Setting the BACnet Device ID
The BACnet device ID uniquely identifies each BACnet device. It can range from 0 to 4194303.
Device IDs cannot be shared among devices on the same network. Each Tracer UC600 operates as
a device and requires its own device ID, which defaults to the rotary switch value settings.
There are three ways that the BACnet device ID can be set on the Tracer UC600:
•
After powering up Tracer UC600 for the first time, the Tracer UC600 device ID will match the
rotary switch value.
•
When installing a Tracer UC600 on a Tracer SC, the Tracer SC will assign the BACnet device ID
based on the Tracer SC rotary address, the link number on which it is installed, and the Tracer
UC600 rotary switch value. For example, the Tracer SC will create a BACnet device ID of 101030
under the following conditions:
–
The rotary dials on Tracer UC600 are set to 30 (0,3,0), which is also known as the rotary switch
address.
–
The Tracer SC rotary switch value is “0,1,0”.
–
The Tracer UC600 is installed on link 1.
•
Soft set the BACnet device ID by using the Tracer TU service tool or the Tracer BACnet Setup
tool.
Important:
The Tracer UC600 BACnet device ID defaults to the value of the rotary switches if the
BACnet device ID has not been soft set. If a device ID has been soft set, the rotary
switches are no longer representative of the BACnet device ID.
Note:
When integrating Tracer UC600 with third party vendors refer to Tracer UC600 Protocol
Implementation Conformance Statement (PICS), (BAS-PRG010).
BACnet MS/TP Device ID Assignment
Each unit controller must have a unique BACnet device ID. Tracer SC automates the process by
calculating a unique device ID for each unit controller and then saving the device ID to memory in
each device.
BACnet MS/TP device IDs are calculated using the following three sets of values:
•
The Tracer SC rotary switch value (1 to 419)
•
The Tracer SC BACnet MS/TP link number (1 to 2)
•
The unit controller rotary switch value(1 to 127)
The three values are joined together to form the BACnet device ID for the unit controller.
The following example in
illustrates this process.
