目前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。在运城电厂主要有化学制水、生活污水处理、工业废水处理、凝结水精处理等。有关PLC的使用情况主要分为如下几类。
1 开关
开关是最常见的电子元件，功能就是电路的接通和断开。接通则电流可以通过，反之电流无法通过。在各种电子设备、家用电器中都可以见到开关。 PLC可以方便地实现逻辑控制取代传统的继电器。
继电器是我们生活中常用的一种控制设备，通俗的意义上来说就是开关，在条件满足的情况下关闭或者开启。继电器的开关特性在很多的控制系统尤其是离散的控制系统中得到广泛的应用。从另一个角度来说，由于为某一个用途设计使用的电子电路，最终或多或少都需要和某一些机械设备相交互，所以继电器也起到电子设备和机械设备的接口作用。
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。如水泵的启停、阀门的开关、制水系统顺控、干除灰系统等。
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
3 运动控制
PLCC
4 数据处理
PLCC具有数学运算(含矩阵运算、函数运算、逻辑运算)、数据传送、数据转换、排序、查表等功能，可以完成数据的采集,
5 通信及联网
PLCC通信含PLC间的通信及PLC与其他智能设备间的通信。随着工厂自动化网络的发展，现在的PLC都具有通信接口，通信非常方便。
