BACnet Broadcast Management Device BBMD (B3060)

  • Acts as a stand alone BACnet Broadcast Management Device. 

    A BBMD relays BACnet/IP broadcast messages within a BACnet/IP network that spans multiple IP subnets.

    Does what it is supposed to do...  easy web-based setup and great compatibility.

    BBMD diagramme

    A BBMD is a "BACnet/IP Broadcast Management Device" and is used to distribute BACnet broadcast messages throughout a BACnet/IP network consisting of interconnected TCP/IP sub-networks. A BBMD forwards BACnet/IP broadcast messages sent by devices connected to its subnet to peer BBMDs. Upon arrival at a destination BBMD, the message is then re-broadcast on that subnet. BACnet/IP broadcast messages are also sent to registered BACnet/IP Foreign Devices.

    The B3060 BBMD functions only as a BBMD. It does not perform BACnet routing, and it is not designed for use with network address translation (NAT). B3060 supports up to 140 BBMDs.

    The B3060 is optimized for high bandwidth usage due to its 32-bit embedded Linux-based OS and our BACstac/32TM protocol stack. This BACnet software is extremely robust and is the leading third party BACnet software used in thousands of devices from prominent industry manufacturers. 

    IP network support:

    • Web server for commissioning and troubleshooting
    • Statistics page for diagnostics
    • Secure login to web configuration and status interfaces
    • BACnet/IP Broadcast Management Device (BBMD)
    • Foreign Device Support (FDS)

    Standard Communications:

    • 10/100/1000 Mbps Ethernet.
    • Convenient Installation
  • The BBMD uses two Ethernet ports—one for the connection to a BACnet/IP network and a dedicated port for configuration. It is easily configured via web pages. The router is housed in a metal case and is powered by a 12 VDC external power supply.

    You can save the BBMD’s configuration in an offline file and reload at any time as needed. The status page provides a valuable tool for troubleshooting—you can see the  network traffic statistics, communication and interface statuses.

    BACnet utilizes broadcast messages for certain functions, such as when you try to discover BACnet devices.

    Routers join IP networks together so messages from one network can be sent to another. If your BACnet devices are interconnected via IP routers then these broadcast messages will, normally, be blocked by the IP router.

    To solve this problem BACnet provides a technology called BBMD – BACnet/IP Broadcast Management Device - and Cimetrics developed a stand alone BBMD which serves just this one purpose. It is very simple to use. The user installs B3060 on each network. Then he/she configures the B3060 by specifying the IP Address and mask of each BBMD in the B3060's BBMD table. This makes both BBMD configurations identical. When the one BBMD receives a broadcast, it forwards the messages to the other BBMD which in turn re-broadcasts on the other network. They are configured by BDT files and these may be modified on the fly using selected Bacnet services.The technology also provides for foreign device registration. This allows a device on one network to communicate with a device on another network by using the BBMD to forward and route the messages. B3060 also works with BBMD devices from other vendors.

Q: What is the BACnet IP character set that this device uses?

A: The BBMD device only forwards the valid BACnet packets across the IP Subnet and does not check or validate the payload (contents of the packet). Therefore, you need not be concerned about the supported character sets.

Q: Hello, I have a BBMD box (B3060), but it will not activate my configuration. The status in the bottom left corner says

A: Hello, Please save changes and reboot. Upon reboot, your changes must be reflected in your settings.
