Problems solved by technology

[0009] Third, the conventional fault detection method of fault detection needs to establish a mathematical model, and the complexity and accuracy of the mathematical model are difficult to meet the real-time requirements of high-speed networks; the simplified mathematical model leads to unsatisfactory actual control effects
[0010] Fourth, fault representation Due to the diversity and continuous update of network applications, it is not yet possible to find a clear function that can represent all application layer faults

Embodiment Construction

[0046] like figure 1 figure 2 and image 3 Shown, the present invention comprises the following steps:

[0047] A: Get device site information in Industrial Ethernet

[0048] Based on the TCP / IP protocol family of the industrial Ethernet server, obtain all the device site information existing in the industrial Ethernet, including the device's IP address, MAC address, broadcast frame number, communication frame number, and operating system;

[0049] A1: Assume that there is a local machine in the global system, and the two global variables of this machine are respectively: IPAdd represents the local IP address, and MACAdd represents the MAC address of the local machine;

[0050] A2: First conduct active detection;

[0051] The machine periodically sends an ARP spoofing packet to every possible host in the LAN to obtain the IP address and MAC address of the receiving host;

[0052] A3: Traverse the IP address of each host according to the response reply of the ARP spoofing...

Abstract

The invention discloses an industrial Ethernet network topology management implementation method based on PROFINET. Through Ethernet network topology management, detection of various equipment information in industrial Ethernet such as information of various network servers, routers, printers, switches and the like and network connection relations among equipment is mainly implemented, and a user knows equipment owned by a certain network in the form of a graph and detects whether various equipment can work normally or not. Equipment site information and equipment such as routers and switches are detected in order to detect whether various equipment can work normally or not.

Description

technical field [0001] The invention relates to the technical field of industrial Ethernet control systems, in particular to a PROFINET-based implementation method for industrial Ethernet network topology management. Background technique [0002] PROFINET, launched by PROFIBUS International (PI), is a new generation of automation bus standard based on industrial Ethernet technology. As a strategic technological innovation, PROFINET provides a complete network solution for the field of automation communication, covering hot topics in the field of automation such as real-time Ethernet, motion control, distributed automation, fail-safe and network security, etc. And, as a cross-supplier technology, it can be fully compatible with industrial Ethernet and existing fieldbus (such as PROFIBUS) technology to protect existing investment. [0003] Over the past few years, industrial machine networks have experienced explosive growth in size. The application of the network has penetr...
