All BACnet Open controllers must have a unique Device Instance and Name. These BACnet addresses are
automatically generated and usually do not require modification. However, sometimes you need to override the
automatic addressing assignments.
Autogenerated addressing scheme:
The Carrier® ChillerVu™'s rotary address setting determines the automatic BACnet addressing scheme for the
connected Open network.
16 = Carrier's BACnet Vendor ID
xx = Carrier® ChillerVu™'s rotary switch address (BACnet Device Instance address)
yy = Open controller's rotary switch address (MS/TP MAC address)
For the Carrier® ChillerVu™:
• BACnet Device Instance Number = 1600xx
• BACnet Device Instance Name = device1600xx
• BACnet IP Network Number = 1600
• BACnet MS/TP Network Number = 161xx
• BACnet ARC156 Network Number = 163xx
• Port S1 MS/TP MAC Address = 0 (fixed)
For the Open controllers connected to the Carrier® ChillerVu™
• BACnet MS/TP Device Instance Number = 161xxyy
• BACnet ARC156 Device Instance Number = 163xxyy
• BACnet MS/TP Device Instance Name = device161xxyy
• BACnet ARC156 Device Instance Name = device163xxyy
• BACnet MS/TP or ARC156 MAC Address = yy
• BACnet MS/TP Network Number = 161xx (learned from the router, defaults to 16101 if no Carrier®
ChillerVu™ is operating)
If the BACnet automatic settings need to be changed, launch the
utility using a terminal
program. See To assign a custom IP address for instructions on connecting to and using a terminal program.
