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.

When the variable start is set to TRUE, the function is carried out. It adds the corresponding

positive offset value = 2 to the positive input value = 18. The constants 5 (negative offset) and 2

(positive offset) are assigned to inputs s1 and s2 respectively. However, you can declare variables

in the POU header and write them in the function in the body at the inputs.

F290_DZONE( s1_NegBias:= 5,

s2_PosBias:= 2,

s3_In:= input_value,

d=> output_value);

for an instant

(*5=neg. offset, 2=pos. offset *)

 the calculation results in an overflow or

an underflow of output d.

 the input value s3 is 0.
