4.4.14. Map Descriptor Example 11 - Analog Value (Zone and Area Machine)
A read from the Analog 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 variable values range from 0 to 255. The Lutron Machine Map Descriptors are regularly
updated with system variable values from the active Binary Value Map Descriptors. A write to the Analog Value Data Array will set
the system variable to the written value.

The Passive_Client function is used to prevent double-polling the Lutron eLumen panel for system variables. The Analog Value Map
Descriptors should be set up identical to the Binary Value Map Descriptors in terms of the Sys_Var and Length fields to ensure
system variable values will be stored correctly.
