摘　　要：现场总线在工业控制网络中作为底层的通信网络 ,成为自动化技术发展的一个热点 ,其中的DeviceNet现场总线以其高效性、低成本和高可靠性得到了广泛的应用。以断路器设备为例 ,提出了DeviceNet网络从节点的开发方案 ,设计了硬件电路 ,对断路器建立了具体对象模型 ,给出了DeviceNet协议的软件实现方法。使传统断路器具备了可通信的功能 ,同时对实现其他现场设备的可通信控制也具有借鉴意义。The communication network based on the fieldbus in the industrial control network has become a hotspot,the DeviceNet fieldbus has made a wide applications because of its high efficiency, low cost and high reliability. Take circuit breaker for example, the developing solutions for DeviceNet network slave node was brought out. The hard circuit design, and the specific object model of the circuit breaker were given,the realization method of software was also provided. The communication capable circuit breaker can be reference to other device.
