Example
When R010 is ON, the double-word data of D0101
⋅
D0100 is compared with the double-word
data of D0251
⋅
D0250, and if the data of D0101
⋅
D0100 is not equal to the data of
D0251
⋅
D0250, R014 is turned ON.
If the data of D0101
⋅
D0100 is 250000 and D0251
⋅
D0250 is 200000, R014 is turned ON.
