Abstract

A safety module for an automation system including a communication interface, which is configured for a signal-transmitting connection to a communication system including an output interface, which is configured for a signal-transmitting connection to consumers, which can be attached downstream, and including a processing device which is connected to both interfaces and is configured for processing communication signals from the communication interface and for providing processing results as output signals at the output interface. The processing device is configured such that a safety-related output signal is provided at the output interface if a safety signal, which is contained in a communication signal, is present, and if at least two data records, which are respectively provided in a communication signal, are encoded differently and are directed at the processing device, conform with one another.
