnet LINK.
With configured Client object references to output objects (BO, AO), the
PN/BACnet LINK requires this BIBB to be able to write properties to these ob-
jects.
The PN/BACnet LINK works as a Server and responds to "WriteProperty" re-
quests which are received from other BACnet devices in the PN/BACnet LINK.
The PN/BACnet LINK assumes the representation of the S7 controller in the
BACnet network. The object types listed in the section Server objects (Page 21)
are supported.
