A method for operating an automation system having a CPU unit that is provided for processing a control program for controlling a technical process, wherein a power supply module of the automation system supplies electric energy to units that consume electric energy. During the control of the process, the energy consumption is optimized, such that the necessary automation functions for controlling the technical process are maintained.

Method for operating a modular automation device

The invention relates to a method for data transmission, comprising the following steps: first data from a stochastic process is inputted into at least a first and a second subscriber of a communication network; and a symmetrical key is produced on the basis of the first data in both the first and the second subscriber, and stored in the same, for an encoded data transmission between said subscribers.

Method for encoded data transmission via a communication network

A distributed control system having system components (). The positions of the system components () are stored in respective memories () as component-specific data, which represent the spatial coordinates of the positions. The system components () transmit their respective positions to a configuration unit () via a communications channel (). By means of a layout plan, e.g., in the form of a piping and installation diagram, the component-specific data of the individual system components () is assigned to the configured system components. In addition, a respective physical address is assigned to each of the system components (). This achieves simple and reliable configuration of the system components (). The distributed control system is used, in particular, in process apparatuses.
