1 ． 單元式
單元式的特點是結(jié)構(gòu)緊湊。它將所有的電路都裝入一個模塊內(nèi)，構(gòu)成一個整體，這樣體積小巧、成本低、安裝方便。
FX2 系列可編程控制器由基本單元、擴展單元、擴展模塊及特殊適配器等四種產(chǎn)品構(gòu)成。僅用基本單元或?qū)⑸鲜龈鞣N產(chǎn)品組合起來使用均可。
基本單元（ M ）：內(nèi)有 CPU 與存貯器，為*裝置。
擴展單元（ E ） : 要增加Ｉ／Ｏ點數(shù)時使用的裝置。
可利用擴展模塊，以 8 為單位增加輸入／輸出點數(shù)。也可只增加輸入點數(shù)或只增加輸出點數(shù)，因而使輸入／輸出的點數(shù)比率改變。
2 ．模塊式
模塊式可編程控制器采用搭積木的方式組成系統(tǒng)，在一塊基板上插上 CPU 、電源、Ｉ／Ｏ模塊及特殊功能模塊，構(gòu)成一個總Ｉ／Ｏ點數(shù)很多的大規(guī)模綜合控制系統(tǒng)。
這種結(jié)構(gòu)形式的特點是 CPU 為獨立的模塊 , 輸入、輸出也是獨立模塊。
3 ．疊裝式
它的結(jié)構(gòu)也是各種單元、 CPU 自成獨立的模塊，但安裝不用基板，僅用電纜進行單元間聯(lián)接，且各單元可以一層層地疊裝。
FX2 系列 PLC 是單元式和模塊式相結(jié)合的疊裝式結(jié)構(gòu)。
