過程控制是指對(duì)溫度、壓力、流量等連續(xù)變化的模擬量的閉環(huán)控制。PLC通過模擬量I/O模塊，實(shí)現(xiàn)模擬量（Analog）和數(shù)字量（Digital）之間的A/D轉(zhuǎn)換和D/A轉(zhuǎn)換。并對(duì)模擬量實(shí)行閉環(huán)PID控制?，F(xiàn)代的大中型PLC一般都有PID閉環(huán)控制功能，這一功能可以用的智能PID模塊PID子程序來實(shí)現(xiàn)，也可以設(shè)計(jì)PID子程序來完成，更多的使用PID功能指令來完成。PLC的模擬量PID控制功能已經(jīng)廣泛地應(yīng)用于塑料擠壓成型機(jī)、加熱爐、熱處理爐、鍋爐等設(shè)備，以及輕工、化工、機(jī)械、冶金、電力、建材等行業(yè)。

現(xiàn)代的PLC具有數(shù)學(xué)運(yùn)算（包括矩陣運(yùn)算、函數(shù)運(yùn)算、邏輯運(yùn)算）、數(shù)據(jù)運(yùn)算、轉(zhuǎn)換、排序和查表、位操作等功能，可以完成數(shù)據(jù)的采集、分析和處理。這些數(shù)據(jù)可以與儲(chǔ)存在存儲(chǔ)器中的參考值比較，也可以用通信功能傳到別的智能裝置，或者將他們打印制表，數(shù)據(jù)處理一般用于大型控制系統(tǒng)，如無人柔性制造系統(tǒng)，也可以用于過程控制系統(tǒng)，如造紙、冶金、食品工業(yè)中的一些大型控制系統(tǒng)。
