Abstract

The invention provides a protocol conversion device, which comprises: a first network slave station protocol stack for receiving a control instruction for electronic equipment sent by a first networkprotocol chip and generating an object dictionary instruction set; a second network master station protocol stack which packages the object dictionary instruction set into a second network data frame,wherein the second network data frame is in a second network protocol format; according to a preset communication period, the second network frame is stored in a second network protocol chip, the state and position information of the electronic equipment is read from the second network protocol chip, and the communication period is a period for communicating with the second network protocol chip;the state and position information of the electronic equipment is packaged into the first network data frame, and the first network data frame is stored in the first network protocol chip, so that the mutual use of industrial equipment supporting two protocols is realized, and the application range of the industrial equipment is expanded. The invention further provides protocol conversion equipment and a protocol conversion method adopting the protocol conversion device.

Description

【Technical Field】

[0001] This application relates to the field of communication technology, and in particular to a protocol conversion device, protocol conversion equipment and method. 【Background technique】

[0002] In the field of industrial control, the interconnection between various industrial control equipment has become more and more important, and the communication has also developed from the earliest fieldbus to the current industrial Ethernet.

[0003] EtheCAT (Ether Control Automation Technology, Ethernet control automation technology) is currently a very widely used industrial Ethernet. It is one of the IEC61158 international standards. It has fast transmission speed, high real-time performance, accurate synchronization performance, and can support up to 65535 For each slave station, the minimum interpolation cycle can be 12.5us. The physical layer uses standard 100M Ethernet, the data link layer uses a standard network card chip for the master station, and the slave s...
