摘要： An OPC UA session is interpreted as a single transaction according to the invention. In this case, a transaction means that all service calls, apart from the above-mentioned calls, are initially only simulated and are not executed and the execution of the service calls is shifted to the termination of the transaction. Each operation inside a session is formally checked and then simulated. The simulated result or the result of the formal check is immediately sent to the client. The client therefore receives a preview of the result of the operations. If the client determines that one of the operations carried out would not lead to the desired result, the client can reject the operations. If the client wants the set operation to be carried out, the client terminates the current session.

摘要： In the OPC UA request header, there exists the field “TimeoutHint”, by means of which the client can indicate the point in time from which the client is no longer interested in the result of an operation. When this time has expired, the server sends a response that the execution of the operation has been terminated. According to the invention, the semantics of the field “TimeoutHint” in the OPC UA request header are used differently. The meaning of the “TimeoutHint” is changed in such a way that the “TimeoutHint” no longer indicates the latest point in time at which an operation should be executed, but rather the earliest point in time.

摘要： In automation-engineering installations, there is a need to exchange process information between different devices. For this, OPC Unified Automation (OPC UA) from OPC Foundation has become established as a standard protocol. However, rather than transmit requested OPC-UA subscriptions via the conventional OPC-UA session channel, the invention sets up a separate TSN data communication by means of which that subscription information is transmitted.

摘要： A method for diagnosing transmission interference in a data network, where the data network includes first network elements which transmit and/or receive first data packets according to a data transmission standard for implementing real-time communication, and second network elements which do not or do not only transmit and/or receive second data packets according to said data transmission standard. Diagnostic data packets are introduced into the data network. A path of the diagnostic data packets through the data network is determined. The data network is flooded with the diagnostic data packets. The diagnostic data packet is transmitted from the first network element to the second network element. Whether second network element receives the diagnostic data packet is determined. When there is interference, all network element ports through which the diagnostic data packet passes are determined. A mark that indicates potential transmission interference is applied to the determined network element ports.

摘要： A method for operating a server device in a system is disclosed. The server device determines a current process value of at least one process parameter of a process controlled by the system and transmits the determined current process values to a plurality of client devices in the system for each process parameter or a subset thereof via a data network. According to the invention, the server device forms a variable group for at least one process parameter which is to be transmitted to more than one of the client devices. The server device then combines in each case the current process values of the at least one process parameter in the variable group at the different transmission times to form a single multi-target message and at the different transmission times to form a single multi-target message and transmits the multi-target message to a group address in the data network.

摘要： An OPC UA client that consolidates transmission and reception times so as to extend the antenna amplifier pause times is disclosed. Thus, without requiring a change to the OPC UA protocol, data is sent exclusively at defined focusing times. No sending is meant to be necessary between these times. A set of requests is sent to the server at a particular time. The client then enters reception mode. The server handles the received requests periodically over time. When almost all requests have been handled, a new set of requests is made to the server again. Between these focusing times, the transmitter of the client/mobile device can be switched off completely and hence save power. The method disclosed is totally compatible at all levels of communication, both TCP stack, WLAN for instance.

摘要： 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.
摘要翻译：公开了一种在无线网络中通过OPC UA协议进行能量优化数据传输的方法和装置。当OPC UA通信在移动设备中操作时，例如，由于OPC UA自己的基于请求响应的通信行为，通常会实现对维护，监控，参数化，传输的一部分的移动访问。由于设备很少能够关闭变送器，所以设备的电池很快放电。这就造成了一个问题，特别是在意图对不常见的警告或事件进行快速响应的设备的情况下。然而，当客户机设备仅旨在提供关于一个事件的通知时，先前的轮询，即周期性询问被省略，并且使用通过移动网络固有的手段的备选通知。该方法使用例如由网络提供商提供的移动推送服务。
