Analog vs group input

    If I have a PLC-Profibus-Robot setup. And I want to control the override with the plc.
    Then I can do this with a group input, make a register equal and override = Register. Is this also possible with an analog input?
    If yes, then why or in what situation is it better to use a group input?

    If you are using your full scale on your analog device I believe the AI[1] will read 0-1000. But don't quote me on that. Create a background program with no motion and program the following: R[x]=Ai[1] div 10. This will always put a value into the register because it runs in the background but will only change the robot when the override is changed in the looping program.

    Thx for the reply.
    So it is possible to use analog inputs for this. Then why should I bother to config group inputs, if I can just use virtual analog inputs for this?
    Is it because the max value is limited?
