    Hi All,

    I am struggling to read an on-board Analog input of a PM564 ABB PLC.
    Using Codesys, the input (AI0) is acting as a normal digital input.

    Can any one assist...
    Thanks

    Never used ABB, but what is the symptom, does the analogue input show a digital value regardless of the input voltage or does it change at all?

    not familiar with the programming of the abb, but the plc's I have worked on require you to set up the input as an analog input, instead of an on off switch input. assign the input properly.
