PLC在国内外已广泛应用于钢铁、石油、化工、电力、建材、机械制造、汽车、轻纺、交通运输、环保及文化娱乐等各个行业，使用情况主要分为如下几类：

　　1.开关量逻辑控制

　　取代传统的继电器电路，实现逻辑控制、顺序控制，既可用于单台设备的控制，也可用于多机群控及自动化流水线。如注塑机、印刷机、订书机械、组合机床、磨床、包装生产线、电镀流水线等。

　　2.工业过程控制

　　在工业生产过程当中，存在一些如温度、压力、流量、液位和速度等连续变化的量(即模拟量)，PLC采用相应的A/D和D/A转换模块及各种各样的控制算法程序来处理模拟量，完成闭环控制。PID调节是一般闭环控制系统中用得较多的一种调节方法。过程控制在冶金、化工、热处理、锅炉控制等场合有非常广泛的应用。

PLC has been widely used in steel, petroleum, chemical, electric power, building materials, machinery manufacturing, automobile, textile, transportation, environmental protection and cultural entertainment and other industries at home and abroad, the use is mainly divided into the following categories:

1. Switch quantity logic control

Instead of the traditional relay circuit, it can realize logic control and sequence control, which can be used for the control of a single device, and can also be used for multi-machine group control and automatic pipeline. Such as injection molding machines, printing presses, stapler machines, combined machine tools, grinding machines, packaging production lines, electroplating lines, etc.

2. Industrial process control

In the industrial production process, there are some continuous changes such as temperature, pressure, flow, liquid level and speed (that is, the analog amount), PLC uses the corresponding A/D and D/A conversion modules and a variety of control algorithms to deal with the analog amount, complete closed-loop control. PID regulation is a kind of regulation method used in general closed-loop control system. Process control is widely used in metallurgy, chemical industry, heat treatment, boiler control and so on.
