29 Data Table Operation – FNC250 to FNC269
29.7 FNC269 – SCL2 / Scaling 2 (Coordinate by X/Y Data)
29.7 FNC269 – SCL2 / Scaling 2 (Coordinate by X/Y Data)
Outline
This instruction executes scaling of the input value using a specified data table, and outputs the result.
SCL (FNC259) is also available with a different data table configuration for scaling.
SCL2 instruction is supported in the FX
3UC Series Ver. 1.30 or later.
→ For SCL (FNC259) instruction, refer to Section 29.4.

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.
Operand Type Description Data Type
