摘　　要：针对工业控制过程中经常需要同时使用多品牌控制器组建控制系统的问题,基于ARM9工业触摸屏及嵌入式HMI软件,以台达DVP系列PLC和三菱FX系列PLC为例对工业触摸屏同时与多品牌的多个PLC的通信进行研究,借助嵌入式HMI软件良好的人机界面实现对多品牌多PLC控制系统中的设备进行实时通信。该方案同样适用于在控制系统中使用了其他具有通信功能的控制器,如伺服放大器、温控模块等的场合。In light of the problem that in industry control process there often has the need to use the controllers in multiple brands simultaneously to form the control system,in this article,we study the simultaneous communication between the industrial touch screen and multiple PLCs in multiple brands,which takes the PLC of Delta DVP series and of Mitsubishi FX series as the example,and is based on ARM9 industrial touch screen and the embedded HMI software.In the study we have achieved real-time communication of the equipments in multiple PLC control systems in multiple brands with the help of preferable human-computer interface of embedded HMI software.This scheme can also be applied to the controllers with other communication functions in control system,such as servo amplifier,temperature control module and so on.
