近年來PLC發(fā)展迅速 具備了計算機功能的一種通用工業(yè)控制裝置，成為現(xiàn)代工業(yè)自動化的三大技術(shù)支柱（PLC技術(shù)、機器人、CAD/CAM）之一。 PLC的分類 （1）按I/O點數(shù)分類； I/O點數(shù)在256以下為微型PLC；I/O點九在256~1024為中型PLC； I/O點數(shù)大于1024為大型PLC；I/O點數(shù)在4000以上為超大型PLC。 以上劃分不包括模擬量I/O點數(shù)，且劃分界限不是固定不變的。

（2）按結(jié)構(gòu)形式分類 1.整體式PLC：又稱單元式或箱體式。整體式PLC是將電源、CPU、I/O部件都集中裝在一個機箱內(nèi)。一般小型PLC采用這種結(jié)構(gòu)。

2.模塊式PLC：將PLC各部分分成若干個單獨的模塊，如CPU模塊、I/O模塊、電源模塊和各種功能模塊。模塊式PLC由框架和各種模塊組成。模塊插在插座上。一般大、中型PLC采用模塊式結(jié)構(gòu)，有的小型PLC也采用這種結(jié)構(gòu)。
