PLC的外部設備主要是指控制系統中的輸入輸出設備，其中輸人設備是對系統發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備使用的是常開還是常閉觸點，并以此為基礎進行程序編制。否則易出現控制錯誤。
在PLC內部存儲器中有于輸入狀態存儲的輸入繼電器區，各輸入設備（開關、按鈕、行程開關或傳感器信號）的狀態經由輸入接口電路存儲在該區域內，每個輸入繼電器可存儲一個輸入設備狀態。PLC中使用的"繼電器"并非實體繼電器，而是"軟繼電器"，可提供無數個常開、常閉觸點用于編程。每個"軟繼電器"僅對應PLC存儲單元中的一位（bit），該位狀態為"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備相，其"線圈"狀態只能由外部輸入信號驅動。

PLC的各種功能主要是通過運行控制程序來實現。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內存區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、內部通用繼電器Rn、定時（計數）器等，其參與控制的方式主要是通過對應觸點的通斷狀態改變影響邏輯運算結果即輸出。
字元件則為PLC內存區域內的一個字單元（16bit），主要用作功能指令和高級指令的編程元件，通常用以存放數據，如數據寄存器DTn，定時(計數)器的設定值SVn、經過值EVn等。字元件沒有觸點，通常以整體內容參與控制。
