Example:
When B0005 is ON, the data of D0125 is compared with the constant data 0, and if the data of
D0125 is not 0, B0020 is turned ON.
If the data of D0125 is 10, the comparison result is true. Consequently, B0020 is turned ON.
If the data of D0125 is 0, the comparison result is false. Consequently, B0020 is turned OFF.
Note
This instruction interprets the data as signed integer (-32768 to 32767).
