利用數(shù)據通信接口進行數(shù)據傳送和顯示，是實現(xiàn)PLC數(shù)據顯示的有效途徑。目前主流PLC均提供標準的RS-232或RS一485/422接口，或者通過模塊擴展增加此類接口。  
      三菱FX2N的通信模塊232ADP,232BD,485BD和485ADP均可作為數(shù)據接口。顯示裝置可選用智能顯示屏和通用計算機(PC).直接選用和PLC配套的顯示屏或觸摸屏，可實現(xiàn)PLC內部多個數(shù)據的集中顯示，并可利用編輯軟件編輯屏幕圖形，提高顯示界面的可視性。FX系列可配套的顯示屏有F93000T一BWD,F940GOT一LWD和F940GOT-SWD。智能顯示屏通過通信接口讀取PL的寄存器，數(shù)據顯示效率高，同時可簡化控制系統(tǒng)的設計。但由于顯示器的高成本，限制了大尺寸顯示屏的應用，因此該方法適合于緊湊型的PLC控制系統(tǒng)。隨著計算機性能和可靠性進一步提高，"PC+PLC"模式的控制系統(tǒng)在工業(yè)控制領域得到廣泛應用，PC機憑借豐富的軟硬件資源，可實現(xiàn)PLC的在線監(jiān)測，集中顯示大量的PLC內部數(shù)據，能以圖形化的方式顯示控制設備的動態(tài)工藝流程和數(shù)據趨勢曲線，使系統(tǒng)的人機界面直觀友好。  
    PLC與組太王的通信連接
    1：1一個站，距離<15米,用編程口驅動
    通過編程口通信(plc不需要進行編程)
    1：N多個站（zui多16個站），50米>距離>15米,用FX485驅動
    1：N多個站（zui多16個站），500米>距離>50米,用FX485驅動
    1：N多個站（zui多16個站），1200米>距離>500米,用FX485驅動（加485中繼）
        RS485的連線可以是一對或兩對導線。根據用途來決定連線的方法，本設計采用的是兩對導線連接方式。
      為了建立PLC與組太王的通信連接，可以在PLC編程軟件的菜單“PLC／串行口設置"中設置通信地址和通信參數(shù)，也可以在軟件中直接用編程(MOV指令)來實現(xiàn)，按RS485規(guī)定具體設置是：  
       波特率設為9600bit／s，數(shù)據位設為7位，l位起始位，2位停止位，偶校驗，采用協(xié)議1。用編程軟件設置,其中在D8121中設置通信地址。
