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.

Zone_vara_0,	Analog_Value,	0,	Passive_Client,	LUT_GRF6_0,	sys_var_val,	0,	512

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.
