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 10 and that of D0040 is 15, the comparison result is true. Consequently,
B020 is turned ON.
If the data of D0125 is 0 and that of D0040 is -50, the comparison result is false. Consequently,
B020 is turned OFF.
Note
This instruction interprets the data as signed integer (-32768 to 32767).
