   * To start and stop running might be triggered by pressing or releasing a button connected to the critical input. In our simple example we do not have real hardware. Hence we simply start and never stop, because the state of the hypothetical input is always ''true''.    * To start and stop running might be triggered by pressing or releasing a button connected to the critical input.

   * When pressing ''Ctrl-C'' the system falls into level ''slShuttingDown''. A level action for this safety level causes the system to automatically switch to level ''slOff'' which then terminates the program. Here again, this would be signalled by the sequencer after a shutting down sequence has finished or by the control system as soon as a certain safe condition is reached.   * When pressing ''Ctrl-C'' the system falls into level ''slShuttingDown''.

-===== How to shut down ===== 
-The example demonstrates how the system should be stopped in a well controlled manner, see [[getting_started:tutorials:stoppingsystem|]].
