7 APPLICATION INSTRUCTION
7.10 Data control instruction
Processing details
• These instructions process the scaling conversion data (in 32-bit data units) specified by (s2) by scaling it based on the
input value specified by (s1), and store the operation result in the device number specified by (d). The scaling conversion is
performed based on the scaling conversion data stored in the device specified by (s2) and later.
• If the operation result is not an integer, the number in the first decimal place is rounded off.
• Set the X coordinate data of the scaling conversion data in the ascending order.
• Set (s1) within the scaling conversion data range (device values of (s2) and (s2)+1).
• If the same X coordinate is specified by multiple points, the Y coordinate value of the point whose number is the largest is
output.
• Set the number of coordinate points for the scaling conversion data within the range of 1 to 4294967295.
