PLC在20世纪90年代已经形成微、小、中、大、巨型多种PLC。按I/O点数分，可分为微型PLC（32I/O）、小型PLC（256I/O）、中型PLC（1024I/O）、大型PLC（4.69I/O）、巨型PLC（8195I/O）五种。
PLC与工业生产过程的联系是通过I/O接口模块来实现的。PLC有许多I/O接口模块，包括开关量输入模块、开关量输出模块、模拟量输入模块、模拟量输出模块以及其他一些特殊模块，使用时应根据它们的特点进行选择。
（一）确定I/O点数
根据控制系统的要求确定所需要的I/O点数时，应再增加 10%～20%的备用量，以便随时增加控制功能。对于一个控制对象，由于采用的控制方法不同或编程水平不同，I/O点数也应有所不同。
