Patent number: 11652661Abstract: The claimed interface extension device is based on a network device (DCC) having at least one previously unoccupied digital data output (OUT), to which an interface extension module (IOE) having at least one supply voltage input (S) and having a plurality of digital interfaces is coupled in the claimed manner. In this way, the supply voltage input (S) of the interface extension module (IOE) is interconnected with the digital data output (OUT) of the network device (DCC), so that in event of an error, the interface extension module (IOE) and all the digital interfaces thereof can be switched off. In addition, by measuring the sum current flowing through the outputs of the interface extension module, the load diagnosis capacity of the network configuration can be extended to the interface extension device.Type: GrantFiled: May 19, 2016Date of Patent: May 16, 2023Assignee: Siemens AktiengesellschaftInventors: Michael Armbruster, Andreas Zirkler

Patent number: 11108590Abstract: A network mechanism for a communication network, e.g., Ethernet environment, includes a first control mechanism with an assigned first physical port and a second control mechanism with an assigned second physical port, the first and the second physical port being configured to receive and send data via a transmission medium. The network mechanism is configured such that transmitted data from the first control mechanism are coupled by an internal transmit connector of the first control mechanism via the first physical port into the transmission medium and received data at the second physical port are routed to an internal receive connector of the first control mechanism. Alternatively, received data can be routed crosswise to the other control mechanism, i.e., the control mechanism not assigned to the receiving physical port. The crosswise routing enables the formation of two independent ring-shaped communication paths of different transmit/receive directions within a single physical ring-shaped network.Type: GrantFiled: May 30, 2013Date of Patent: August 31, 2021Assignee: SIEMENS AKTIENGESELLSCHAFTInventors: Michael Armbruster, Ludger Fiege, Johannes Riedl, Thomas Schmid, Andreas Zirkler

Patent number: 10491317Abstract: A method for operating a network arrangement having a plurality of network systems is disclosed. Data belonging to a first class is synchronously transmitted in a specified time slot identical for all network systems. A network system, which owing to a synchronization error during the specified time slot, receives data belonging to other classes from a plurality of senders, then only sends data belonging to the first class, but now in standard messages belonging to class 2. Non-vital data belonging to the other classes is no longer transmitted in this operating state. Improved failure safety and in particular a fail-operational mode is provided by the behavior of the network systems in the event of synchronization errors. A network system which implements the method and a network arrangement having a plurality of corresponding network systems is also proposed.Type: GrantFiled: June 17, 2013Date of Patent: November 26, 2019Assignee: SIEMENS AKTIENGESELLSCHAFTInventors: Michael Armbruster, Ludger Fiege, Johannes Riedl, Thomas Schmid, Andreas Zirkler

Patent number: 10454848Abstract: The invention relates to a method for operating a communication network (101), in particular an Ethernet network. Network devices (1) which are coupled to the network comprise a switch device (4), a first and a second control device (2, 3) which are coupled to the switch device (4), and the switch device (4) comprises for the first and the second control device (2, 3) a respective input port (10, 14) and emitter port (9, 13) for sending and receiving data via the communication network (6). Ring-shaped communication paths for data are provided so that redundant data can be transmitted in different directions and checked for consistency. An improved protection against failure and error analysis in the event of transmission errors are ensured by the ring-shaped structure using bidirectional communication paths. The invention further relates to a network arrangement (101) comprising several corresponding network devices (100, 200, 300) which operate according to the method.Type: GrantFiled: September 3, 2012Date of Patent: October 22, 2019Assignee: Siemens AktiengesellschaftInventors: Michael Armbruster, Ludger Fiege, Johannes Riedl, Thomas Schmid, Andreas Zirkler

Publication number: 20180322001Abstract: The disclosure relates to at least two processor cores of a multicore processor for dual-lane computing of a security-critical application. The two processor cores are used to full capacity in different working cycles for computing operations of different applications, rather than computing operations being redundantly carried out by both processor cores in each computing cycle. This advantageously avoids duplication of the computational capacity required. For the processor cores to monitor each other, the computing operations are alternatingly carried out by the two processor cores. Any errors may be avoided by the error detection mechanisms described. Although the quality of the error detection is somewhat lower than the “dual-lane operation” known from the prior art with parallel, redundant multi-lane calculations, the quality of the error detection may satisfy the requirement of lower computational outlay, (e.g., when an economic implementation of the control system is required).Type: ApplicationFiled: October 21, 2016Publication date: November 8, 2018Inventors: Michael Armbruster, Christian Buckl, Ludger Fiege, Andreas Zirkler, Martin Bischoff

Patent number: 10082822Abstract: One or a plurality of sub-networks are defined in the communications network. Each of the sub-networks includes a plurality of network nodes from the communications network. One or a plurality of the sub-networks represent pre-determined sub-networks, in which respective pre-determined network nodes have both the function of a global slave node and the function of a local master node. The one or the other network nodes of the respective pre-determined sub-networks are local slave nodes. In addition to global synchronization using the global master node and the global slave nodes, local synchronization is also performed in the pre-determined sub-networks using the local master node and the local slave nodes. Thus, in the event of an error outside a pre-determined sub-network, the local synchronization may be continued, whereas the global synchronization is aborted. It is thus avoided that an erroneous synchronization is propagated into corresponding sub-networks.Type: GrantFiled: May 23, 2014Date of Patent: September 25, 2018Assignee: Siemens AktiengesellschaftInventors: Michael Armbruster, Michael Bernhard Buhl, Dragan Obradovic

Patent number: 9998385Abstract: A method for operating a communications network, in particular an Ethernet network is provided. Network devices that are coupled to the network have a switch device and a control device that is coupled to the switch device, and the switch device has at least one receiving port and a sending port for sending and receiving data via the communications network. Fuse devices for monitoring a particular data transfer rate are assigned to the receiving ports. The fuse devices block data reception at a particular receiving port when a previously determined maximum data transfer rate is exceeded.
