通訊及聯網
PLC通訊含PLC間的通訊及PLC與其它智能設備間的通訊。隨著計算機操控的開展，工廠自動化網絡開展得很快，各PLC廠商都十分重視PLC的通訊功用，紛繁推出各自的網絡體系。新近出產的PLC都具有通訊接口，通訊十分便利。
PLC常用程序規劃言語:
在可編程操控器中有多種程序規劃言語,它們是梯形圖言語、布爾助記符言語、功用表圖言語、功用模塊圖言語及結構化句子描繪言語等。梯形圖言語和布爾助記符言語是根本程序規劃言語，它通常由一系列指令構成，用這些指令能夠完結大多數簡略的操控功用，例如，替代繼電器、計數器、計時器完結次第操控和邏輯操控等，經過拓展或增強指令集，它們也能履行其它的根本操作。功用表圖言語和句子描繪言語是高檔的程序規劃言語，它可依據需求去履行更有用的操作，例如，模擬量的操控，數據的操作，報表的報印和別的根本程序規劃言語無法完結的功用。功用模塊圖言語選用功用模塊圖的辦法，經過軟銜接的辦法完結所請求的操控功用，它不僅在可編程序操控器中得到了廣泛的運用，在集散操控體系的編程和組態時也常常被選用，因為它具有銜接便利、操作簡略、易于把握等特色，為廣闊工程規劃和運用人員所喜歡。
依據可編程器運用規劃，程序規劃言語能夠組合運用，常用的程序規劃言語是：梯形圖程序規劃言語 、 布爾助記符程序規劃言語（句子表）、功用表圖程序規劃言語 、功用模塊圖程序規劃言語、 結構化句子描繪程序規劃言語、 梯形圖與結構化句子描繪程序規劃言語、 布爾助記符與功用表圖程序規劃言語、 布爾助記符與結構化句子描繪程序規劃言語。
