Zusammenfassung:	The method which improves the integrity of electronic control systems involves the addition of an electronic device between the output of the control system and the logic system operating the actuator which executes the action required by the control system. An additional electronic system monitors the data reaching the logic system and compares it with the data sent out by the control system, enabling the failure in the transmission control systems to be detected and having a suitable action taken. This device is used in alarm and safety shutdown devices, especially in the nuclear reactors.
