Appendix A: Configuring Tracer UC600 for BACnet/IP
Tracer UC600 controllers with firmware versions 5.0 or higher now support the BACnet/IP protocol.
This appendix provides Tracer UC600 configuration information to enable communication using
the BACnet/IP protocol.
Device ID Assignment for Trane BACnet/IP Devices
Each unit controller must have a unique BACnet device ID. Tracer SC automates the device ID
assignment process for Trane unit controllers by calculating a unique device ID for each unit
controller and then saving the device ID to memory in each device.
Manual configuration (soft set) of the BACnet device ID requires the use of Tracer TU or the free
Tracer BACnet Setup tool. See
“Configuring Tracer UC600,” p. 46
.
For devices communicating over BACnet/IP, Tracer SC calculates the device ID using the BACnet
network number defined for Ethernet port 1 and the unit controller rotary switch value. The Tracer
SC rotary switch value is not used in the device ID calculation for IP devices.
BACnet/IP device IDs are calculated using the following two sets of values:
•
The BACnet network number Ethernet port number 1
–
Tracer SC defaults the BACnet IP network number as 1, and under most circumstances it is
not changed.
•
The unit controller rotary switch value (1 to 999).
The values are joined together to form the BACnet device ID for the unit controller.
The following example in
illustrates this process.
Ethernet Network Wiring Specifications
The Ethernet port supports 10BaseT and 100BaseT Ethernet networks and requires Cat5, Cat5e, or
Cat6 rated communication wire. The maximum rated distance between nodes on the network
is 100 m. The minimum distance between two devices is 0.5 m.
Note:
Cable installations must comply with both national and local codes. Plenum-rated cable is
available to meet NEC Article, which addresses flame resistance and smoke emission for
signal cables.
Important:
Due to the high precision required when performing Ethernet wire terminations,
Trane recommends that only qualified technicians with the proper equipment handle
all terminations and splicing.
BACnet/IP Network Configuration on the Tracer SC
Important:
IP configuration must be completed before device discovery and installation.
Tracer UC600 supports BACnet BBMD functionality. If the Tracer UC600 is not located on the same
IP subnet as the Tracer SC, BACnet BBMD functionality must be enabled on the IP network.
The BACnet network number on Tracer SC Ethernet port defaults to 1 and should be suitable for
most installations. The BACnet configuration tab of the Tracer SC user interface can be used to
change the default BACnet network number if needed. For more information, see the “Tracer SC
IOM,” BAS-SVX31.
