Chapter 11: Building Automation and Control Network (BACnet)
Building Automation and Control Network (BACnet) is a written specification that includes the type of cable to be used - through to instructions on how to initiate a particular information request or command. Its rules are specifically designed for building automation and control equipment, covering such tasks as how to request a temperature reading, send a status alarm or establish a fan schedule.
Originally developed under the auspices of the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) BACnet has become an ISO and ANSI standard. A key feature of BACnet is its wide range of interoperability, ranging from simple information exchange to complex interoperation between competing components, devices and systems.
