After upgrading your IXrouter3 to firmware version 3.29 or higher, your BACnet/IP data source(s) stopped working.

Clicking Run test at the data source variables in the Fleet Manager shows one of the following errors:

RPM request timed out

BACnet/IP error for tag <tag>: object, code: unknown-object

Firmware 3.29 brings significant changes to the way BACnet/IP works within the edge gateway and adds support for BACnet Device IDs. As a result of these changes, some BACnet/IP setups might stop working correctly (as mentioned in the release notes). Setups that are most likely impacted by these changes are ones where there is a BACnet device in-between the IXrouter3 and the machine, usually called a BACnet router.

For example, a device that translates BACnet MS/TP to BACnet/IP that is placed in-between the IXrouter3 and a BACnet MS/TP device.

In the data source settings in the Fleet Manager, change the data source's Addressing method from IP address to Device ID. It is important that the BACnet Device IDs are unique per device in your BACnet network. If there are duplicates, it will not work.

For help in finding your BACnet Device IDs, see How do I find my BACnet Device ID?. For help in changing a device's BACnet Device ID, please contact the manufacturer or consult their documentation.
