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)備是對系統(tǒng)發(fā)出各種控制信號的主令電器,在編寫控制程序時必須注意外部輸入設(shè)備使用的是常開還是常閉觸點,并以此為基礎(chǔ)進行程序編制。否則易出現(xiàn)控制錯誤。
在PLC內(nèi)部存儲器中有于輸入狀態(tài)存儲的輸入繼電器區(qū),各輸入設(shè)備(開關(guān)、按鈕、行程開關(guān)或傳感器信號)的狀態(tài)經(jīng)由輸入接口電路存儲在該區(qū)域內(nèi),每個輸入繼電器可存儲一個輸入設(shè)備狀態(tài)。PLC中使用的"繼電器"并非實體繼電器,而是"軟繼電器",可提供無數(shù)個常開、常閉觸點用于編程。每個"軟繼電器"僅對應(yīng)PLC存儲單元中的一位(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都動作。輸入繼電器作為PLC接收外部主令信號的器件,通過接線與外部輸入設(shè)備相,其"線圈"狀態(tài)只能由外部輸入信號驅(qū)動。

PLC的各種功能主要是通過運行控制程序來實現(xiàn)。編制程序時,需要合理使用PLC提供的編程元件(即軟元件)。FPO型PLC中常用的編程元件有兩種:位元件(bit)和字元件(word)。位元件實際上是PLC內(nèi)存區(qū)域所提供的一個二進制位單元,又被稱為軟繼電器,主要用作基本順序指令的編程元件,如輸入繼電器Xn、輸出繼電器Yn、內(nèi)部通用繼電器Rn、定時(計數(shù))器等,其參與控制的方式主要是通過對應(yīng)觸點的通斷狀態(tài)改變影響邏輯運算結(jié)果即輸出。
字元件則為PLC內(nèi)存區(qū)域內(nèi)的一個字單元(16bit),主要用作功能指令和高級指令的編程元件,通常用以存放數(shù)據(jù),如數(shù)據(jù)寄存器DTn,定時(計數(shù))器的設(shè)定值SVn、經(jīng)過值EVn等。字元件沒有觸點,通常以整體內(nèi)容參與控制。
