Fig. 26 Calculating the MAC Address

Setting the Device Instance Number

The Device Instance number must be unique across the
entire BACnet™ MS/TP network because it is used to
identify the BACnet™ devices uniquely. It may be used to
identify the BACnet™ device from other devices during
installation conveniently. The BACnet™ MS/TP Device
Instance number is automatically set when added to a
Niagara station. The user can change the Device
Instance number.
