摘要
本文介绍了一种采用冗余系统的可编程计算机控制器(PCC)如何与触摸屏进行快速切换的方法。通过运用POWERLINK总线,使贝加莱PCC与人机界面按照一个主站,多个从站的方式进行数据通信,实现了系统的无缝切换,增强了整个系统人机交互的能力。
This paper introduces a method of fast switching between a redundant programmable computer controller(PCC)and HMI.Through the use of POWERLINK bus,the b&r PCC and the man-machine interface can communicate with each other in the way of one master station and multiple slave stations.The seamless switching of the system is realized and increased the man-machine interaction ability of the whole system.
