29 Data Table Operation – FNC250 to FNC269
29.7 FNC269 – SCL2 / Scaling 2 (Coordinate by X/Y Data)
Explanation of function and operation
1. 16-bit operation (SCL2 and SCL2P)
The input value specified in is processed by scaling for the specified conversion characteristics, and
stored to a device number specified in . Conversion for scaling is executed based on the data table
stored in a device specified in and later.
If the output data is not an integer, however, the number in the first decimal place is rounded.
→ For the method to set the conversion table for scaling, refer to the next page.
2. 32-bit operation (DSCL2 and DSCL2P)
The input value specified in [ +1, ] is processed by scaling for the specified conversion
characteristics, and stored to a device number specified in [ +1, ]. Conversion for scaling is
executed based on the data table stored in a device specified in [ +1, ] and later.
If the output data is not an integer, however, the number in the first decimal place is rounded.
