Example:
When B0005 is ON, the data of D0125 is compared with the constant data 2500, and if the data
of D0125 is greater than 2500, B0020 is turned ON.
If the data of D0125 is 3000, the comparison result is true. Consequently, B0020 is turned ON.
If the data of D0125 is -100, the comparison result is false. Consequently, B0005 is turned OFF
Note
This instruction interprets the data as signed integer (-32768 to 32767).
