4.4.13. Map Descriptor Example 10 - Binary Value (Zone and Area Machine)
A read from the Binary Value Data Array which is shared by a BACNet IP Map Descriptor will return the current value of a
system variable in the Lutron eLumen panel. The value returned is inactive (0) if the system variable is zero and active (1) if
non-zero. The Lutron Machine Map Descriptor regularly polls the Lutron panel to retrieve the system variable values. A write
to the Binary Value Data Array will set the system variable to 255 on active (1) write or to zero on inactive (0) write.

The ARCO function is the same as RDBC except that the length of the Map Descriptor is taken as the number of system variables to
poll. The start system variable number is specified under the “Sys_Var” Map Descriptor field. More than one ARCO Map Descriptor
may be used to poll two series of system variable 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.
