Patent number: 8943188Abstract: The invention relates to an automation network and to automation equipment, network components and field devices for an automation network of this type. The network components transmit messages concerning their status to the automation equipment by means of a communication mechanism that functions according to field communication automation technology. Said automation equipment receives the status messages, evaluates them, monitors the operation of the network and controls said operation using the status messages. As the automation equipment thus contains the complete picture of the process and the network, it can react directly and rapidly to problems of the network. This eliminates the need, for example, for an additional SNMP/OPC server or a network management station.Type: GrantFiled: April 8, 2005Date of Patent: January 27, 2015Assignee: Siemens AktiengesellschaftInventors: Ralph Büsgen, Karl Glas, Michael Kasper, Joachim Koppers, Andreas Köpke

Patent number: 7177708Abstract: A method and a system for the automated control of a technical installation (2) having a plurality of installation components (4) that are interconnected by data transmission in order to carry out process steps. Control commands (S) which are generated by a central control device (6) are fed to these components in accordance with process control signals (P) that are sent to the device. Process control signals (P) that are generated in a mobile operator unit (12) are wirelessly transmitted to interfaces (14) and are forwarded by the latter to the control device (6). The installation components (4) for which the system considers the process control signals (P) received from the mobile operator unit (12) during the generation of the corresponding control commands (S) are released using a local characteristic value (O) for the mobile operator unit (12).Type: GrantFiled: January 31, 2005Date of Patent: February 13, 2007Assignee: Siemens AktiengesellschaftInventors: Karl Glas, Juergen Kroener, Matthias Rebellius, Ulrich Sinn

Publication number: 20030055900Abstract: A network has redundancy features and includes at least two series constructed of a number of network subscribers (100 . . . 107; 110 . . . 117). The at least two series are connected to one another via at least two communication channels, of which only the first one is active and the second one is deactivated. The communication channels are realized by connecting ports of the network subscribers. A network subscriber of the second communication channel monitors the first communication channel for interruption and places the second communication channel into the active state if the first communication channel is interrupted. The network subscribers have several ports, to which further network components can be connected. A microprocessor interface (25) connects the ports (28 . . . 31) with a user-internal processor bus. A switch control (46) provides message route management between the ports (28 . . . 31) and the microprocessor interface (25).Type: ApplicationFiled: August 2, 2002Publication date: March 20, 2003Applicant: SIEMENS AKTIENGESELLSCHAFTInventors: Karl Glas, Dieter Klotz, Christoph Muench

Patent number: 6430151Abstract: An Ethernet network with redundancy properties and an associated method for detecting and eliminating errors in the network. A redundancy manager (6), which is connected to the line ends of the network (1), checks the status of the network by transmitting and receiving test telegrams. If there is an interruption in the network, the redundancy manager (6) connects the line ends (7, 8) and thereby ensures continued network operation within milliseconds. The network has a loop structure that is less expensive than a dual bus structure even though fast media redundancy is ensured.Type: GrantFiled: September 11, 2000Date of Patent: August 6, 2002Assignees: Siemens Aktiengesellschaft, Richard Hirschmann GmbH & Co.Inventors: Karl Glas, Joachim Lohmeyer, Rolf Reuschen, Bernhard Schmid
