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.

D0125

0

³Constant

-100

R020 is OFF

Note

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