Problems solved by technology

In this case, however, the application's access to the automation network must be blocked in order to prevent unwanted direct connections between the public network and the private network, i.e. between the cloud and the automation network
[0010] However, taken together, these measures make it difficult to achieve data security in applications that communicate with both the cloud and the automation network

Embodiment Construction

[0023]figure 1On the upper, ie the virtual line is shown above the public area having the data cloud (Cloud) Cloud CL. A private domain is shown below the dotted separation line, which is an industrial automation device, exemplarily shows a programmable logic controller (PLC) as a member. An edge-device ED having communication interfaces Ka1, Ka2 is shown at the boundary between the two regions. Here, the communication interface KA1 is a proprietary port for an automation network (e.g., a PROFINET), and an exemplar-shown programmable logic controller (PLC) is connected to the port. Communication interface ka2 with public networks, ie Internet connections, and communication with cloud servers (not shown) in the data cloud CL. Although only two communication interfaces KA1, KA2 are shown in this simplified example, but in the real edge device ED, any type of communication interface can be run, which can be operated according to the method proposed here.

Abstract

A method and edge device for controlling data exchange of an industrial edge device with an industrial automation arrangement and a data cloud, wherein the edge device includes a first communication connection to the industrial automation arrangement and a second communication connection to a network of the data cloud, where the edge device includes applications exchanging data, and where the edge device includes a control device to control the data to be exchanged, wherein whether data exchange of an application is controlled via the first communication connection and the data exchange is implemented directly via the second communication connection or vice versa is defined for each application, where a data flow control device ensures simultaneous direct data exchange by an application via both communication connections does not occur, such that rigorous checking of applications or containers within the applications with respect to data security is not required.

Description

Technical field[0001]The present invention relates to a method for monitoring industrial edge devices and industrial automation devices, and data exchange with data clouds, further involves an industrial edge device having data for monitoring edge devices and industrial automation devices and data clouds. Exchange device.Background technique[0002]Industrial automation devices, such as production equipment or process technology devices for discrete goods, typically consist of components controlled by a large number of computer, such as Programmable Logic Controller, and other devices, such as HMI (Man Up) devices. Wait. For various reasons, those connected to each other have traditionally been separated from public networks, especially the Internet, for example, to avoid attacks of production device data.[0003]However, more and more demand is that the active components operated by the industrial automation device in the data of the "island operation" mode can be exchanged with the pu...
