BACnet Interface - Multi-State Value Object - Value of Lamp, Group and Channel
Multi-State Value Object - Value of Lamp, Group and Channel
Some Lamps, Groups and Channels parameters are also available via these objects. Those values are also available via the properties values of the associated Analog Output object.
As Multi-State Value Present_Value starts at one (1), see the Present Value section since the values of this object may be different from the associated property values of the Analog Output object.
