Stack:Unresolved device address

Using offline discover to add Bacnet proxy points into the driver database whilst the BacnetDevice is offline will create a number of BacnetException:Stack:Unresolved device address debug messages in the Application Director view. The status flag type and status flag colours will indicate the condition of the proxy point.

In these examples, offline discover has taken place to add Bacnet proxy points into the driver database. The BacnetDevice is initially offline and then afterwards brought into an online condition. Inspection of the Application Director view shows a number of messages which occur during the discover while the BacnetDevice is offline.

 

NOTE: The behaviour of the Bacnet proxy point status flag type and status flag colours are different between the Niagara AX 3.7.x and 3.8.x releases.

NOTE: The Bacnet proxy points are shown down indicating driver communications to the parent BacnetDevice are currently lost, based upon the device status (Monitor) configuration for that network.

NOTE: When driver communications to the parent BacnetDevice are subsequently established, based upon the device status (Monitor) configuration for that network, the Bacnet proxy points are shown ok

NOTE: The Bacnet proxy points are shown fault which typically indicates a configuration error or a “native fault” in the parent BacnetDevice.

NOTE: When driver communications to the parent BacnetDevice are subsequently established, based upon the device status (Monitor) configuration for that network, the Bacnet proxy points are shown ok. Note also that the Read: Stack:Unresolved device address is updated when the database view is Refreshed.
