Hi
I have a question about ladder programming (in visilogic):
MI1 is coming from a keypad entry, the value range is 0-100.
MI2 is coming from an analog input, and is already scaled to the range 0-100.
How can i force MI1 to #0 if MI2<20. The MI1 should not be changable by the keypad when MI2<20.
Sorry for such a easy and maby silly question.
