POU header All input and output variables used for programming this function have been declared in the POU
header.
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.
Body When the variable start is set to TRUE, the function is carried out. The constant 3 (lower limit of
the deadband) and 10 (upper limit of the deadband) are assigned to inputs s1 and s2. However,
you can declare variables in the POU header and write them in the function in the body at the
inputs.
