ADLINK PCI-8164 - Manual (Page 149)

Operation Theory 137
The Value block in this figure is the position where the comparison
occurs, and where the data can be checked by using
_8164_check_compare_data().
Note that at the final compared point, load an After-final point into
the Value block. Fill a dummy point into the comparison table array
at the final position. This value must be far enough from the table’s
stroke.
If using _build_compare_function(), a dummy “after-final”
point is automatically loaded. This value is equal to (End point +
Interval x Total counts) x moving ratio.
