摘要
设计了一个基于DeviceNet现场总线的智能泵 /阀控制器接口。主机部分采用 80C196KC单片机 ;选择SJA10 0 0作为CAN控制器 ,82C2 5 1作为报文收发器 ;采用双口RAMIDT70 0 5 ,并通过AnyBus接口执行控制器接口与现场智能测控单元的高速通信。实践证明 ,该智能泵 /阀控制器接口能实现DeviceNet规范的要求。
An interface to intelligent pump/valve controller is designed based on DeviceNet fieldbus. Concretely, the 80C196KC single chip computer is used as the main part, SJA1000 is selected for CAN controller, and 82C251 for message transceiver. The high speed communication between controller interface and field intelligent measuring and controlling unit is implemented by using dual port RAM IDT7005 and through AnyBus interface. The practice shows that the interface is able to realize the requirements stated in Devicenet specification. Key words Interface Intelligent pump/valve Controller DeviceNet Fieldbus
