4.4.5.Map Descriptor Example 2 - Binary Input (Zone Machine)
A read from the Binary Input Data Array which is shared by a BACNet IP Map Descriptor will return the relay state for the given zone. The Lutron Machine Map Descriptor regularly polls the eLumen panel to retrieve the value of zone intensity. The value of each BACNet object presenting Binary Output is inactive if the intensity is zero and active if the intensity is

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 Descriptor may be used to poll two series of zone numbers, eg. from
