過程控制

過程控制是指對(duì)溫度、壓力、流量、速度等連續(xù)變化的模擬量的閉環(huán)控制。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處理模擬量，完成閉環(huán)控制。PID調(diào)節(jié)是一般閉環(huán)控制系統(tǒng)中用得較多的一種調(diào)節(jié)方法。過程控制在冶金、化工、熱處理、鍋爐控制等場(chǎng)合有非常廣泛的應(yīng)用?，F(xiàn)代的大、中型PLC一般都有閉環(huán)PID控制模塊，這一功能可以用PID子程序來實(shí)現(xiàn)，而更多的是使用專用PID模塊來實(shí)現(xiàn)。

數(shù)據(jù)處理

PLC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、位操作等功能，可以完成數(shù)據(jù)的采集、分析及處理。這些數(shù)據(jù)可以通過通信接口傳送到指定的智能裝置進(jìn)行處理，或?qū)⑺鼈兇蛴溆谩?shù)據(jù)處理一般用于大型控制系統(tǒng)，如造紙、冶金、食品工業(yè)中的一些大型控制系統(tǒng)。

通信及聯(lián)網(wǎng)PLC通信括PLC相互之間、PLC與上位機(jī)、PLC與其它智能設(shè)備間的通信。PLC與其它智能控制設(shè)備一起，可以構(gòu)成“集中管理、分散控制”的分布式控制系統(tǒng)，滿足工廠自動(dòng)化系統(tǒng)發(fā)展的需要。

PLC控制系統(tǒng)與繼電器控制系統(tǒng)的區(qū)別：組成器件不同：繼電器控制線路是許多真正的硬件繼電器組成，而梯形圖則由許多所謂“軟繼電器”組成。

觸點(diǎn)數(shù)量不同：硬繼電器的觸點(diǎn)數(shù)量有限，用于控制的繼電器的觸點(diǎn)數(shù)一般只有4～8對(duì)；而梯形圖中每個(gè)“軟繼電器”供編程使用的觸點(diǎn)數(shù)有無限對(duì)。實(shí)施控制的方法不同：在繼電器控制線路中，實(shí)現(xiàn)某種控制是通過各種繼電器之間硬接線解決的。而PLC控制是通過梯形圖即軟件編程解決的。工作方式不同：在繼電器控制線路中，采用并行工作方式；而在梯形圖的控制線路中，采用串行工作方式。
