4.6 Example – From the button to the cylinder

A simple example illustrates the connection:

1. Process: "Operator presses start button, cylinder extends."

2. Technology: Button = signal from input I0.0, cylinder = valve Q0.0 + sensor I0.1/I0.2.

3. Function: Button → IN zone, cylinder → IN_OUT zone.

4. SEQ: State 1 = "Waiting for start button" (S on IN zone), State 2 = "Cylinder extends" (S on IN_OUT zone).

That's all it takes – the state machine now knows both states and the zones know what they have to do.
