霓虹灯广告屏在我们的生活中已经随处可见,而且控制方式多变,故将PLC应用到霓虹灯广告屏中,依据PLC的设计的基本原理,通过对工程系统的分析确定以三菱中型号为FX2N-16M的PLC为主控器,基于GX-Develop软件,设计程序采用STL图编程方式,用顺序控制的设计思路开发控制程序,并逐步分析说明所设计程序运行功能,实现霓虹灯的闪烁循环,通过对霓虹灯及PLC控制的研究,论证了PLC控制技术在霓虹灯控制中的可行性。
Neon advertising screen in our life has been seen everywhere, and control changes, it will be applied to the neon screen advertising PLC, based on the basic principles of PLC design, through the analysis of the engineering system to determine the Mitsubishi Model FX2N- 16M PLC as the master, based on GX-Develop software, the design program adopts STL graph programming mode, uses the sequence control design idea to develop the control program, and gradually analyzes and explains the designed program running function, realizes the neon light twinkling cycle, Neon and PLC control of the study demonstrated the feasibility of PLC control technology in neon lights control.
