BACnet Point Addressing
BACnet point addressing is very simple for standard BACnet I/O points. Extended addressing is also
available to access non-I/O or proprietary points.
Address Format
A valid address must have at least a point type and a point number:
AV3 — Analog Value #3
BO14 — Binary Output #14
MSI205 — Multi-State Input #205
The list of supported point types includes:
AI — Analog Input
AO — Analog Output
AV — Analog Value
AVG — Averaging Object
BI — Binary Input
BO — Binary Output
BV — Binary Value
CAL — Calendar Object
CMD — Command Object
DEV — Device Object
EE — Event Enrolment Object
FL — File Object
GRP — Group Object
LP — Loop Object
MSI — Multi-State Input
MSO — Multi-State Output
MSV — Multi-State Value
NC — Notification Class Object
PRG — Program Object
SCH — Schedule Object
TL — Trend Log Object
Please note that even though properties of non-I/O objects can be read and written, there is currently no
support for editing an object as a whole object. For example, a single property of a schedule object may
be changed, but editing the dates and times of a schedule in a grid is not supported.
Other Standard and Proprietary Objects
For standard object types not listed above or for proprietary points, the address may be specified as
objectType:InstanceID.
Example:
22032:89 — Proprietary object type #22032, instance #89.
Property ID
If not specified, property #85 (present value) is assumed. A different property ID may be specified with a
comma, followed by the property ID:
Examples:
AV32,81 — Analog Value 32, property ID 81 (Out of Service flag)
22032:89,72 — Proprietary object type #22032, instance #89, property 112 (status flags)
