Program example
■Program which sets 4 points of scaling conversion data to D3000 to D3009 and substitutes the
output value, which is positively converted based on the input value "7500", to D3106
16-bit scaling
[F10]
//Scaling conversion data set
D3000=K4 //Number of point=4
D3001=K0 //Unusable area
//Set the point 0 to 3
D3002=K0 //Point 0
D3003=K1000 //(X0, Y0)=(0, 1000)
D3004=K2000 //Point 1
D3005=K3000 //(X1, Y1)=(2000, 3000)
D3006=K4000 //Point 2
D3007=K6000 //(X2, Y2)=(4000, 6000)
D3008=K10000 //Point 3
D3009=K7000 //(X3, Y3)=(10000, 7000)
[G10]
X0 //Standby until X0 turns ON
[F20]
//Positive conversion execution (Output value is
stored in D3106)

The output value is calculated from the setting value
of Point 2 and 3 since the input value "7500" is
Point 3
