1756-IN16/ABPLC模塊
為實(shí)現(xiàn)液位的手動(dòng)/自動(dòng)控制,需要輸入口12點(diǎn),輸出口8點(diǎn),選用C20P 20點(diǎn)I/O單元的PLC,輸入光電隔離,輸出繼電器隔離,負(fù)載能力強(qiáng);液位檢測(cè)采用干簧管傳感器,手動(dòng)/自動(dòng)轉(zhuǎn)換、運(yùn)行/試驗(yàn)轉(zhuǎn)換和液位設(shè)定采用雙位旋鈕,手動(dòng)啟泵、停泵和確認(rèn)、試驗(yàn)采用常開(kāi)按鈕;輸出選用電子音響報(bào)警器和24V直流指示燈、繼電器。參見(jiàn)圖一系統(tǒng)硬件配置圖。
為節(jié)省輸入口數(shù)量,節(jié)省投資,本系統(tǒng)運(yùn)行/試驗(yàn)功能的轉(zhuǎn)換采用了對(duì)I/O模塊接線(xiàn)的優(yōu)化,使PLC輸入模塊中1個(gè)輸入節(jié)點(diǎn)起到2個(gè)輸入節(jié)點(diǎn)的作用,完成PLC工作在兩種方式下的I/O功能。參見(jiàn)圖二I/O模塊接線(xiàn)的優(yōu)化。
