Issue
An I/A Series R2 station fails to send BACnet alarms to a third-party system. The error log shows:
tridiumx.bacnet.BACnetException: E_BACNET_UNRESOLVED_DEVICE_ADDRESS.Product Line
TAC IA SeriesEnvironment
- I/A Series R2
- BACnet
Cause
The station does not contain a BACnet device object for the target device. Without this object, the system cannot resolve the device address required for alarm routing.
Resolution
- Ensure the station includes the BACnet device object for the target device. This object provides essential details such as IP address and device instance.
- Verify the target device is online and capable of receiving BACnet alarms.
- Use BACnetUtility and the learnNetwork command to create BACnet device objects for all target devices.
- Refer to the I/A Series R2 BACnet Integration Reference Guide (section: Configuring for BACnet Alarm Generation) for detailed steps.
Additional Notes:
- Only Niagara objects exposed as BACnet objects (AIs, AOs, BIs, BOs, MSIs, MSOs) can generate BACnet alarms.
- Alarms are not regenerated if the BACnet device is offline during transmission.
- Enterprise Server cannot generate alarms for subordinate stations; each station must be configured individually.
