1、運(yùn)算功能

簡(jiǎn)單可編程邏輯控制器的運(yùn)算功能包括邏輯運(yùn)算、計(jì)時(shí)和計(jì)數(shù)功能；普通可編程邏輯控制器的運(yùn)算功能還包括數(shù)據(jù)移位、比較等運(yùn)算功能；較復(fù)雜運(yùn)算功能有代數(shù)運(yùn)算、數(shù)據(jù)傳送等；大型可編程邏輯控制器中還有模擬量的PID運(yùn)算和其他運(yùn)算功能。隨著開放系統(tǒng)的出現(xiàn)，在可編程邏輯控制器中都已具有通信功能，有些產(chǎn)品具有與下位機(jī)的通信，有些產(chǎn)品具有與同位機(jī)或上位機(jī)的通信，有些產(chǎn)品還具有與工廠或企業(yè)網(wǎng)進(jìn)行數(shù)據(jù)通信的功能。設(shè)計(jì)選型時(shí)應(yīng)從實(shí)際應(yīng)用的要求出發(fā)，合理選用所需的運(yùn)算功能。大多數(shù)應(yīng)用場(chǎng)合，只需要邏輯運(yùn)算和計(jì)時(shí)計(jì)數(shù)功能，有些應(yīng)用需要數(shù)據(jù)傳送和比較，當(dāng)用于模擬量檢測(cè)和控制時(shí)，才使用代數(shù)運(yùn)算，數(shù)值轉(zhuǎn)換和PID運(yùn)算等。要顯示數(shù)據(jù)時(shí)需要譯碼和編碼等運(yùn)算。

2、控制功能

控制功能包括PID控制運(yùn)算、前饋補(bǔ)償控制運(yùn)算、比值控制運(yùn)算等，應(yīng)根據(jù)控制要求確定?？删幊踢壿嬁刂破髦饕糜陧樞蜻壿嬁刂疲虼?，大多數(shù)場(chǎng)合常采用單回路或多回路控制器解決模擬量的控制，有時(shí)也采用專用的智能輸入輸出單元完成所需的控制功能，提高可編程邏輯控制器的處理速度和節(jié)省存儲(chǔ)器容量。例如采用PID控制單元、高速計(jì)數(shù)器、帶速度補(bǔ)償?shù)哪M單元、ASC碼轉(zhuǎn)換單元等。

3、通信功能

大中型可編程邏輯控制器系統(tǒng)應(yīng)支持多種現(xiàn)場(chǎng)總線和標(biāo)準(zhǔn)通信協(xié)議（如TCP/IP），需要時(shí)應(yīng)能與工廠管理網(wǎng)（TCP/IP）相連接。通信協(xié)議應(yīng)符合ISO/IEEE通信標(biāo)準(zhǔn)，應(yīng)是開放的通信網(wǎng)絡(luò)。

可編程邏輯控制器系統(tǒng)的通信接口應(yīng)包括串行和并行通信接口、RIO通信口、常用DCS接口等；大中型可編程邏輯控制器通信總線（含接口設(shè)備和電纜）應(yīng)1：1冗余配置，通信總線應(yīng)符合國際標(biāo)準(zhǔn)，通信距離應(yīng)滿足裝置實(shí)際要求。
