Figure 58. BACnet device ID
BACnet networks without a Tracer
controller
On BACnet networks without a Tracer
controller, the Device ID can be assigned one of two ways:
• It can be the same number as the MAC Address,
determined by the rotary address dials on the UC400-B
controller. For example, if the rotary address dials are
set to 042, both the MAC Address and the BACnet
Device ID are 042.
• It can be soft set using the Tracer
the BACnet Device ID is set using the Tracer

BACnet networks with a Tracer
On BACnet networks with a Tracer
the Device ID for the UC400-B controller is always soft set
by the system controller using the following scheme
illustrated below.
Note: The BACnet Device ID is displayed as the Software
Device ID on the Tracer
page in the Protocol group.
