Program example
■Program which sets 4 points of scaling conversion data to D3000 to D3017 and substitutes the
output value, which is positively converted based on the input value "-65000", to D3106L.

A fractional portion is rounded down.
The output value is calculated from the setting value of Point 0 and 1
since the input value "-65000" is between Point 0 and 1.
