Problems solved by technology

[0014] However, this UDP mechanism does not explicitly guarantee quality of service, so it should only be used in environments where data loss is acceptable (at least temporarily)

Embodiment Construction

[0035] The example set forth below is a preferred embodiment of the invention. In this example, however, the described components of the embodiment are features of the invention that are observed independently of each other, and which also improve the invention independently of each other, so that they can also be used individually or in a different manner than the ones described. Combinations of the indicated combinations are considered to be part of the present invention. Furthermore, embodiments can also be supplemented by other features of the invention that have already been described.

[0036]A client requests one or more subscriptions at the server, and a subscription has one or more elements (monitor objects) and characteristics (eg, publication rate).

[0037] exist figure 1 Five servers are exemplarily given in , and they request information as follows:

[0038] Client A

[0039] Objects: z, y

[0040] Proxy Server: Redundant

[0041] Client B

Abstract

In automation-engineering installations, there is the need to exchange process information between different devices. For this, a standard protocol OPC Unified Automation (OPC UA) from OPC Foundationhas become established. The idea is not to transmit requested OPC-UA subscriptions via the conventional OPC-UA session channel, but rather to set up a separate TSN data communication by means of whichthe subscription information is transmitted.

Description

technical field [0001] The invention relates to a plant for controlling a process, such as a manufacturing process, in which a server device determines a current process value for at least one process parameter, such as temperature, at different transmission times and distributes it to a plurality of other device, referred to herein as a client device. Also belonging to the invention are a corresponding server device and a corresponding client device as well as a method for operating the server device. Background technique [0002] In automation technology installations, or installations for short, it is necessary to exchange process information between different devices. The OPC Unified Automation standard protocol (OPC UA) of the OPC Foundation was established for this purpose. (OPC - OLE for Process Control, OLE - Object Linking and Embedding). [0003] It often happens in such scenarios that multiple consumers (clients) of process information are interested in the sam...
