The Design And Realization Of The Software Based On EtherNet/IP Communication Adapter

Using "EtherNet/IP Communication Adapter development" commissioned by Shanghai Hurco industrial automatic company as background, this thesis designs and realizes a communication adapter of Industrial Ethernet based on EtherNet/IP, this communication adapter is used as a gateway between EtherNet/IP control network and other technologies, it can integrate industrial control equipments to EtherNet/IP industrial Ethernet, and make the control system more flexible and compatible. Industrial Ethernet technology and embedded technology are the hottest topic of recent application and research. According to the analysis of the evolution concerning about Industrial Ethernet technology and embedded system, a comprehensive scheme for Industrial Ethernet intelligent equipment was presented in this thesis. This design not only satisfies the functional requirements for Ethernet protocol, but also fits the developmental tide of the embedded system progress of adopting 32-bit microprocessor and embedded operating system (OS), and satisfies the rigorous request of the Ethernet/IP communication adapter's real-time and reliable communication.Aimed at the design of the EtherNet/IP communication adapter, this thesis adopts S3C2410 ARM9 microprocessor and Windows CE.NET operating system, and develops the communication processor's Boot Loader program and I/O interface's driver. The Boot Loader program, which is highly relevant to the hardware, initializes hardware platform and boots Windows CE.NET OS. While the I/O interface's driver makes the OS detect peripherals automatically, and provides services for the applications to control the bottom equipments.Furthermore, the thesis also concentrates on the design of the application of this communication adapter based on the EADK (EtherNet/IP Adapter Developers Kit) , and realizes CIP in application layer, which guarantees the effective transmission of the real-time I/O data and explicit message in network. In addition, ElPScan, EDITT, ControlLogix PLC and PCU-ETHIO EtherNet/IP scanner have been used to test this communication adapter completely, and it has been demonstrated that this Ethernet/IP communication adapter has excellent real-time property, stability and reliability in data transmission.
