Product Overview The VWG-50 and related wireless controllers are targeted to retrofit applications where the addition of communicating field bus wiring within the building space is prohibitive. The Gateway and Communicating Controllers with wireless field bus encourages the use of existing wiring utilized by existing electronic controller type controls.

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.

Objects Supported By Model Room Temperature, Outdoor Temperature and Room Humidity need to have their Boolean override counterpart object set to “Override” first if the present value needs to be written over from the network. Ex To set a network present value on the numeric “{Room Temperature” numeric object, the “Room Temperature Override” Boolean object needs to be set from Normal to Override.

Tips and Things You Need To Know  After the initial configuration of your device and if your BAS allows you to remove objects, we suggest that you remove all objects not used by your application. This will prevent unnecessary polling of non-used objects and to help speed up the network. This is mandatory on MS-TP integrations. A fully loaded VWG can contain upwards of 800 objects for 30 controllers.  Be sure all controllers connected to a VWG are using the same PAN ID and Channel as the VWG.
PAGE 30
 Always try to minimize BACnet messages to the VWG to the minimum. Care must be taken to insure that the rate on incoming read or writes BACnet messages does not exceed the throughput of the wireless ZigBee network. On an MS-TP VWG, please also remember that you are limited by the maximum throughput of MS-TP at the selected and used Baud Rate. Updating 800 objects at the front-end system over MS-TP will take a certain amount of time if you use lower Baud Rates like 9600 or 19200 KBps.
