摘要
DeviceNet总线是一种面向对象的开放的设备级现场总线。DeviceNet在充分利用CAN总线物理层和数据链路层的基础上,提出一种独特的应用层协议,在工业控制领域应用日益广泛。文章首先描述了基于ARM7硬件平台的μC/OS-II系统移植,然后在μC/OS-II操作系统上研究并实现基于DeviceNet现场总线的即插即用功能。
DeviceNet Fielbus, which oriented to object, is an open and device-level fieldbus. It is increasingly applied to industrial control areas now. Firstly, this paper introduces the transplant of μC/OS II based on arm7 platform. And then, it analyzes and implements of the plug-and-play function based on DeviceNet Fieldbus.
