In this example, the same POU header is used for all programming languages. For an example

using IL (instruction list), please refer to the online help.

All input and output variables used for programming this function have been declared in the POU

In this example, the input variable input_value is declared. However, you can write a constant

directly at the input contact of the function instead.

The constant -1.23 is assigned to input s1 (negative offset) and the constant 5.55 is assigned to

input s2 (positive offset). However, you can declare two variables in the POU header and write

them in the function in the body at the inputs. When the variable start is set to TRUE, the function

is carried out. Since the input_value is negative (-10.0), the negative offset -1.23 is added to it.

The result here is: output_value = -11.23.
