Abstract: A method for a plausibility check of safety-relevant variables, wherein a first safety-relevant variable and a further safety-relevant variable are dependent on one another and are each provided to be raised from a lower safety level to a higher safety level. The plausibility check of the first safety-relevant variable is performed in a first time interval of a cycle of a clock by implementing a first plausibility rule, and upon a successful plausibility check during the first time interval, is raised from the lower safety level to the higher safety level for the safety-relevant variable. The plausibility check of the further safety-relevant variable is performed in a second time interval of the cycle of the clock by implementing a further plausibility rule, and upon a successful plausibility check during the second time interval, is raised from the lower safety level to the higher safety level for the further safety-relevant variable.
