7.13 Data Control Instructions
7.13.5 Scaling (Point-by-point coordinate data) (SCL2(P),DSCL2(P))
(4) Set the input value within the range of the scaling conversion data (within the range of
devices).
(5) If some specified points have same X coordinates, the Y coordinate data of the highest point
number will be output.
DSCL2(P)
(1) This instruction executes scaling for the scaling conversion data (32-bit data units) specified
by with the input value specified , and then stores the operation result into the devices
specified by .
The scaling conversion is executed based on the scaling conversion data stored in the
device specified by and up.
(2) If the value does not result in an integer, this instruction rounds the value to the whole
number.
(3) Set the X coordinate of the scaling conversion data in ascending order.
(4) Set the input value within the range of the scaling conversion data (within the range of
and +1 devices).
(5) If some specified points have same X coordinates, the Y coordinate data of the highest point
number will be output.
(6) Specify the number of coordinate points of scaling conversion data from 1 to 32767.
When the coordinates of the scaling conversion data are set in ascending order,
the searching methods change from one to the other depending on the SM750
status. Therefore, the processing speed also change. The number of searches
determines the processing speed. Fewer number of searches make the
processing run faster.
For details, refer to Section 7.13.4.
