Module 3 – Construction of the switching mechanism
Learning objective
Understand and apply the state machine and its elements (State, Decision, Timer, Repeater, Jump).
Explanation
The state machine is the clock.
It operates according to the rule:
IF (AR = 1 AND ¬I AND ΣS = 0) THEN Next State.
The elements:
State: logical step with actions,
Decision: branching,
Timer: time-based state,
Repeater: repetition,
Jump: direct jump to a defined state.
Exercise
Draw a state machine with the states:
"Waiting for start", "Cylinder moves", "Waiting for sensor", "Return to home position".
Mark where a timer, decision or jump would make sense.
