Viconics VWG-50 (Classic ZigBee) BACnet Integration Manual - Manual (Page 5)

5
Objects supported.
A single VWG can support a maximum of 50 controllers. All different models of controllers available from Viconics
are supported by the VWG in wireless version
The list of points available for each controller is different and has been optimized to best suit typical applications
used by every single typical controller model available.
It is important to mention that versus the wired BACnet MS-TP models, which offer ALL possible objects
supported by the controllers ( user, status and configuration objects ), the wireless versions only support the
points, which are of relevance for typical BAS interaction. As such most configuration properties of the controllers
are not available through BACnet and need to be changed locally at the controller.
The VWG will automatically assign each object instance number based on when it is added to the BACnet VWG
database using the VWG configuration tool. Please refer to document on the VWG set-up / diagnostics ( LIT-
VWG-50-SETUP-Exx ) for more information on creating the VWG BACnet database.
The structure of each BACnet object is automatically created by the VWG and is based on the following structure:
Object Name. The current assigned BACnet object name is chosen by the user and has several options.
Options:
Example of a VZ7200F5X00 WITH COMM ADDRESS OF 15
“Point_Name” _”Device_Name”: Ex: RoomTemp_VZ7200F5X00W_15
“Point_Name” _”Device_Address”: Ex: RoomTemp_15
“Device Address” _”Point_Name”: Ex: 15_RoomTemp
“Device Name” _”Point_Name”: Ex: VZ7200F5X00W_ RoomTemp_15
Object ID ( Instance Number ) Is automatically assigned by the VWG during the BACnet database creation as
each wireless controller is added to the VWG.
