Device ID Assignment for Base Tracer

SC+s

For unit controllers installed using a Base Tracer

SC+, the Application Tracer

SC+ calculates the device

ID using the BACnet

network number of the Base Tracer

SC+ MS/TP link and the rotary switch value

of the unit controller.

The following example in Table 4 illustrates this process.

Device ID Assignment for Wireless Devices

For devices connecting over a wireless network, Tracer

SC+ calculates the device ID using the BACnet

network number and the rotary switch value of the wireless device.

The following example in Table 5 illustrates this process.

Customizing Device IDs

For complex BACnet

addressing schemes or prescribed job specifications, custom device IDs may be

required. You can customize the device IDs of Tracer

unit controllers by using the Tracer

TU service

tool. During the device installation process in Tracer

SC+, select the “Preserve the predefined BACnet

device ID of the unit controllers being installed” checkbox (Figure 10, p. 18). As a result, the installed

devices will retain their device IDs. This feature applies to Trane and non-Trane BACnet

devices.
