目前PLC在國(guó)內(nèi)外已廣泛應(yīng)用于鋼鐵、石油、化工、電力、建材、機(jī)械制造、汽車、輕紡、交通運(yùn)輸、環(huán)保及文化娛樂(lè)等各個(gè)行業(yè)。在運(yùn)城電廠主要有化學(xué)制水、生活污水處理、工業(yè)廢水處理、凝結(jié)水精處理等。有關(guān)PLC的使用情況主要分為如下幾類。

1 開(kāi)關(guān)

開(kāi)關(guān)是最常見(jiàn)的電子元件，功能就是電路的接通和斷開(kāi)。接通則電流可以通過(guò)，反之電流無(wú)法通過(guò)。在各種電子設(shè)備、家用電器中都可以見(jiàn)到開(kāi)關(guān)。 PLC可以方便地實(shí)現(xiàn)邏輯控制取代傳統(tǒng)的繼電器。

繼電器是我們生活中常用的一種控制設(shè)備，通俗的意義上來(lái)說(shuō)就是開(kāi)關(guān)，在條件滿足的情況下關(guān)閉或者開(kāi)啟。繼電器的開(kāi)關(guān)特性在很多的控制系統(tǒng)尤其是離散的控制系統(tǒng)中得到廣泛的應(yīng)用。從另一個(gè)角度來(lái)說(shuō)，由于為某一個(gè)用途設(shè)計(jì)使用的電子電路，最終或多或少都需要和某一些機(jī)械設(shè)備相交互，所以繼電器也起到電子設(shè)備和機(jī)械設(shè)備的接口作用。

   電路，實(shí)現(xiàn)邏輯控制、順序控制，既可用于單臺(tái)設(shè)備的控制，也可用于多機(jī)群控。如水泵的啟停、閥門的開(kāi)關(guān)、制水系統(tǒng)順控、干除灰系統(tǒng)等。

2 工業(yè)過(guò)程控制

在工業(yè)生產(chǎn)過(guò)程當(dāng)中，存在一些如溫度、壓力、流量、液位和速度等連續(xù)變化的量量(即模擬量)，PLC采用相應(yīng)的A／D和D／A轉(zhuǎn)換模塊及各種各樣的控制算法程序來(lái)處理模擬量，完成閉環(huán)控制。PID

3 運(yùn)動(dòng)控制

PLCC

4 數(shù)據(jù)處理

PLCC具有數(shù)學(xué)運(yùn)算(含矩陣運(yùn)算、函數(shù)運(yùn)算、邏輯運(yùn)算)、數(shù)據(jù)傳送、數(shù)據(jù)轉(zhuǎn)換、排序、查表等功能，可以完成數(shù)據(jù)的采集,

5 通信及聯(lián)網(wǎng)

PLCC通信含PLC間的通信及PLC與其他智能設(shè)備間的通信。隨著工廠自動(dòng)化網(wǎng)絡(luò)的發(fā)展，現(xiàn)在的PLC都具有通信接口，通信非常方便。
