Using the PLC to control digital control bined with touch screen remote operation and monitoring functions, the high reliability of the system, programming, missioning and operation and maintenance simple, especially for plex control system, the advantage is more obvious. Mitsubishi PLC controlled digital display, touch screen and PLC munications, digital control of the status display on the touch screen and even control on the touch screen digital control. This paper first introduces the history and development of the PLC, and then were analyzed for PLC selection and FX series PLC overview. Then the Mitsubishi PLC programming software (GX Developer), Mitsubishi touch screen programming software (GT Designer2) as well as Mitsubishi touch screen A960GOT. Keywords: PLC, Mitsubishi touch screen A960GOT ， eight out LED digital tube,GX Developer GT designer2 惠州學(xué)院 2021 屆畢業(yè)論文（設(shè)計(jì)） 前言 .................................................................................................................................................. 1 第一章 緒論 .................................................................................................................................... 2 PLC 的介紹 ........................................................................................................................ 2 PLC 的發(fā)展過程 ....................................................................................................... 2 PLC 的發(fā)展趨勢 ....................................................................................................... 2 PLC 的主要特點(diǎn) ..................................................................................................... 3 PLC 的組成 ............................................................................................................ 4 PLC 和觸摸屏在 LED 數(shù)碼管控制中的應(yīng)用的意義 ........................................................... 8 第二章 PLC 控制 LED 數(shù)碼管顯示設(shè)計(jì) ....................................................................................... 9 PLC 編程軟件選擇 .......................................................................................................... 9 確定顯示時(shí)各段的電平情況 ............................................................................................. 9 確定 PLC 的 I/O 點(diǎn)的分配 ............................................................................................. 10 程序梯形圖 .....................................................................................................................11 第三章 觸摸屏界面設(shè)計(jì) ............................................................................................................. 23 觸摸屏簡介 .................................................................................................................... 23 觸摸屏編程、仿真軟件選擇 ........................................................................................... 23 監(jiān)控界面的設(shè)計(jì) ............................................................................................................. 23 新建工程 ............................................................................................................. 23 操作界面的建立 .................................................................................................. 26 第四章 PLC 與觸摸屏的通信 .........................................................................
