摘要
在PLC控制系统中引入人机界面可以简化系统的设计。通过操作触摸屏界面上的各种按钮可实现过程控制,系统的运行状态和各种I/O信号也可以通过触摸屏得以监视。本文基于某种工件检测的PLC控制系统介绍了三菱触摸屏的应用。通过实际生产运行,本系统具有可靠的控制性能,取得了良好的效果。
The introduction of man-machine interface in PLC control system can simplify the design of system.The process control is realized by touching the various buttons on the touch screen,and the running state of the system and all kinds of I/O signals can also be monitored by the touch screen.This paper intorduces the use of mitsubishi touch screen basing on a set of workpiece detection and control PLC system.This system is verified with reliable control performance and achieves good effect in the actual production.
