Details
This function lists the existing scan list.
When you change a channel or scan attribute for an existing scan list item, the scan list is recreated
based on this change. If the scan list cannot be rebuilt, the scan list is lost.
To avoid unintentional changes to an existing scan list, configure channel and scan settings before
adding or creating a scan or step using the commands scan.add(), scan.addimagestep(), and
scan.create().
If the scan list is empty, the string "Empty Scan" is returned. Otherwise, the string lists each step in
the scan along with its information for step, open, measure configuration, count, and close (see the
example below).
