外部輸入信號(hào)的采集

??? PLC的外部設(shè)備主要是指控制系統(tǒng)中的輸入輸出設(shè)備，其中輸人設(shè)備是對(duì)系統(tǒng)發(fā)出各種控制信號(hào)的主令電器，在編寫控制程序時(shí)必須注意外部輸入設(shè)備使用的是常開還是常閉觸點(diǎn)，并以此為基礎(chǔ)進(jìn)行程序編制。否則易出現(xiàn)控制錯(cuò)誤。

????在PLC內(nèi)部存儲(chǔ)器中有專用于輸入狀態(tài)存儲(chǔ)的輸入繼電器區(qū)，各輸入設(shè)備（開關(guān)、按鈕、行程開關(guān)或傳感器信號(hào)）的狀態(tài)經(jīng)由輸入接口電路存儲(chǔ)在該區(qū)域內(nèi)，每個(gè)輸入繼電器可存儲(chǔ)一個(gè)輸入設(shè)備狀態(tài)。PLC中使用的"繼電器"并非實(shí)體繼電器，而是"軟繼電器"，可提供無數(shù)個(gè)常開、常閉觸點(diǎn)用于編程。每個(gè)"軟繼電器"僅對(duì)應(yīng)PLC存儲(chǔ)單元中的一位（bit），該位狀態(tài)為"1"，表示該"軟繼電器線圈"通電，則程序中所有該繼電器的觸點(diǎn)都動(dòng)作。輸入繼電器作為PLC接收外部主令信號(hào)的器件，通過接線與外部輸入設(shè)備相聯(lián)系，其"線圈"狀態(tài)只能由外部輸入信號(hào)驅(qū)動(dòng)。輸入信號(hào)的采集工作示意圖如圖1。

輸入繼電器線圈其狀態(tài)取決于外部設(shè)備狀態(tài)
