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 ≥ Constant -100 R020 is OFF
Note
• This instruction deals with the data as signed integer (-32768 to 32767).
