BACnet Object Names When an external BACnet Client builds a list of Object Names, the BACnet Server Map Descriptor name determines the BACnet Object Name. If the Map Descriptor length is greater than 1, then the Object Name will be suffixed with the index into the Map Descriptor. For example, if the Map Descriptor name is SMD_AI_01 and the length 3, then the Object Names will be SMD_AI_01[0

Debugging a BACnet connection: Hints and tips • Disconnect the FieldServer from the BACnet network when transferring images to the BCU. • If duplicate object instances are accidentally configured in the FieldServer, the second call of the instance will overwrite the first one. This may cause a BACnet Object to be “lost.” • If “Virtual_BCU_…” is not being indicated as the device desc
