Zusammenfassung:	The control/command system includes a control circuit (4) which takes over from a main switching member (3) in the event of a fault in the latter. The control circuit (4) having detected such a fault, applies to a fallback output (R), signals representing the input signals (En, Es) of the system and applies these signals to the output (So) of the system by way of an auxiliary switching member (5) which it controls. The control circuit also monitors the proper operation of automata (1, 2) connected upstream of the system and provides at its output (So) a fallback position in the event of a fault in these automata. It also tests itself.
