When R00C is ON, the data of D0125 is compared with the data of D0040, and if the data of
D0125 is less than the data of D0040, R020 is turned ON.
If the data of D0125 is 43000 and that of D0040 is 45000, the comparison result is true.
Consequently, R020 is turned ON.
D0125 43000 < D0040 45000 R020 is ON
If the data of D0125 is 50000 and that of D0040 is 50000, the comparison result is false.
Consequently, R020 is turned OFF.
D0125 50000 ≥ D0040 50000 R020 is OFF
Note
• This instruction deals with the data as unsigned integer (0 to 65535).
