simple logic test

almost sounds like my test

In one job interview that I had they took me out to one of there production machines and gave me a laptop. I had to open up RSLinx and RSLogix 500 and get online with the PLC. Once I was online they asked me why a bit in the program wasn't energized and I had to trace the logic back and tell them what was not turned on for the bit to be true.
I did the same thing, had them hookup to a PLC and trace a circuit and discribe it.
