Assume there are sixteen stations along a conveyor system.
The stations are numbered from 0-15 with station zero being the first (i.e. the point where parts enter the conveyor).
Parts are to advance along the conveyor at the rate of one station every four seconds.
A part may or may not be at a given station at any point in time.
An input sensor I:0.0/0 is used to detect a part entering the conveyor.
At station 5, parts are checked for defects and an input sensor I:0.0/1 is energized if the part is defective.
At station 10, any defective parts are to be removed from the conveyor by energizing output O:0.0/0.
