Hi, I'm trying to develop logic to enable me to punch in a four digit number into a 16 button keypad, and read the numerical result in an
integer or string of a micrologix 1500. I'm pretty sure I have to sequentially scan either the rows or columns and match them up with their
opposites. An example of full ladder logic would be very much appreciated if possible.
Thanks and regards
