3.10 RANGE CHECK Instruction (RCHK)
[Outline]
The RCHK instruction checks whether the input value in the Input is within the Lower Limit and
Upper Limit, and then outputs the result to the bit output. The contents of the Input are retained.
Upper Limit
Lower Limit
Input
Bit Output=OFF
Bit Output=ON
Bit Output=OFF
If the Input value(Input) is greater than the Lower Limit and less than the Upper Limit, the
result(Bit Output) = ON.
• In the cases other than the above, the result(Bit Output) = OFF.
