摘要
设计了一个基于P80C592的DeviceNet现场总线通信节点接口。主机部分采用8位高性能CAN微控制器P80C592,选择PCA82C251作为报文收发器,采用双口RAMIDT7005,并通过AnyBus接口来执行通信节点接口与现场智能测控单元的高速通信。实践应用证明论文所设计的DeviceNet通信节点接口可以完全实现DeviceNet规范的要求。
A P80C592based DeviceNet node interface is presented.P80C592is chosen as CPU of the system,82C251as the transceiver.Dual-port RAM IDT7005is used to realize high-speed communication between node interface and the intelligent measurement and control units.The practical application shows that the DeviceNet node interface can fully meet the demand of DeviceNet specification.
