A method operates a safety-critical system, which system contains at least one first data device having approved, safety-relevant software and at least one reference data device having the same approved, safety-relevant software. In the method, after a type check of the system, the at least one first data device is equipped with at least one piece of non-safety-relevant additional software and the at least one reference data device is blocked from software modifications. Before safety-related data information is output, output information of the at least one first data device and of the at least one reference data device are checked for a match with regard to the safety-relevant software by a comparison device, and the safety-related data information is output in the case of a match.
