This field
determines the
Map
Descriptor’s
function. See
Section 6.1.2
for more
information.
Required for Throttling Mode: This field specifies the
minimum change needed for a Network Variable’s
value to invoke an NV Update.
If found during Min_Scan_Time
sampling (Throttling Mode) that
Max_Scan_Time has elapsed since the
last NV Update, a new NV Update will
be transmitted.
For Non-Throttled
Client Map
Descriptors the
Scan_Interval
determines the
update rate.
The Data Array will be
sampled and evaluated for
delta change once every
Min_Scan_Time (seconds)
