Example:
When B0005 is ON, the data of D0125 is compared with the constant data 40000, and if the data
of D0125 is greater than 40000, B0020 is turned ON.
If the data of D0125 is 52000, the comparison result is true. Consequently, B0020 is turned ON.
If the data of D0125 is 21000, the comparison result is false. Consequently, B0005 is turned OFF.
Note
This instruction deals with the data as unsigned integer (0 to 65535).
