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.
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 [ +1, ] and
later.
The data table has the following configuration:
→ For a setting example, refer to the next page.
Setting example of the conversion table for scaling
A setting example for the 16-bit operation is shown below.
For the 32-bit operation, set each item using 32-bit binary value.
In the case of the conversion characteristics for scaling shown in the figure below, set the following data table.
