Problems solved by technology

Therefore, there is currently no automated solution to test whether the debugged network is correctly deployed or whether the network contains errors, and therefore, in the case of a wrongly deployed network, errors are only noticeable during testing or operation of industrial automation and control systems, This can cause significant production delays, downtime or even safety risks

Embodiment Construction

[0025] figure 1 A verification unit 10 according to the invention is shown. The verification unit 10 includes a planning module 11 , a collector module 12 , a difference detector 13 and a notification module 14 . Preferably, the verification unit 10 and / or the functional modules contained in the verification unit 10 are implemented as programming software modules including computer program codes for instructing a processor of a computer to perform functions as described below. The computer program code is stored on a tangible computer-readable medium, which is fixedly or detachably connected in the corresponding computer. However, those skilled in the art will appreciate that in alternative embodiments, functional modules may be fully or at least partially implemented by hardware components. The computer may include one or more network interfaces, for example, to receive planning data for the designed communication network of the industrial automation and control system, and...

Abstract

The invention relates to a unit (10) for validating a communication network of an industrial automation and control system. The verification unit (10) includes: a planning module (11) configured to store planning data defining a designed communication network of the industrial automation and control system; and a collector module (12) configured to collect all planning data defining the industrial automation and control system Effective data for deploying communication networks. The verification unit (10) also includes a difference detector (13) configured to detect differences between the designed communication network and the deployed communication network using the planning data and the valid data. Accordingly, faults or errors in deployed communication networks in industrial automation and control systems can be efficiently detected.

Description

technical field [0001] The invention relates to a unit for validating a communication network of an industrial automation and control system, and to a method of validating a communication network of an industrial automation and control system. Background technique [0002] Industrial automation and control systems are used to control industrial facilities used, for example, to manufacture goods, generate electricity, process substances, generate electricity, and the like. Over the past few years, Ethernet has been widely used as a communication technology in industrial automation and control systems. However, the use of Ethernet presents new challenges for debug engineers, especially ensuring that the network is behaving as expected. In the past, when only analog communication techniques were involved, network connections could be easily verified with a multimeter. In current communication technologies, such as Ethernet, when nodes or network controls, such as network swit...
