[Setting data]
Setting data Description Data type of result
(S1)
Data which specifies the search/conversion method
0 Positive conversion by sequential search
1: Inverse conversion by sequential search
2: Positive conversion by binary search
3: Inverse conversion by binary search
—
(S2)
Input value for positive/inverse conversion
(S3)
Start device No. which stores the scaling
conversion data
(D)
Device No. which stores the conversion result
[Overview]
(1) 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 (XN-1, YN-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 < X1 <.....< XN-1, Inverse conversion: Y0 < Y1 <.....< YN-1)
(2) The calculation method for output value is the same as 16-bit integer type scaling.
(Refer to Section 5.16.1.)
POINT
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.
