EtherNetIP协议及其通信适配器的实现
The realization of communication adapter with the protocol of EtherNet/IP
Abstract
工业以太网协议(EtherNet/IP)是由ODVA所开发并得到了罗克韦尔自动化的强大支持。它使用已用于ControlNet和DeviceNet的控制和信息协议(CIP)为应用层协议。EtherNet/IP通信处理器是一种基于工业以太网协议，满足工业现场数据网络化要求的通信设备。这种通信处理器支持TCP/IP等标准Internet协议，满足了高精度时间同步、分布式伺服控制、离散控制等工业应用要求，完成现场和远程系统监视、诊断和组态功能，因此EtherNet/IP通信处理器对通信的实时性、可靠性有非常苛刻的要求。传统8/16位单片机存在明显不足，加之无法支持嵌入式操作系统，从而无法满足多任务信息... EtherNet/IP is developed by the ODVA and received strong support from Rockwell Automation. It uses the control and information protocol (CIP) for the application layer protocol that has been using for ControlNet and DeviceNet. EtherNet/IP communication processor is a kind of network equipments that bases on EtherNet/IP and meet the requirements of industrial data communications. Such communication...
