A safety module for an automation system includes a communication interface designed for a signal-transmitting connection to a communication system, an output interface designed for a signal-transmitting connection to at least one user which can be fitted downstream and a processing device connected to the communication interface and the output interface and designed to process communication signals from the communication interface and to provide output signals to the output interface wherein the processing device is designed for a detection of an actual component behaviour, using a control command contained in a communication signal and a component measured value contained in a communication signal, and for a comparison of a presettable component behaviour to the actual component behaviour as well as for a provision of a safety-oriented output signal to the output interface at a presettable divergence between the presettable component behaviour and the actual component behaviour.

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.
