1. A method of operating a system having multiple finite state machines and a controller connected to each finite state machine comprising the steps of: each finite state machine entering an offline state upon detection of anomalous operation; detecting at the controller whether all finite state machines have entered the offline state; upon detecting at the controller all finite state machines have entered the offline state, transmitting an online activation event signal from the controller to each finite state machine; and each finite state machine entering an online state upon receipt of an online activation event.
