4.4.10.Map Descriptor Example 7 - Analog Input (Area Machine)
A read from the Analog Input Data Array which is shared by a BACNet IP Map Descriptor will return the last scene selected in a given area on the Lutron eLumen panel. The Lutron Machine Map Descriptor regularly polls the Lutron eLumen panel to retrieve the scene numbers.

//All values are in decimal ( 0 - 65535 )
//Insert a first available scene number under the Data_Array_High_Scale field for each Object ID or
//use the scale fields as desired to scale scene numbers.
//Object IDs are contiguous

The ARCO function is the same as RDBC except that the length of the Map Descriptor is taken as the number of areas to poll. The start area number is specified under the “Area” Map Descriptor field. More than one ARCO Map Descriptors may be used to poll two series of area numbers, eg. from
