The "Normalize" instruction normalizes the value of the tag at input VALUE by mapping it to a linear scale. You can use the MIN and MAX parameters to define the limits of a value range that is applied to the scale. The result at the OUT output is calculated and stored as a floating-point number depending on the location of the value to be normalized within this value range. If the value to be normalized is equal to the value at the MIN input, the OUT output has the value "0.0". If the value to be normalized is equal to the value at the MAX input, the OUT output has the value "1.0".

Scale X

The "Scale" instruction scales the value at input VALUE by mapping it to a specified value range. When the "Scale" instruction is executed, the floating-point value at the VALUE input is scaled to the value range that was defined by the MIN and MAX parameters. The result of the scaling is an integer, which is stored in the OUT output.

In short: with Norm_X input formatcan be selected, output is always a real.
with Scale_X input is always a real, output formatcan be selected.
