Example:

When B005 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, B020 is turned ON.
If the data of D0125 is 43000 and that of D0040 is 45000, the comparison result is true.
Consequently, B020 is turned ON.

If the data of D0125 is 50000 and that of D0040 is 50000, the comparison result is false.
Consequently, B020 is turned OFF.

Note
This instruction deals with the data as unsigned integer (0 to 65535).
