界上公認(rèn)的臺(tái)PLC是1969年美國(guó)數(shù)字設(shè)備公司(DEC)研制的。限于當(dāng)時(shí)的元器件條件及計(jì)算機(jī)發(fā)展水平，早期的PLC主要由分立元件和中小規(guī)模集成電路組成，可以完成簡(jiǎn)單的邏輯控制及定時(shí)、計(jì)數(shù)功能。20世紀(jì)70年代初出現(xiàn)了微處理器。人們很快將其引入可編程控制器，使PLC增加了運(yùn)算、數(shù)據(jù)傳送及處理等功能，完成了真正具有計(jì)算機(jī)特征的工業(yè)控制裝置。為了方便熟悉繼電器、接觸器系統(tǒng)的工程技術(shù)人員使用，可編程控制器采用和繼電器電路圖類似的梯形圖作為主要編程語(yǔ)言，并將參加運(yùn)算及處理的計(jì)算機(jī)存儲(chǔ)元件都以繼電器命名。此時(shí)的PLC為微機(jī)技術(shù)和繼電器常規(guī)控制概念相結(jié)合的產(chǎn)物。
20世紀(jì)70年代中末期，可編程控制器進(jìn)入實(shí)用化發(fā)展階段，計(jì)算機(jī)技術(shù)已全面引入可編程控制器中，使其功能發(fā)生了飛躍。更高的運(yùn)算速度、超小型體積、更可靠的工業(yè)抗干擾設(shè)計(jì)、模擬量運(yùn)算、PID功能及極高的性價(jià)比奠定了它在現(xiàn)代工業(yè)中的地位。20世紀(jì)80年代初，可編程控制器在先進(jìn)工業(yè)國(guó)家中已獲得廣泛應(yīng)用。這個(gè)時(shí)期可編程控制器發(fā)展的特點(diǎn)是大規(guī)模、高速度、高性能、產(chǎn)品系列化。這個(gè)階段的另一個(gè)特點(diǎn)是上生產(chǎn)可編程控制器的國(guó)家日益增多，產(chǎn)量日益上升。這標(biāo)志著可編程控制器已步入成熟階段。
