Processing details
• 32-bit integer type scaling calculates the output value from the set input value based on the scaling conversion data where
a maximum of 2000 points data ((X
0
, Y
0
) to (X
N-1
, Y
N-1
), N: the number of points) are defined. The point data corresponding
to the input value should be set in ascending order. (Positive conversion: X
0
< X
1
<.....< X
N-1
, Inverse conversion: Y
0
< Y
1
<.....< Y
N-1
)
• The calculation method for output value is the same as 16-bit integer type scaling. (Page 161 When the input value is
between two points of scaling conversion data, Page 161 When the input value is not between two points of scaling
conversion data)
When the input value is outside the scaling conversion data or calculation result of output value is outside the
range of -2147483648 to 2147483647, an operation error will occur.
