Method, computer program product, computer program, storage medium with computer program stored thereon and computer system for safety-critical applications in machines, devices and / or systems

Method for safety-critical applications in machines, devices and / or installations, the method comprising the following steps: Receiving data (steps S10-S16) from the safety-critical process; Decoding (steps S20, S22, S44, S46) the received data in at least two processing environments (22, 42) by means of a coder object, each using a security time interval of the processing environments (22, 42); - calling (steps S24, S26, S34, S68) each an application program for processing the decoded data in the at least two processing environments (22, 42); Outputting (step S126) the processed data, wherein the at least two processing environments (22, 42) enable a time-diversity and / or data-diversity call and / or execution of an application program.
