Example Embodiment

[0038] Example 1

[0039] The overall structure of the method for sharing an industrial Ethernet field bus by an Ethernet device provided by this embodiment is referred to image 3 , The data frame in the industrial Ethernet field bus enters the access device from the industrial Ethernet field bus interface 1, and the access device forwards the industrial Ethernet field bus data frame to the industrial Ethernet field bus interface 2, while passing the Ethernet data The frame type data segment distinguishes standard Ethernet data frames, and forwards the standard Ethernet data frames to the standard Ethernet interface for output. At the same time, it detects the input signal of the industrial Ethernet fieldbus interface 1, and judges whether there is data inflow through the frame synchronization and frame delimitation of the data frame. When detecting that the industrial Ethernet fieldbus interface 1 is idle and no data enters, forward the standard Ethernet interface Upload the bu...

Abstract

The invention discloses a method for transmitting standard Ethernet data in an industrial Ethernet, comprising the following steps of: connecting a standard Ethernet device to a field bus through an access device; orderly transmitting a first standard Ethernet data and an Ethernet field bus data to the access device by a host; distinguishing the Ethernet field bus data and the first standard Ethernet data through a data frame protocol type, and transmitting the first standard Ethernet data to the standard Ethernet device by the access device; meanwhile, transmitting a second standard Ethernet data, fed back by the standard Ethernet device, and the Ethernet field bus data to the host, thereby realizing transmission of the standard Ethernet data between the host and the standard Ethernet device. With the method provided by the invention, transmission of a standard Ethernet data frame in an industrial Ethernet field bus is realized, and wiring mode of industrial field is simplified.

Description

technical field [0001] The invention belongs to the field of industrial Ethernet communication, and more specifically relates to a method for transmitting standard Ethernet data in the industrial Ethernet. Background technique [0002] Industrial Ethernet is a powerful area and unit network based on IEEE802.3. Both industrial Ethernet and standard Ethernet conform to the OSI model, but for the requirements of real-time and high reliability of industrial control, industrial Ethernet adds different functional modules in the link layer and network layer, and adds electromagnetic compatibility in the physical layer. The design solves technical problems such as real-time communication, network security, and anti-strong electromagnetic interference. [0003] In industrial Ethernet fieldbus systems such as EtherCAT and NCUC, it is sometimes necessary to connect standard Ethernet devices such as industrial cameras to the host, and standard Ethernet devices mainly provide Gigabit Et...
