When B0005 is ON, the data of D0125 is compared with the data of D0030, and if the data of
D0125 is equal to the data of D0030, B020 is turned ON.

If the data of D0125 is 3000 and that of D0020 is 3000, the comparison result is true.

Consequently, B020 is turned ON.

If the data of D0125 is -1500 and that of D0020 is 0, the comparison result is false.
Consequently, B020 is turned OFF.
