Management Device (BBMD) and Foreign Device for intranetwork connectivity.

BBMD Settings
BACnet/IP devices send broadcast discovery messages such as “Who-Is” as a means to discover
other BACnet devices on the network. However, when there are two or more BACnet/IP subnetworks,
broadcast messages do not pass through network routers that separate these subnetworks.
BBMD allows broadcast message to pass through a router: on each subnet, a single device has
BBMD enabled. Each BBMD device ensures BACnet/IP connectivity between subnets by forwarding
broadcast messages found on its subnetwork to each other, and then onto the local subnetwork as a
broadcast message.
In the BBMD table, add the BBMD-enabled controllers located on other subnetworks. To add a BBMD:
1. Click .
Figure34: Adding a BBMD
2. In the IP field, enter IP address of the BBMD located on the other subnetwork.
3. In the Mask field, enter the subnetwork mask for the other subnetwork.
4. In the Port field, enter the port number for the BACnet service of the BBMD located on the other
subnetwork.
5. Click OK.
You can also edit or delete a BBMD selected from the list using the Edit icon or Delete icon
provided.
