BACnet Setup Tool will not work with a UC800 and requires Tracer TU to changed baud rate and set the device ID.
  • Devices have a unique address, in this case an IP address, and they know what that address is. Devices do not know, or at least do not need to know, their BACnet network number (unless the device is a BACnet router). BACnet/IP uses the User Datagram Protocol (UDP), a connectionless protocol. Here is why UDP was chosen:
    • BACnet/IP predominantly communicates through broadcast messages, which are received by every device on the same network. Broadcasts are super important for discovering devices or finding and sharing new information. On big systems, though, you can’t have every device on every network sending and responding to broadcasts.
    • LonWorks to BACnet gateways, or protocol converters, translate LonWorks network variables into BACnet objects and translate BACnet objects into LonWorks network variables. The Babel Buster gateways will connect BACnet MS/TP or BACnet IP devices to a LonWork Free Topology network.
    • The BACnet Interface will provide up to 28 objects that can be monitored/controlled via the BACnet building management system (see the Interface for use in BACnet Design Guide -EDUS72-749B) Capable of controlling up to 64 indoor unit groups (128 indoor units) per DIII-Net port (2 DIII-Net ports standard).

    • A message addressed to all devices or nodes on all networks known any device on any network. BACpypes address objects are used as the source and destination for PDUs and are also keys to dictionaries for looking up device in information and organizing requests and responses with devices. Building an Address ¶
    • Some devices support MAC address modification through BACnet object/property, but before doing that, it should have a valid MAC address to join BACnet network. If the unique MAC address could be automatic obtained like we get IP address just by plugging notebook into home/office network, it would save a lot of time in commission.
    • A BACnet device goes offline and fails to come back online. A change of the BACnet device IP address. At startup of the supervisory controller, the BACnet Integration binds with the BACnet Object Identifier (OID) and uses the IP address from that bind.
    • The BACnet communication module connects the MicroTech III chiller unit controller to a building automation system (BAS). This interface enables the exchange of BACnet objects between the unit controller and the network.

  • BACnet devices communicate to one another over a network. The more popular networks include the Internet Protocol (BACnet/IP) and the Master-Slave Token-Passing network (BACnet MS/TP). Interconnecting BACnet networks requires BACnet routers while connecting non-compliant BACnet devices to a BACnet network requires a gateway.
    • With BACnet/Ethernet, LAN addressing is accomplished using the Ethernet’s media access control (MAC) address. The MAC address is the 48-bit worldwide unique value given to every Ethernet controller chip and not the 32-bit IPv4 address we would expect with an IP/Ethernet device. Of all the BACnet data links, Ethernet provides the greatest speed.
