Function and operation explanation
1. 16-bit operation (SCL2/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.
