Processing details
• These instructions scale the scaling conversion data (16-bit data) in the device specified by (s2) on the basis of the input
value in the device specified by (s1), and stores the operation result in the device specified by (d). Scaling conversion is
performed based on the scaling conversion data stored in the device specified by (s2) and later.
Setting item (n is the number of coordinate points specified
by (s2).)

• If the operation result is not an integer, the first decimal place is rounded off.
• Set the X coordinate data of the scaling conversion data in ascending order.
• Set the value in (s1) within the range of the scaling conversion data (device value in (s2)).
• If two or more points indicate the same X coordinate, the Y coordinate value of the largest point number is output.
• Specify a value from 1 to 65535 for the number of coordinate points of the scaling conversion data specified by (s2).
