A Ladder Diagram PLC program designed to interpret the quadrature pulse signals is shown here, making use of negative-transition contacts as well as standard contacts: The counter will increment (count up) when sensor B de-energizes only if sensor A is already in the de-energized state (i.e. light beam A breaks before B).
Color-highlighting of Ladder Diagram components only works, of course, when the computer running the program editing software is connected to the PLC and the PLC is in the "run" mode (and the "monitor" feature of the editing software is enabled). Otherwise, the Ladder Diagram is nothing more than black symbols on a white background.
Even today, a lot of the conventions that led to "ladders" are still in use, and I will use a recent example drawing to illustrate this. Below is a simplified drawing of a control circuit and one of our ladder logic diagram examples. The appearance is what led to being called ladder logic, since it superficially resembles a ladder.
