Note: On the Configure screen, click the [...] button to select the input reference object from the Select Item dialog box. Then select the desired attribute to reference from the drop-down menu.

The Data Broadcast object provides a means of sharing globally useful data with third-party BACnet devices. The data value from an object/attribute to be shared is referenced by this object. Typically, this data may be the outdoor air temperature, or a value indicating whether a building is occupied. The Data Broadcast then broadcasts an Unconfirmed COV Notification message containing the referenced data value when it changes.

On a site containing only Metasys devices, the Data Broadcast object is not useful, and should not be created.

As the number of these objects on a site increases, the network performance may suffer due to excessive broadcasts. Therefore, use Data Broadcast objects only when necessary.
