第一个PLC控制器是简单的设备。他们连接输入，例如开关、数字传感器等，或者基于内部逻辑打开/关闭外部设备。当他们首次出现的时候，还不很适合复杂的控制，例如温度、位置、压力，等等。但是，经过一些年的改进，PLC控制器的制造商增加了许多特性和改进。今天的PLC控制器已经可以处理高度复杂的任务，例如位置控制，不同规则控制以及其他复杂的应用。工作速度和编程的简易性也都得到改善。而且，还开发了专门用途的模块，像将几个PLC控制器连接成网络的通信模块。现在很难想象有不使用PLC控制的工作。
从结构上分，PLC分为固定式和组合式（模块式）两种。固定式PLC包括CPU板、I/O板、显示面板、内存块、电源等，这些元素组合成一个不可拆卸的整体。模块式PLC包括CPU模块、I/O模块、内存、电源模块、底板或机架，这些模块可以按照一定规则组合配置。

The first PLC controller is simple equipment.They connected inputs, such as switches, digital sensors, or based on internal logic open/close external devices.When they first came up, also not very suitable for complicated control, such as temperature, position, pressure, etc.However, after a few years of improvement, PLC controller manufacturers increased a lot of characteristics and improvement.Today's PLC controller can handle highly complex tasks, such as position control, various rules and other complex applications.The speed of work and easiness of programming are improved. And also developing modules for special purposes, such as connecting several PLC controllers network communication module.
Now it is hard to imagine not using PLC control work.
From the structure, PLC is divided into fixed and combined modular (two).Fixed PLC including CPU boards, I/O board, display panel, memory, etc, these elements into a not remove the whole.Module type PLC including CPU
