Segundo a documentação do protocolo BACnet:

Defines a standardized object whose properties represent the externally visible characteristics of a multi-state value. A "multi-state value" is a control system parameter residing in the memory of the BACnet device. The actual functions associated with a specific state are a local matter and not specified by the protocol. For example, a particular state may represent the active/inactive condition of several physical inputs and outputs or perhaps the value of an analog input or output. The Present_Value property is an unsigned integer number representing the state. The State_Text property associates a description with each state.
