What does BACnet over IP mean?

Internet Protocol
The “IP” in BACnet over IP is “Internet Protocol,” one of the main protocols that allow computers to talk with each other over a network. BACnet over IP allows for communication between different IP subnets, multi-campus control systems, and can even use fiber and gigabit-ethernet.

Is Ethernet IP the same as BACnet IP?

Ethernet and IP are relatively similar, as they aren’t dependent on token passing. IP is routable, but requires a BACnet Broadcast Management Device (BBMD) on each subnet to send messages across the network.

What is BACnet network number?

A BACnet/IP network is a collection of one or more IP subnetworks (IP domains) that are assigned a single BACnet network number. A BACnet internetwork (3.2. 26) consists of two or more BACnet networks. These networks may be BACnet/IP networks or use the technologies specified in Clauses 7, 8, 9, or 11.

Is BACnet TCP IP?

BACnet/IP uses the User Datagram Protocol (UDP), a connectionless protocol. TCP, a connection-oriented protocol, has significantly more overhead than UDP and does not allow “one-to-many” messages. Other stream oriented protocols, such as ATM, suffer from the same problem.

What is BACnet used for?

BACnet is “a data communication protocol for building automation and control networks.” A data communication protocol is a set of rules governing the exchange of data over a computer network that covers everything from what kind of cable to use to how to form a particular request or command in a standard way.

How does BACnet work?

BACnet works by dividing the problem of interoperability into three distinct areas, and by defining methods and standards for implementing each. BACnet devices actually exchange information and do things by sending and receiving electronic messages containing this coded application language.

What is the BACnet / IP protocol used for?

BACnet/IP protocol allows communication between the components of a building automation and control system (for example, HVAC, lighting control, security systems and related equipment). The BACnet/IP protocol defines a number of services that are used to communicate between devices and the objects that are acted upon by those services.

What is the definition of a BACnet device?

A simple definition of a BACnet device is a collection of objects that represent the functions present in a real device. This is why virtual devices can be considered a BACnet device as well as physical controllers.

What does a BACnet / ip-pm5300 do?

A BACnet/IP device (or software application) that resides on a remote IP subnet and registers with a BBMD to facilitate the sending and receiving of broadcast messages to/from devices accessible by the BBMD.

Which is BACnet device forwards bbmds messages?

A BACnet/IP device (or software application) residing on a BACnet/IP subnet that forwards BACnet broadcast messages from devices on its subnet to peer BBMDs and registered foreign devices on other subnets.
