Example
When R00C is ON, the data of D0125 is compared with the constant data 0, and if the data of
D0125 is not 0, R020 is turned ON.
If the data of D0125 is 10, the comparison result is true. Consequently, R020 is turned ON.
D0125
10
≠
Constant
0
R020 is ON
If the data of D0125 is 0, the comparison result is false. Consequently, R020 is turned OFF.
