摘要： In automation-engineering installations, there is a need to exchange process information between different devices. For this, OPC Unified Architecture (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： The invention describes a transmission device having a (TCP/IP) protocol stack (S, S′), which is designed for the transmission of data (D) in a time-sensitive network (TSN). The transmission device comprises at least one TSN-compliant virtual Ethernet interface (2.2, 2.2′) and an associated TSN control unit (3.1, 3.1′). The at least one TSN-compliant virtual Ethernet interface (2.2, 2.2) is designed to send and/or receive a TSN-compliant data stream (2.1, 2.1) in a physical layer (1) of the TCP/IP protocol stack (S, S). The TSN-compliant data stream (2.1, 2.1′) can be configured and/or parameterised by means of the associated TSN control unit (3.1, 3.1′).

In addition, the invention relates to an automation system, a computer program and a computer-readable medium.

摘要： A method is provided which enables industrial communication via the TSN protocol by means of sockets. Owing to the described method, the possibility of communicating with the socket programming known to the programmer via TSN streams is provided. As a result, simple use of the new TSN quality for simple Internet (IP) programming is possible. Existing applications can easily be expanded for TSN and can therefore benefit from the robustness of TSN in a simple manner. In addition, parallel operation is possible; the same mechanism is always used.

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： The present invention relates to a method, a computer program product and a system for providing services, in particular in an industrial automation system. Users of control applications implemented for industrial automation systems by way of container virtualization expect the integration of such applications into their existing infrastructure to be as straightforward as possible. Depending on the network connection and the flow control environment used, in particular OPC UA servers encounter different configurations that need to be taken into consideration by developers of control applications for automated configuration methods for the control applications. For this purpose, a smart proxy for OPC UA servers in virtual machines or Docker environments, such as in Industrial Edge, is used and intervenes in the initially still unsecure service communication in order to ensure that OPC UA clients can successfully connect to OPC UA servers in a container host/Industrial Edge.

摘要： The invention relates to a method for configuring an industrial real-time-capable communications network for the cyclical transmitting of messages (NWM), each comprising one or more data sets (DS1, . . . , DS4). The communications network (1) comprises a message source (10) for generating and cyclically sending the messages (NWM), at least one message sink (16, 17, 18) for receiving and processing the messages (NWM), as well as at least one network component (12, 14) which forwards messages (NWM) from the message source to the message sinks. The configuring comprises determining (S1) a network topology of the communications network (1) for the transmitting of a data stream to be sent from the message source (10) in the future, in which the messages (NWM) are each cyclically sent with all data sets. It is determined (S2) which of the data sets in the data stream a respective one of the message sinks wants to receive. In addition, a respective filter (12F, 14F) is determined (S3) and designed (S4) for each network component, whereby, from the network topology, the components connected to the respective network components and the data sets required for the connected message sinks are determined. In this way, during operation of the communications network (1), exclusively required data sets are transmitted in the messages (NWM) in a downstream direction of the data stream.

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.
