Hardware Design Of Ethernet/IP Adapter

The industry Ethernet is the focus of industrial research in recent years. Compared to our outdated technology in Fieldbus field, we should strengthen the research in this field. This dissertation elaborates the development of Ethernet/IP communication processor, which is industrial control local instrument conforming the industry Ethernet Ethernet/IP agreement, which cooperate with Shanghai Hurco Industrial automation Company. The application of the industry Ethernet Ethernet/IP mainly includes two aspects: (1) On the traditional integrated industrial equipment, as communication bridge between the level of information management in the industrial control system to the level of local instrument.(2)As the independent equipment, it is the Internet network's foundation equipment of Ethernet/IP industry, in this situation, the different agreement's industrial equipment and the industrial control system realize the data integration, the protocol conversion through connecting to the Internet communication controller of the Ethernet/IP industry.The dissertation introduces the development survey and core technique of Industry Ethernet Network, and simply describes some of the existing typical International Industry Ethernet Protocols, including Modbus-IDA Industry Ethernet, Ethernet/IP Industry Ethernet, ProfiNet Industry Ethernet, FF HSE Industry Ethernet. The dissertation also elaborates on Ethernet Technique about Ethernet/IP, including protocol model and application layer protocol CIP of Ethernet/IP.As the mediation point of Control System, Ethernet/IP Communications Processor has high requirements on real-time performance and reliability so that it has to establish a stable and sturdy hardware platform as foundation of Communication Processor. Hereby, this article designs a hardware system based on the core of S3C2410A Microprocessor. The hardware system makes best of the excellent Kernel performance and abundant peripheral equipment interface and constructs the hardware platform with Ethernet,USB,RS232,LCD and I/O expand interface. This article illuminates the design work of principle drawing and PCB and so on, and also do the substrate test to the final hardware system in virtue of instruments. The test result shows that Ethernet/IP Communications Processor has excellent stability, reliability and real-time performance.In the end, the dissertation gives the summary of the research and the points which need further improvement.
