Abstract: Exemplary embodiments are directed to a safety module for connection to an automation device or automation system which is provided for control of safety critical and non-safety critical processes and/or plant components. The module includes a communication board that includes a processing unit which is connected via an input/output bus slave and an external input/output bus connected to a central processing unit, and one or more secure processing units arranged on one or more circuit boards having safety oriented input/output circuits for safety oriented functions. A serial communication master is connected via communication links to at least one of the circuit boards so that the at least one circuit board receives messages sent by the communication board, transmits safety oriented messages from and/or to the processing unit of the communication board via one of the secure processing units.

Abstract: The disclosure relates to a subassembly for an expandable automation device, which includes a housing which accommodates a central processing unit, a voltage supply, an interface for connecting external input and output modules, and internal input and output modules. The subassembly can include three electronic subassemblies which are each arranged on a separate carrier, a third carrier being arranged between a first carrier and a second carrier. The first carrier can be configured to accommodate the electronic subassembly of the central processing unit, the second carrier can be configured to accommodate the electronic subassembly of the internal input and output modules, and the third carrier can be configured to accommodate the electronic subassembly of the voltage supply and the interface for connecting external input and output modules.
