DeviceNet 是由美国ROCKWELL 公司于1994 年提出的,是目前世界领先的集中用于 工业自动化的设备级网络之一。本文设计了一个工业温控系统中的DeviceNet 接口电路,通过温度信号的改变,观测DeviceNet 组态软件中相应设备参数的变化,可以验证DeviceNet智能网卡实时多任务嵌入软件的实现。 关键字: DeviceNet;温度控制;接口 Abstract: Device Net is put forward by ROCKWELL corporation in 1994. It’s one of the most advanced device network which is used in the industrial automation. It designs a temperature-control system based on the DeviceNet intelligent card which can exchange data with remote controller on DeviceNet; so that it can present the communication card can work well.
