A method for operating a web server implemented on a computer, wherein in a launch phase, a web server process ignores requests from clients and a further process having elevated permissions of the web server process is started by the web server process, where the further process serves to execute actions with access to a predefined operating system area, following the launch phase, the web server process transitions to normal operation such that when the web server process then receives a request requiring an action with access to the predefined operating system area, the permissibility of the received request is checked by the web server process and in the event of a permissible request, the web server process and the further process communicate, which prompts the further process to execute the action with the required access to the predefined operating system area.

A system and a method for graphical interconnection of hardware signals of a device, (e.g., a controller device) are provided. The graphical interconnection can now be implemented in a simple manner so that a user can perform this function intuitively and without knowledge of the address convention used in the engineering system. This may be achieved by the inventive system and by the inventive method by the hardware signals being interconnected graphically with program elements of a programming environment using drag & drop features in a graphical user interface.
