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.

//Scaling conversion data set
D3000=K4

The output value is calculated from the setting value of Point 0 and 1
X
since the input value "-65000" is between Point 0 and 1.
(-60000 - (-70000))
Output value = -70000 +
(-40000 - (-100000))
= -64166.666...
A fractional portion is rounded down.
