Problems solved by technology

[0003] The factory internal network is an important part of the industrial Internet. Due to the complex industrial site environment, there are many kinds of heterogeneous industrial Ethernets in an industrial network system. Profinet and Modbus are typical industrial Ethernets. It is difficult to directly realize cross-network networking and communication, which restricts the development and application of industrial network technology

Abstract

The invention relates to a Profinet and Modbus equipment heterogeneous networking method based on an SDN, and belongs to the technical field of industrial networks. According to the method, an SDN (Software Defined Network) is applied to Profinet and Modbus heterogeneous industrial Ethernet networking; under the condition of unified identification flow based on Profinet and Modbus, networking topology establishment of heterogeneous industrial Ethernet Profinet and Modbus, equipment network access, cross-network communication application relationship establishment, cross-network communication data exchange completion and other functions are integrated, and networking management of Profinet / Modbus heterogeneous industrial Ethernet equipment is realized. According to the method, the problem of cross-network networking communication between Profinet equipment and Modbus equipment is solved, and the efficiency and flexibility of heterogeneous networking are improved through the SDN controller.

Description

technical field [0001] The invention belongs to the technical field of industrial networks, and relates to a method for heterogeneous networking of Profinet and Modbus devices based on SDN. Background technique [0002] In recent years, the Industrial Internet, as a product of the deep integration of a new generation of information technology and industrial systems, has received widespread attention. Industrial interconnection is based on the network interconnection among field devices, control systems, and user products to realize business requirements such as in-depth perception, real-time transmission, and intelligent control of industrial data. [0003] The factory internal network is an important part of the industrial Internet. Due to the complex industrial site environment, there are many kinds of heterogeneous industrial Ethernets in an industrial network system. Profinet and Modbus are typical industrial Ethernets. It is difficult to directly realize cross-network ...
