This field determines the Map Descriptor’s function. See Section 5.1.2 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.

The Data Array will be sampled and evaluated for delta change once every Min_Scan_Time (seconds)

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.
