4.4.11. Map Descriptor Example 8 - Analog Input (Zone Machine)
A read from the Analog Input Data Array which is shared by a BACNet IP Map Descriptor will return the intensity to which a given
zone is set on the Lutron eLumen panel. The Lutron Machine Map Descriptor regularly polls the Lutron eLumen panel to retrieve the
zone intensities. The intensity value returned is scaled to a percentage value (0 to 100%). Zone numbers range from 0 to 511.

The ARCO function is the same as RDBC except that the length of the Map Descriptor is taken as the number of zones to poll. The
start zone number is specified under the “zone” Map Descriptor field. More than one ARCO Map Descriptors may be used to poll two
series of zone numbers, eg. from 5-10 and from 300-340. ARCO Map Descriptors with Length 1 fullfil the same function as RDBC
Map Descriptors with the same length.
