可編程控制器類(lèi)型
4.1按控制規(guī)模分
控制規(guī)模主要指控制開(kāi)關(guān)量的入、出點(diǎn)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(kāi)關(guān)量計(jì)。模擬量的路數(shù)可折算成開(kāi)關(guān)量的點(diǎn)，大致一路相當(dāng)于8～16點(diǎn)。
依這個(gè)點(diǎn)數(shù)，PLC大致可分為微型機(jī)、小型機(jī)、中型機(jī)及大型機(jī)、超大型機(jī)。
微型機(jī)控制點(diǎn)僅幾十點(diǎn)，如德維森公司的V80系列PLC本體從16點(diǎn)到40點(diǎn)，OMRON公司的CPM1A系列PLC，西門(mén)子的Logo僅10點(diǎn)。
小型機(jī)控制點(diǎn)可達(dá)100多點(diǎn)。如如德維森公司的V80系列PLC可擴(kuò)展到256點(diǎn)，OMRON公司的C60P可達(dá)148點(diǎn)，CQM1達(dá)256點(diǎn)。德國(guó)西門(mén)子公司的S7-200機(jī)可達(dá)64點(diǎn)。
中型機(jī)控制點(diǎn)數(shù)可達(dá)近500點(diǎn)，以至于千點(diǎn)。如德維森公司的PPC11系列可擴(kuò)展到1024點(diǎn)，OMRON公司C200H機(jī)普通配置zui多可達(dá)700多點(diǎn)，C200Ha機(jī)則可達(dá)1000多點(diǎn)。德國(guó)西門(mén)子公司的S7300機(jī)zui多可達(dá)512點(diǎn)。
大型機(jī)：控制點(diǎn)數(shù)一般在1000點(diǎn)以上。如如德維森公司的PPC22系列可擴(kuò)展到2048點(diǎn)，OMRON公司的C1000H、CV1000，當(dāng)?shù)嘏渲每蛇_(dá)1024點(diǎn)。C2000H、CV2000當(dāng)?shù)嘏渲每蛇_(dá)2048點(diǎn)。
超大型機(jī)：控制點(diǎn)數(shù)可達(dá)萬(wàn)點(diǎn)，以至于幾萬(wàn)點(diǎn)。如美國(guó)GE公司的90－70機(jī)，其點(diǎn)數(shù)可達(dá)24000點(diǎn)，另外還可有8000路的模擬量。再如美國(guó)*康公司的PC－E984--785機(jī)，其開(kāi)關(guān)量具總數(shù)為32k（32768），模擬量有2048路。西門(mén)子的SS－115U－CPU945，其開(kāi)關(guān)量總點(diǎn)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(shí)際的I/O點(diǎn)數(shù)，凡落在上述不同范圍者，選用相應(yīng)的機(jī)型，性能價(jià)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(diǎn)數(shù)不是非常之多，不是非用大型機(jī)不可，但因大型機(jī)的特殊控制單元多，可進(jìn)行熱備配置，因而采用了大型機(jī)。

4.2按結(jié)構(gòu)劃分
PLC可分為箱體式及模塊式兩大類(lèi)。微型機(jī)、小型機(jī)多為箱體式的，但從發(fā)展趨勢(shì)看，小型機(jī)也逐漸發(fā)展成模塊式的了。如OMRON公司，原來(lái)小型機(jī)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(gè)小箱體內(nèi)。一個(gè)主機(jī)箱體就是一臺(tái)完整的PLC，就可用以實(shí)現(xiàn)控制。控制點(diǎn)數(shù)不符需要，可再接擴(kuò)展箱體，由主箱體及若干擴(kuò)展箱體組成較大的系統(tǒng)，以實(shí)現(xiàn)對(duì)較多點(diǎn)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(jī)的模塊功能更單一一些，因而模塊的種類(lèi)也相對(duì)多些。這也可說(shuō)是趨勢(shì)。目前一些中型機(jī)，其模塊的功能也趨于單一，種類(lèi)也在增鄉(xiāng)。如同樣OMRON公司C20系列PLC，H機(jī)的CPU單元就含有電源，而Ha機(jī)則把電源分出，有單獨(dú)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。
