If your system has multiple routers that reside on different IP subnets, you must set up one router on each IP
subnet as a BACnet/IP Broadcast Management Device (BBMD).
Every subnet with a router must have a BBMD configured in order for broadcasts from controllers on that subnet
to reach the rest of the routers on the network.
NOTES
•
The i-Vu® Standard or Plus application - If the i-Vu® web server is on a separate subnet than the rest of the
routers, the internal router must be assigned an IP address and configured as a BBMD.
•
The i-Vu® Pro application - If the i-Vu® Pro server is on a separate subnet than the rest of the routers, you
must register it as a foreign device.
Use the
BBMD Configuration Tool
to:
•
Define the
Broadcast Distribution Table
(BDT) in each BBMD
•
Enable an i-Vu® Control System to find routers that are on different subnets
•
Allow controllers on one subnet to communicate with controllers on other subnets
•
Enable the i-Vu® application to see, upload, or configure controllers on different subnets
To set up BBMDs using the BBMD Configuration Tool
1
Assign an IP address, subnet mask, and default gateway for each Carrier® ChillerVu™ on the IP network. See
Addressing the Carrier® ChillerVu™.
2
Acquire the
BBMD Configuration Tool
from the Tech Tools DVD or from the
Carrier Control Systems Support
Site
. This is a stand-alone executable file and no installation is necessary.
3
Make a list of the IP addresses for each router that will function as a BBMD in your system.
In the above illustration, the Carrier® ChillerVu™, address 172.18.1.2, must be configured as a BBMD for the
172.18 subnet, while the Carrier® ChillerVu™, address 172.16.1.15, must be configured as a BBMD for the
172.16 subnet.
CAUTIONS
○
Define only one BBMD per subnet. Multiple BBMD's on an IP subnet disrupt network communications.
○
Unless explicitly modified, the UDP Port for BACnet/IP is 0xBAC0 (47808). Do not change this parameter
unless you made a change in the router.
4
In a text editor such as Notepad, create a list of the routers that will be BBMD's. List each IP address on a
separate line. (Maximum of 50 IP addresses per file)
5
Save the file to your folder of choice with a .bdt extension instead of .txt.
NOTE
".bdt" is a
Broadcast Distribution Table
file.
6
Open the
BBMD Configuration Tool
.
