Creating a New BACnet Object

BACnet utilizes "objects" to represent either physical items or descriptions of processes/calculations/operations. There are multiple object "types", each with a list of required and optional properties. These include:

Value	Object Type	Value	Object Type
0	analog-input	12	loop
1	analog-output	13	multi-state-input
2	analog-value	14	multi-state-output
3	binary-input	15	notification-class
4	binary-output	16	program
5	binary-value	17	schedule
6	calendar	18	averaging
7	command	19	multi-state-value
8	device	20	trend-log
9	event-enrollment	21	life-safety-point
10	file	22	life-safety-zone
11	group

To Create a New BACnet Object:

Right-click on a device in the Workbench64 Project Explorer then click on "Object".

The BACnet Object properties window will appear in the right pane of Workbench64. Enter a Name and Description in the top text entry fields.

BACnet Object Properties

The following Object Settings may be changed:

- Object Type – Choose from AnalogInput, Analog Output, AnalogValue, BinaryInput, BinaryOutput, BinaryValue, Calendar, Command, Device, EventEnrolment, File, Group, Loop, MultistateInput, MultistateOutput, MultistateValue, Program, Schedule, Averaging, TrendLog, LifeSafetyPoint, LifeSafetyZone, TypeAccumulator, PulseConverter
- 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.
