基于DeviceNet现场总线智能阀控制器通信接口设计

The DeviceNet Communication Interface Designing on Smart Valve Controller

基于CAN技术的DeviceNet是一种低成本的通信总线,它将各种工业设备连接到网络。智能阀控制器通信接口是用于智能阀控制器与DeviceNet网络之间的通信协议设备,在智能阀控制器和DeviceNet网络主设备之间交换I/O数据和其他设定数据。本文对该通信接口给出了其硬件及软件的设计。

The DeviceNet based on the CAN technology is a kind of low cost communication bus.It can connect various equipments to the network.The communication interface on smart valve controller is the device based on the protocol between the valve controller and Devicenet Net, which is used for exchanging I/O data and setting message. The papers mention the hardware design and software design of that communication interface.
