Arithmetic instructions

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.

In the DUT Pool, the number of reference points and the xy value pairs are declared.

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

Here the input variable measured_value was declared, corresponding to the type of the DUT

defined above. Assigning the x values and y values was done in the POU header. However, you

can change the x values and y values in the body by assigning a value to the variable, e.g.

Measuredvalues.Y_Values[3] for y3.

When the variable start is set to TRUE, the function is carried out. For the input value at position

x, the output value y is calculated via linear interpolation between the neighboring reference points

stored in the variable measured value.

F283_DSCAL(input_value, measured_value.referencepoints, output_value);
