BACnet


Overview
BACnet is a communications protocol for building automation and control networks. 
The BACnet protocol defines a number of services that are used to communicate between building devices. The protocol services include
  • Who-Is (Object Identifier)
  • I-Am, (Object Type)
  • Who-Has, (Services offered) 
  • I-Have, (Properties such as Counters, States, environmental variables) 
Taken together, these are used for Device discovery and management. Services such as Read-Property and Write-Property are used for data sharing. The BACnet protocol defines a number of Objects that are acted upon by the services. The objects include Analog Input, Analog Output, Analog Value, Binary Input, Binary Output, Binary Value, Multi-State Input, Multi-State Output, Calendar, Event-Enrollment, File, Notification-Class, Group, Loop, Program, Schedule, Command, and Device.
