What is BACnet?
- BACnet was developed in 1987 by a group of HVAC and Building Automation professionals as a standard, open protocol specifically for the building automation industry.
- BACnet stands for Building Automation and Control network.
- BACnet is a communications protocol that defines the services used to communicate between building automation end-devices and building control systems.
- BACnet defines both how data is represented on the network and the services that are used to move data from one BACnet node to another.
- BACnet can be used in all areas of building automation, including HVAC, Security, Access Control, Fire, Maintenence, Waste Management, Lighting, ect.
- BACnet supports multiple types of LAN which lends to its interoperability.
Data Object Properties
- All data in a BACnet system is represented in terms of “objects,” “properties,” and “services,” which gives BACnet the consistency to communicate with many different types of devices.
- Data is represented as objects, which are described in terms of 123 properties, while actions are carried out through 32 standard services.
