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 tur ned O N.
D0101×D0100 250000 ¹D0251×D0250 250000 R014 is ON
If t he data of D0101×D0100 is -100 and D0251×D0250 is -100, R014 is turned OFF.
D0101×D0100 -100 =D0251×D0250 -100 R014 is OFF
