Device ID Assignment for BACnet/IP Devices
For devices communicating over BACnet/IP, Tracer SC calculates the device ID using the BACnet
network number for Ethernet 1 and the unit controller rotary switch value. For more details about
Tracer UC600 and the BACnet/IP protocol, see
“Appendix A: Configuring Tracer UC600 for BACnet/
The following example in
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
illustrates this process.
Rotary Dial Address Settings for Non-Trane Systems
The Max Master value defines the maximum allowable MAC address (rotary setting) on an MSTP
link. The rotary switch address is present in each device on the MSTP link. When the last
communicating device on the MSTP link polls for the Max Master MAC address with no response,
the token rotation will be restricted on the MSTP link.
For non-Trane systems, the Max Master value must be greater than the unique address settings
from the rotary dials. Although 999 is possible from the dials, the maximum allowed number by
BACnet is 127.
The Max Master is not adjustable in Tracer systems. For example, if the rotary switch address is
101 and the front-end system has a Max Master value of 100, the device will not be discovered.
Many systems have a minimum BACnet device ID value. Ensure that the device ID is greater than
this value.
