5.3.15 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.
