BACnet points are not updating in the UNC after the replacement of a BACnet device.

Issue

BACnet points are not updating in the UNC after the replacement of a BACnet device.

Product Line

TAC I/A Series

Environment

Niagara R2, UNC 520

Cause

Tech replaced a drive from one manufacturer with a drive from a different manufacturer. The BACnet device object in the UNC was reused. Since the replacement drive was not the same model or manufacturer as the one being replaced, the BACnet points between the two devices are different. The points in the replacement device do not match the points in the reused BACnet device object in the UNC.

Resolution

The solution would be to delete the BACnet device object in the UNC, discover the replacement device and learn it into the UNC.
