1 ． 单元式
单元式的特点是结构紧凑。它将所有的电路都装入一个模块内，构成一个整体，这样体积小巧、成本低、安装方便。
FX2 系列可编程控制器由基本单元、扩展单元、扩展模块及特殊适配器等四种产品构成。仅用基本单元或将上述各种产品组合起来使用均可。
基本单元（ M ）：内有 CPU 与存贮器，为*装置。
扩展单元（ E ） : 要增加Ｉ／Ｏ点数时使用的装置。
可利用扩展模块，以 8 为单位增加输入／输出点数。也可只增加输入点数或只增加输出点数，因而使输入／输出的点数比率改变。
2 ．模块式
模块式可编程控制器采用搭积木的方式组成系统，在一块基板上插上 CPU 、电源、Ｉ／Ｏ模块及特殊功能模块，构成一个总Ｉ／Ｏ点数很多的大规模综合控制系统。
这种结构形式的特点是 CPU 为独立的模块 , 输入、输出也是独立模块。
3 ．叠装式
它的结构也是各种单元、 CPU 自成独立的模块，但安装不用基板，仅用电缆进行单元间联接，且各单元可以一层层地叠装。
FX2 系列 PLC 是单元式和模块式相结合的叠装式结构。
