BACnet
BACnet (Building Automation and Control Network) is a communications protocol that defines the services used to communicate between building automation end-devices and building control systems. The BACnet protocol specification like all protocol specification defines both how data is represented on the network and the services that are used to move data from one BACnet node to another. It also includes messages that identify data and network nodes such as Who-Is, I-Am, Who-Has, and I-Have.
The BACnet protocol is a completely non-proprietary open communication software standard. There are no proprietary chip sets or special electronics required to implement it. The standard itself is now controlled by the ANSI (American National Standards Institute) and ASHRAE (American Society of Heating Refrigeration and Air-Conditioning Engineers) Standard 135- 1995. BACnet stands for Building Automation and Control network. The BACnet Committee developed the standard with the intention of creating a technically sound and truly non-proprietary standard. They also kept in mind ease of use and did their best to eliminate many of the barriers to implement. In June of 1995, after years of industry input ASHRAE adopted BACnet as a standard for the Building Automation industry.
