Precautions for Correct Use

The input variable is not allowed to omit. An error will occur during the compiling of the software if
the input variable is omitted. But the output variable is allowed to omit.

The value of Out varies between 0 and
π
when the value of In changes between -1.0 and 1.0. The
instruction will not go to the error state if the value of In is out of -1.0 ~1.0 and the value of Out is
nonnumeric.

Programming Example

The data types of variables ACOS_In and Out1 are REAL and LREAL respectively. The value of
Out1 is 0 if the value of ACOS_In is 1.0 when ACOS_EN changes to TRUE. The value of Out1 is
3.14159265358979 as ACOS_In is -1.0.
