Segundo a documentação do protocolo BACnet:

Defines a standardized object whose properties represent the desired state of one or more physical outputs or processes within the BACnet device in which the object resides. 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 outputs or perhaps the value of an analog output. The Present_Value property is an unsigned integer number representing the state. The State_Text property associates a description with each state.
