This is accomplished by introducing "objects." An object is simply a collection of information related to a particular function that can be uniquely identified and accessed over a network in a standardized way.
All information in a BACnet system is represented by such data structures. The object concept allows us to talk about and organize information relating to physical inputs and and outputs, as well as non-physical concepts like software, or calculations.
Objects may represent single physical “points,” or logical groupings of points that perform a specific function. Objects meet the design requirement of providing each device with a common "network view," i.e., all objects, regardless of the machine in which they reside, look alike!
