仿真软件在PLC教学中的应用

Application of simulation software in PLC teaching

以十字路口交通信号灯为例,介绍了仿真软件在PLC教学中的应用。应用GX Developer编写程序,使用GX Simulator对程序仿真。应用GT Designer设计人机对话窗口,再用触摸屏仿真软件GT Simulator将人机对话窗口与PLC程序连接,实训对整个系统的仿真。结果显示,仿真软件节约了实验经费,缩短了试验周期,给教学带来了便利。

Based oncrossroads traffic lights control system as an example,introduces the application software in PLC teaching. Using GX Developer write the PLC program,using GX Simulator test control procedures. Using GT Designer to design the man-machine dialog window,and then touch screen simulation software GT Simulator man machine dialogue window is connected with the PLC program,realizes the simulation of the whole system. The results show that,the simulation software can be obtained and the on-line application consistent results,save experimental expenditure,shorten the cycle of the experiment brings convenient to study.
