Cause

The AS has detected a b3 device with the same serial number in the hardware folder.

Resolution

Associate the device in the hardware folder with the device that you are trying to commission by dragging the device in the hardware folder and dropping it on the device under the BACnet interface that is being commissioned.

Note that the device's model numbers MUST be exactly the same in order for the association to succeed.
