Issue
Can a UNC be setup as a BACnet server to expose its native Niagara objects as BACnet objects?
Product Line
TAC IA Series
Environment
- Niagara R2
- UNC-520
Cause
By default, the UNC can only act as a BACnet client, not as a BACnet Server. A UNC-520 can be configured as a BACnet Server.
Resolution
Steps for configuring exposing native Niagara objects and BACnet objects:
- Open the properties of the native Niagara object you want to expose as a BACnet object.
- Click on its Config tab
- The foreignAddress must be changed from its default of “-1” to an integer from 0 - 4194302. (BACnet instance number rules applies)
- Apply the change
The object is now exposed as a BACnet object.
The following standard Niagara objects can be exposed and BACnet objects:
- AnalogInput (AI)
- AnalogOutput (AO)
- BinaryInput (BI)
- BinaryOutput (BO)
- MultistateInput (MSI)
- MultistateOutput (MSO)
- Calendar
- Schedule
