    Hi,
    I also use Wago controllers but I don't know witch library has scaling function.. .
    it's faster if you create a scaling function from your analog out value (%,....) and the "points".. ex: 0-4mA= 0-32767points..

    Made from your own it's like this:

    Out=(OutMax-OutMin) /(InMax-InMin)*(In-InMin))+OutMin

    Or you can find something already done into OSCAT into http://www.oscat.de/ library

    Regards

    in util.lib are several functions for this, i do use oscat for this, most i copy the txt version to keep the program small.
