Abstract: A method and an arrangement having redundant systems operating in parallel in a cyclic mode and reciprocally checking a result of the task of the other system on a regular basis, and wherein one system is selected or confirmed for the productive mode in the fault situation found, where a characteristic variable concerning an operating parameter is picked up for each of the systems in multiple/all cycles and used for updating statistical parameters, where at least when a disparity between results of the two systems is found, a current operating parameter is correlated with the statistical parameter for each system, and where the system for which the current operating parameter differs from the statistical parameter less is detected as the correctly operating system and used for the productive mode such that the degree of fault coverage can be increased and hence the availability of the overall system increased.

Abstract: Apparatus and method for functionally securely transfer data in a two-sided data exchange of safety-related data between two communication partners (A, B), wherein a mapping is defined, which assigns to a consumer ID a provider ID of the same end point in the case of each bidirectional connection, and the mapping is made known to the two end points a priori, where the mapping could consist of the one's complement or alternatively of the two's complement, and wherein the connection between the data provider and the data consumer is established as described, the data consumer receives the address identification of the data provider via an additional side channel, for example, and after the connection has been established, the identification of the data provider can be securely checked.
