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，其"線圈"狀態(tài)只能由外部輸入信號(hào)驅(qū)動(dòng)。

PLC的各種功能主要是通過運(yùn)行控制程序來實(shí)現(xiàn)。編制程序時(shí)，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(shí)際上是PLC內(nèi)存區(qū)域所提供的一個(gè)二進(jìn)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(shí)（計(jì)數(shù)）器等，其參與控制的方式主要是通過對(duì)應(yīng)觸點(diǎn)的通斷狀態(tài)改變影響邏輯運(yùn)算結(jié)果即輸出。
字元件則為PLC內(nèi)存區(qū)域內(nèi)的一個(gè)字單元（16bit），主要用作功能指令和高級(jí)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(shí)(計(jì)數(shù))器的設(shè)定值SVn、經(jīng)過值EVn等。字元件沒有觸點(diǎn)，通常以整體內(nèi)容參與控制。
