PLC的發(fā)展趨勢
    隨著PLC應(yīng)用領(lǐng)域日益擴(kuò)大，PLC技術(shù)及其產(chǎn)品結(jié)構(gòu)都在不斷改進(jìn)，功能日益強大，性價比越來越高。

    （1）、在產(chǎn)品規(guī)模方面，向兩極發(fā)展。一方面，大力發(fā)展速度更快、性價比更高的小型和超小型PLC。以適應(yīng)單機(jī)及小型自動控制的需要。另一方面，向高速度、大容量、技術(shù)完善的大型PLC方向發(fā)展。隨著復(fù)雜系統(tǒng)控制的要求越來越高和微處理器與計算機(jī)技術(shù)的不斷發(fā)展，人們對PLC的信息處理速度要求也越來越高，要求用戶存儲器容量也越來越大。
    （2）、向通信網(wǎng)絡(luò)化發(fā)展
    PLC網(wǎng)絡(luò)控制是當(dāng)前控制系統(tǒng)和PLC技術(shù)發(fā)展的潮流。PLC與PLC之間的聯(lián)網(wǎng)通信、PLC與上位計算機(jī)的聯(lián)網(wǎng)通信已得到廣泛應(yīng)用。目前，PLC制造商都在發(fā)展自己的通信模塊和通信軟件以加強PLC的聯(lián)網(wǎng)能力。各PLC制造商之間也在協(xié)商通用的通信標(biāo)準(zhǔn)，以構(gòu)成更大的網(wǎng)絡(luò)系統(tǒng)。PLC已成為集散控制系統(tǒng)（DCS）*的組成部分。

 （3）、向模塊化、智能化發(fā)展
    為滿足工業(yè)自動化各種控制系統(tǒng)的需要，近年來，PLC廠家先后開發(fā)了不少新器件和模塊，如智能I/O模塊、溫度控制模塊和專門用于檢測PLC外部故障的智能模塊等，這些模塊的開發(fā)和應(yīng)用不僅增強了功能，擴(kuò)展了PLC的應(yīng)用范圍，還提高了系統(tǒng)的可靠性。
    （4）、編程語言和編程工具的多樣化和標(biāo)準(zhǔn)化
    多種編程語言的并存、互補與發(fā)展是PLC軟件進(jìn)步的一種趨勢。 PLC廠家在使硬件及編程工具換代頻繁、豐富多樣、功能提高的同時，日益向MAP(制造自動化協(xié)議)靠攏，使PLC的基本部件，包括輸入輸出模塊、通信協(xié)議、編程語言和編程工具等方面的技術(shù)規(guī)范化和標(biāo)準(zhǔn)化。
