Title:

PROFINET PROTOCOL-BASED ACCESS METHOD IN INDUSTRIAL SDN

Document Type and Number:

WIPO Patent Application WO/2021/120285

Kind Code:

A1

Abstract:

The present invention designs a PROFINET protocol-based access method in an industrial SDN, comprising a message processing process of a PROFINET industrial Ethernet protocol in an industrial software-defined network switch, a message processing process of the PROFINET industrial Ethernet protocol in an industrial software-defined network controller, and an access processing process of a PROFINET industrial Ethernet device. Under an industrial software-defined network architecture, the present invention provides a network communication basis for operation of a PROFINET industrial Ethernet device in an industrial software-defined network concerning the problem of difficulty in identification, analysis and processing of a PROFINET industrial Ethernet protocol under an industrial control network architecture and the problem of difficulty in accessing and establishing a communication relationship and the like by the PROFINET industrial Ethernet device.
