2. 32-bit operation (DSCL/DSCLP)
The input value specified by is processed by scaling for the specified conversion table, 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.

3. Setting the conversion table for scaling
The conversion table for scaling is set based on the data table stored in a device specified in and later.
The data table has the following configuration:
→ For a setting example, refer to the next page.
