整体式又叫做单元式或机箱式，它的体积小、价格低，对箱体式PLC，有一块CPU板、I/O板、显示面板、内存块、电源等，当然按CPU性能分成若干型号，并按I/O点数又有若干规格。对模块式PLC，有CPU模块、I/O模块、内存、电源模块、底板或机架。无任哪种结构类型的PLC，都属于总线式开放型结构，其I/O能力可按用户需要进行扩展与组合。
大、中型PLC一般采用模块式结构，它由机架和模块组成，模块插在模块插座上，后者焊接在机架中的总线连接板上，有不同槽数的机架供用户选用，如果一个机架容纳不下选用的模块，可以增设一个或数个扩展机架，各机架之间用接口模块和电缆相连。
用户可以选用不同档次的CPU模块、品种繁多的I/O模块和特殊功能块，对硬件配置的选择余地较大，维修时更换模块也很方便。
