Embodiment Construction

[0052] figure 1 A very simplified purely schematic illustration of an embodiment of the automation system 1 according to the invention is shown.

[0053] The automation system includes a plurality of components, and also a plurality of field devices and programmable logic controllers, at least several of which are supplied via IO devices. Two IO devices 2 and a programmable logic controller 3 are shown by way of example in the figures from several components. "..." between two IO devices 2 means that of course there can be or more IO devices 2. The controller 3 and the IO device 2 are used as known sufficiently in advance from the prior art in order to monitor and control technical processes not further shown. It can obviously be implemented in a way also known in advance, also providing more than one controller 3 and / or also other components, eg HMI panels and / or the like.

[0054] The components of the automation system 1 are interconnected via a network 4 for data excha...

Abstract

The invention relates to a method for configuring at least one OPC UA publish-subscribe user (2, 3) in a network (4), in particular an industrial network, in which a) a virtual address space (9) is provided for the at least one user (2, 3) on a configuration module (6) separate from the at least one user (2, 3), b) in the virtual address space (9) of the at least one user (2, 3), the configuration module (6) is used for configuring the at least one user (2, 3) for the at least one OPC UA publish-subscribe user (2, 3). The configuration and / or change of the configuration of the at least one user (2, 3) for the already existing configuration of the at least one user (2, 3), c) the configuration module (6) converts the configuration and / or the configuration change into at least one publish-subscribe message, d) the at least one publish-subscribe message is transmitted to the at least one user (2, 3), and e) the at least one user (2, 3) is configured in accordance with the at least one publish-subscribe message. Furthermore, the invention discloses an automation system (1), a computer program and a computer readable medium.

Description

technical field [0001] The present invention relates to a method for configuring at least one OPC UA publish-subscribe user in a network, in particular an industrial network. Furthermore, the present invention relates to an automation system, a computer program and a computer-readable medium. Background technique [0002] OPC UA (OPC Unified Architecture) is an industry standard protocol of the OPC Foundation for manufacturing-independent communication for the exchange of machine data, especially in process and manufacturing automation. [0003] by the OPC Foundation ( https: / / opcfoundation.org / ) discloses a multi-segment specification for the OPC Unified Architecture ( https: / / opcfoundation.org / developer-tools / specifications-unified- architecture / ). [0004] OPC UA is also published in the book "Industry 4.0 - Industrial Communication - Fundamental Technologies for Industrial Digitalization" by the DIN Standardization Association, Markus 2017, VDE Press, Chapter 4...
