DeviceNet智能节点的开发

DeviceNet是基于CAN技术的开放型低成本高性能的通信网络，它已成为IEC标准与欧洲标准，以智能开关为例，提出了DeviceNet产品的开发方案，设计出了DesviceNet节点的硬件电路，建立了其对象模型，讨论了各对象之间的关系，以及每个对象实例和对象所提供的服务及产生的行为，同时阐述了软件实现的方法，并通过对智能开关的测试，证明了此开发方案是可行的。

Development of DeviceNet Intelligent Node

DeviceNet is an open, low cost and high performance communication network based on CAN technology, and it has become IEC standard and Europe standard. Take intelligent switch for example, it brings out the developing solutions for DeviceNet products; gives a hard circuit design for DeviceNet node, builds up object model and discusses the relationship between the objects. Each object for instance and service and behavior provided by object class and realization method of software was expatiated. It is validated to be feasible by the experiment on intelligent switch.
