Example
When R00C is ON, the data of D0125 is compared with the constant data -100, and if the data of
D0125 is less than or equal to -100, R020 is turned ON.
If the data of D0125 is -150, the comparison result is true. Consequently, R020 is turned ON.
D0125 -150
<
Constant -100 R020 is ON
If the data of D0125 is 0, the comparison result is false. Consequently, R020 is turned OFF.

Note
·
This instruction deals with the data as signed integer (-32768 to 32767).
