Adding a BACnet Object

1. Launch the Workbench.
2. Switch to the BACnet Provider.
3. In the tree, find a device where you want to create an object.
4. Select it and, from the context menu, select the ‘Add Object to Database’ item OR click on the 'Add Object to Database' button in the Edit section of the Home ribbon. The Object properties window will appear, as shown below.

5. In the Object Settings section, choose your desired Object Type via the pulldown menu, as shown above.

Supported BACnet Objects are:

• Access Door

6. Fill in the form that opens.

1. The following properties are common to many of the object types:

• Instance - An Object's Instance number identifies it within a BACnet Device. In combination with the selected Object Type, the number entered here will then determine the Object ID (see below) in the field to the right.

• Object ID – Objects on an interconnected BACnet/IP network should have unique numbers to quickly identify them and prevent possible confusion.

• Override Default Polling Rate (s) – Sets the frequency of communication between BACnet objects and the BACnet Connector. Range can be between 0 and 4194303.

• Override Default Priority – Sets a number between 1 and 16 as to the criticality of an object, in comparison with others. Assigning a priority level marks the importance of messages and which will override others. Some numbers are pre-assigned (1, 2, 5, 6, 8), with life safety naturally having highest priority. Other numbers (3, 4, 7 and 9 through 16) are not assigned and therefore are available for users to set their own priorities. Default is 8.

• Override Service Type – BACnet service type to be used for data reading.

7. Click the ‘Apply’ button to create an object in the device.
