building automation control network (BACnet)

Building Automation Control Network (BACnet) is a standardized networking concept for building automation that was developed for communication between controllers, sensors and actuators and is based on a layer model. The physical layer and the data link layer support various transport media and communication technologies, for example with fieldbuses such as the Local Operating Network (LON) or Ethernet

. BACnet recognizes data objects that must be transported from a sender to a receiver without precisely defining the interface and transport mechanisms. Since control processes in building automation tend to be slow, it does not matter whether one uses Ethernet via tunneling or encapsulation, nor whether one uses the UDP protocol or the TCP protocol as the transport protocol. The BACnet protocol was developed by an American association for building automation and adopted by the International Organization for Standardization (ISO) and the German Institute for Standardization

(DIN). In Europe,

the BACnet Interest Group Europe (BIG EU) represents the interests of BACnet users and is responsible for the further development of BACnet.
