PLC控制中央空調(diào)程序說明

1、PLC控制中央空調(diào)程序說明程序的設(shè)計關(guān)鍵是通過監(jiān)測外部溫度、蒸汽壓力等狀態(tài)調(diào)節(jié)幾個閥門（蒸汽閥、冷 水閥、溶液閥）以及溶劑泵、冷水泵等。巧妙之處是運用可逆計數(shù)器來記錄蒸汽閥和溶 液閥的開度，這樣減少了許多外部設(shè)備，使系統(tǒng)更趨簡單實用。PLC控制中央空調(diào)程序I/O注釋I/O程序中名稱意義1X0ZQFK.F蒸汽閥開反饋X1RUN開機運行X2STOP停機X3AUTO自動調(diào)節(jié)檔X4MUTE警鈴靜音X5TXTS水溫低X6PQPH氣壓過高X14HOTGF高發(fā)過熱X15ZQFG.F蒸汽閥關(guān)反饋X16JJIN結(jié)晶X17LSDW冷流水低溫X20LJSDW冷劑水低溫X21LS BUZU冷流水不足X22LQS BU
