POU header All input and output variables used for programming this function have been declared in the POU
header.
In this example the input variables input_value and negative_offset are declared. However, you
can write constants directly at the input contact of the function instead.
Body When the variable start is set to TRUE, the function is carried out. It adds the corresponding
negative offset value = 10 to the negative input_value = -12. However, you can declare a variable
in the POU header and assign it to the function's input in the body.
