Examples of programs for the implementation of a traffic light

Perhaps some of the beginners will benefit from examples of programs developed on two popular tool environments Step7 (Siemens) and CodeSys

It seems to be simple, blinked one color, then another. But even in this case, you can not do without triggers, self-locking circuits, the use of timers and other things.

In the first case, the program is executed in the language of ladder diagrams, in the other case in the pascal-like language ST.
