可編程控制器類型
4.1按控制規(guī)模分
控制規(guī)模主要指控制開關(guān)量的入、出點數(shù)及控制模擬量的模入、模出，或兩者兼而有之（閉路系統(tǒng)）的路數(shù)。但主要以開關(guān)量計。模擬量的路數(shù)可折算成開關(guān)量的點，大致一路相當(dāng)于8～16點。
依這個點數(shù)，PLC大致可分為微型機、小型機、中型機及大型機、超大型機。
微型機控制點僅幾十點，如德維森公司的V80系列PLC本體從16點到40點，OMRON公司的CPM1A系列PLC，西門子的Logo僅10點。
小型機控制點可達(dá)100多點。如如德維森公司的V80系列PLC可擴展到256點，OMRON公司的C60P可達(dá)148點，CQM1達(dá)256點。德國西門子公司的S7-200機可達(dá)64點。
中型機控制點數(shù)可達(dá)近500點，以至于千點。如德維森公司的PPC11系列可擴展到1024點，OMRON公司C200H機普通配置zui多可達(dá)700多點，C200Ha機則可達(dá)1000多點。德國西門子公司的S7300機zui多可達(dá)512點。
大型機：控制點數(shù)一般在1000點以上。如如德維森公司的PPC22系列可擴展到2048點，OMRON公司的C1000H、CV1000，當(dāng)?shù)嘏渲每蛇_(dá)1024點。C2000H、CV2000當(dāng)?shù)嘏渲每蛇_(dá)2048點。
超大型機：控制點數(shù)可達(dá)萬點，以至于幾萬點。如美國GE公司的90－70機，其點數(shù)可達(dá)24000點，另外還可有8000路的模擬量。再如美國*康公司的PC－E984--785機，其開關(guān)量具總數(shù)為32k（32768），模擬量有2048路。西門子的SS－115U－CPU945，其開關(guān)量總點數(shù)可達(dá)8k，另外還可有512路模擬量。等等。
以上這種劃分是不嚴(yán)格的，只是大致的，目的是便于系統(tǒng)的配置及使用。
一般講，根據(jù)實際的I/O點數(shù)，凡落在上述不同范圍者，選用相應(yīng)的機型，性能價格比必然要高；相反，肯定要差些。
自然，也有特殊情況。如控制點數(shù)不是非常之多，不是非用大型機不可，但因大型機的特殊控制單元多，可進(jìn)行熱備配置，因而采用了大型機。

4.2按結(jié)構(gòu)劃分
PLC可分為箱體式及模塊式兩大類。微型機、小型機多為箱體式的，但從發(fā)展趨勢看，小型機也逐漸發(fā)展成模塊式的了。如OMRON公司，原來小型機都是箱體式，現(xiàn)在的CQM1則為模塊式的。
箱體的PLC把電源、CPU、內(nèi)存、I/O系統(tǒng)都集成在一個小箱體內(nèi)。一個主機箱體就是一臺完整的PLC，就可用以實現(xiàn)控制。控制點數(shù)不符需要，可再接擴展箱體，由主箱體及若干擴展箱體組成較大的系統(tǒng)，以實現(xiàn)對較多點數(shù)的控制。
模塊式的PLC是按功能分成若干模塊，如CPU模塊、輸入模塊、輸出模塊、電源模塊等等。大型機的模塊功能更單一一些，因而模塊的種類也相對多些。這也可說是趨勢。目前一些中型機，其模塊的功能也趨于單一，種類也在增鄉(xiāng)。如同樣OMRON公司C20系列PLC，H機的CPU單元就含有電源，而Ha機則把電源分出，有單獨的電源模塊。
模塊功能更單一、品種更多，可便于系統(tǒng)配置，使PLC更能物盡其用，達(dá)到更高的使用效益。
