Abstract: A control system controls safety-critical and non-safety-critical processes and/or system components. The system includes a first control unit for controlling the non-safety-critical process and/or the non-safety-critical system components, at least one input/output unit connected to the first control unit, a communication coupler, which is connected to the first control unit via an internal coupler bus, and a second control unit for controlling the safety-critical process and/or the safety-critical system components. For providing safety-related functions, the second control unit includes a first dual-port RAM and at least two processors, only one of which is connected to the first dual-port RAM.

Abstract: A method and device for the programming and configuration of a programmable logic controller are disclosed. The method can include: locating a configuration tool in a programming tool, wherein the configuration tool includes a module in an IEC61131 language; integrating at least one further module into the configuration tool, and executing the programming and configuration of the programmable logic controller in a high-level language using a C-Code editor, and wherein the at least one further module is configured to provide a definition of interfaces between an IEC61131 code and a high-level language code, and provide a configuration of the high-level language code.

Abstract: Exemplary embodiments are directed to a system and method for configuring a control device in an automation system. The system including a hardware structure, and a programming tool connected to the hardware structure and the control device. The programming tool is configured to transmit a control program and configuration files to the control device, and store a control project in memory. The programming tool registers modifications of the hardware devices using software “FlexConf.ini” as modification information and sets the control device to a mode “control with flexible configuration” via a parameter “FlexControl”. The programming tool also determines a type for transmitting the modification information in the parameter “FlexControl”, and transmits the modification software with the modification information stored therein in accordance with the transmission type set in the parameter “FlexControl” to the control device.
