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.
D0125

=Constant
0
R020 is OFF
Note
•This instruction deals with the data as signed integer
