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
