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.

Safety module for an automation system, method for operating a safety module in an automation system and automation system

Control device having at least one electrical switching device, configured to provide electrical power to an associated load and arranged between a supply connection and a load connection and having at least one processing device, electrically connected with an input interface, with the at least one electrical switching device and with the load connection wherein it is provided that between the supply connection and the load connection parallel to the switching device an electrical resistor means is arranged, in order that when the switching device is open it forms a voltage divider with the load and allows a monitoring of the load connection independently of the switching state of the switching device.

Control device, automation system and method for operating a control device

A safety-oriented load switching device including a first current branch, which extends from a first supply connection to a first load connection and having a first switching means, and having a second current branch, which extends from a second supply connection to a second load connection and including a second switching means, wherein a first test branch is connected to a first measuring point located between the first switching means and the first load connection and is also connected to the second supply connection and includes a series connection of a first test switch and a first measuring device, wherein a second test branch is connected to a second measuring point between the second switching means and the second load connection and is connected to the first supply connection and includes a series connection of a second test switch and a second measuring device.
