摘要
本文介绍了在舞台吊杆控制系统中,利用PLC的串行通信模块完成位置反馈信号采集和人机界面数据交换。实践表明,该方法可简化系统结构、降低成本。
This paper mainly introduces signal acquisition of height-feedback and data exchange of HMI using PLC＇s serial communication module in stage suspender; control system. According to the experiments, it is proved that the control system based on this method is more simple and low cost.
