Abstract: 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.

Abstract: A method for detecting a service prevention attack on a first communication terminal, wherein the detection of the service prevention attack is performed by the first communication terminal. The first and at least one second communication terminal comprise communication subscribers in a communication network. The communication connection is provided between the first and the second communication terminals. If the first communication terminal does not receive a status inquiry message of the second communication terminal in a timely manner, receipt of at least one further message indicating that the sender is the second communication terminal is interpreted as a service prevention attack on the first communication terminal and an action is taken, such as all or a plurality of packets are deleted from the input buffer memory or the connection between the two communication terminals is terminated.

Abstract: 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.

Abstract: A distributed control system having system components (1, 2, 3). The positions of the system components (1, 2, 3) are stored in respective memories (11, 12, 13) as component-specific data, which represent the spatial coordinates of the positions. The system components (1, 2, 3) transmit their respective positions to a configuration unit (4) via a communications channel (5). 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 (1, 2, 3) is assigned to the configured system components. In addition, a respective physical address is assigned to each of the system components (1, 2, 3). This achieves simple and reliable configuration of the system components (1, 2, 3). The distributed control system is used, in particular, in process apparatuses.

Abstract: A method for operating a data transmission system with a plurality of stations connected over a common bus, only one of which has access rights to the bus at a given time and controls the data transmission over the bus with call messages addressed to several stations simultaneously. The response times of the called stations are determined. The called stations are parameterized so that they acknowledge and respond to the call message with response messages in the order of their response times. The method is used in field buses in automation technology.

Abstract: A process and a device for addressing stations in a network consisting of at least two segments (S1, S2, S3), wherein network junctions (N1, N2) are provided between the individual segments, which network junctions forward a message from a first segment (S1) to other connected segments (S2, S3) on the basis of path information contained in messages for addressing. The path information of a message to be forwarded through a network junction (N1) contains the station address, valid in the first segment (S1), of the network junction (N1) and an address extension containing a station link identifier for the network junction (N1), and with the help of said address extension the network junction (N1) inserts path information, valid in the other segment (S2), in the message for addressing the receiving station (E2, E3) and forwards it to the other segment (S2). The path information for each station link that can be established via a network junction are advantageously stored in a transmission table.
