Implementation method of high-speed fieldbus based on industrial Ethernet

Abstract

The invention provides an implementation method of a high-speed fieldbus based on industrial Ethernet, which comprises the following steps: (1) electrifying a fieldbus system, and carrying out initialization setting; carrying out the step (3) if the initialization setting is successful, otherwise, carrying out fault treatment of the step (2); (2) carrying out the fault treatment; (3) carrying out data communication, and returning to the step (2) for carrying out the fault treatment if a fault emerges; entering into the idle state if the cycle further has remaining time after completing data transmission of all station points, waiting for the next data sending or receiving request, returning to the step (2) for carrying out the fault treatment if the fault emerges during the waiting process, otherwise, carrying out the step (4); and (4) finishing the communication. The invention further provides the high-speed fieldbus system based on the industrial Ethernet for implementing the method, that is a GSK-Link high-speed fieldbus system. Slave stations can mutually carry out the data communication, thereby greatly improving the data transmission speed and the efficiency.

Description

technical field [0001] The invention belongs to the technical field of field bus, in particular to a method for realizing a high-speed field bus based on industrial Ethernet (i.e. a method for realizing a GSK-Link high-speed field bus based on industrial Ethernet) and a high-speed field bus based on industrial Ethernet for realizing the method. Bus system (that is, GSK-Link high-speed field bus system based on industrial Ethernet). Background technique [0002] High-speed field bus refers to the digital, serial, multipoint communication data bus between the field devices installed in the manufacturing or process area and the automatic devices in the control room. It is an all-digital, two-way, The multi-station communication system mainly solves the digital communication between intelligent instruments, controllers, actuators and other field devices in the industrial field, as well as the information transmission between these field control devices and advanced control syste...

AI Technical Summary

Problems solved by technology

[0004] However, in the prior art, the implementation method of the high-speed field bus based on industrial Ethernet is relatively simple, and only the communication between the master station and the slave station can be realized, and it is difficult to realize the communication between the slave station and the slave station, which greatly The transmission speed of its communication data is greatly limited; moreover, the existing technology is usually controlled by a custom circuit, which has relatively large limitations, high cost, and limited number of gate circuits of programmable devices.
