Publication number: 20160073443Abstract: A method and apparatus for energy-optimized data transmission by OPC UA protocol in radio networks is disclosed. When OPC UA communication is operated in a mobile device, e.g. as mobile access to part of a plant for maintenance, monitoring, parameterization, transmission is frequently implemented by the OPC UA's own request-response based communication behavior. Since the device is rarely able to switch off the transmitter, the battery of the device is very quickly discharged. This poses a problem, particularly in the case of devices that are intended to respond promptly to infrequent warnings or events. However, when a client device is intended to provide notification in relation to one event only, the previous polling, i.e. the periodic interrogation is dispensed with and an alternative notification through means inherent in the mobile network is used. This method uses, for example, a mobile push service supplied by the network provider.Type: ApplicationFiled: September 9, 2015Publication date: March 10, 2016Applicant: SIEMENS AKTIENGESELLSCHAFTInventors: KARL-HEINZ DEIRETSBACHER, CHRISTIAN HOCK, GERALD KAEFER, FRANK VOLKMANN

Publication number: 20150189003Abstract: A method for optimizing repeated write access by a client to at least one variable in a server via OPC UA, wherein a call method for repeated write access is provided on the server, the call method includes notification of an access time interval and at least one variable for the repeated write access, the client calls the call method on the server, the server is notified of an access time interval and the at least one variable for the repeated write access in the process, where the server creates a data structure for the repeated write access and maintains said data structure during the access time interval, values of the at least one variable which are to be written are transmitted to the server by the client during the access time interval, and the server allocates each value transmitted by the client to the associated variable.Type: ApplicationFiled: July 24, 2012Publication date: July 2, 2015Applicant: Siemens AktiengesellschaftInventors: Markus Erlmann, Christian Hock, Frank Volkmann

Publication number: 20150156252Abstract: A method for providing clients with access to a service of a server in a network using an OPC-UA, the server service making available varying values of at least one variable to the clients, wherein a client registers for the server service by sending a subscription request for the server service to the server which sets up a subscription structure including a unique subscription ID as well as a TCP/IP multicast group associated with the subscription structure and including a unique multicast address, and there server communicates the multicast address and the subscription ID to every client submitting a subscription request to register for the server service, the server additionally sends each change in value of each variable of the server service to the multicast address over a network via a multicast message so that all clients registered for the server service receive the same multicast message.Type: ApplicationFiled: May 31, 2012Publication date: June 4, 2015Applicant: Siemens AktiengesellschaftInventors: Frank Volkmann, Markus Erlmann, Christian Hock

Publication number: 20150142873Abstract: A method for communication between two clients via a server in a network using OPC Unified Architecture (OPC-UA), wherein a virtual server object that provides a server functionality to a first of two clients is implemented in the server by making available to the first client a virtual address space in an address space of the server, and a process for generating and modifying virtual server nodes in said virtual address space. The server allows the second client to access virtual server nodes in the virtual address space and informs the first client each time that the second client accesses a virtual server node in the virtual address space.Type: ApplicationFiled: May 31, 2012Publication date: May 21, 2015Applicant: Siemens AktiengesellschaftInventors: Frank Volkmann, Markus Erlmann, Christian Hock

Publication number: 20130144408Abstract: A method for controlling an electric machine or electric unit by actuating a component of the electric machine or unit using a predicate and by automatically examining the component in regard to the performance of the predicate to permit examination of an automated system for possible errors in a simply manner, wherein the predicate contains an expected value of a (physical) quantity of the component, and wherein in the examination of the component, a check is performed to determine whether the expected value actually arises when the predicate is performed such that erroneous situations can be detected by a runtime system without explicit programming being necessary therefor.Type: ApplicationFiled: June 24, 2010Publication date: June 6, 2013Applicant: SIEMENS AKTIENGESELLSCHAFTInventors: Thomas Edelmann, Stefan Elsterer, Christian Hock, Jörn Peschke, Frank Volkmann

Patent number: 8078672Abstract: In one aspect, method for bidirectional asynchronous data communication between a client and a server over the Internet via a hypertext transfer protocol based on a request/response paradigm is provided. With the aid of a single communication channel, a communication sequence is initiated by the client, such that the two partners are able to exchange data asynchronously and bidirectionally. After the client has established the connection via a request the client sends data to the server as a further request, while the server sends data to the client as a response to the last request. If the server has no data to send, then after a timeout time it sends a dummy response in order to keep the channel open. If the server receives a new request, then it terminates the old one and sends any data remaining to be sent as a response to the new request.Type: GrantFiled: September 21, 2006Date of Patent: December 13, 2011Assignee: Siemens AktiengesellschaftInventors: Karl-Heinz Deiretsbacher, Christian Hock, Frank Volkmann
