1．輸入/輸出單元

輸入/輸出單元通常也稱I/O單元或I/O模塊，是PLC與工業(yè)生產(chǎn)現(xiàn)場之間的連接部件。

PLC通過輸入接口可以檢測被控對(duì)象的各種數(shù)據(jù)，以這些數(shù)據(jù)作為PLC對(duì)被控制對(duì)象進(jìn)行控制的依據(jù)；同時(shí)PLC又通過輸出接口將處理結(jié)果送給被控制對(duì)象，以實(shí)現(xiàn)控制目的。

由于外部輸入設(shè)備和輸出設(shè)備所需的信號(hào)電平是多種多樣的，而PLC內(nèi)部CPU的處理的信息只能是標(biāo)準(zhǔn)電平，所以I/O接口要實(shí)現(xiàn)這種轉(zhuǎn)換。

I/O接口一般都具有光電隔離和濾波功能，以提高PLC的抗干擾能力。另外，I/O接口上通常還有狀態(tài)指示，工作狀況直觀，便于維護(hù)。

PLC提供了多種操作電平和驅(qū)動(dòng)能力的I/O接口，有各種各樣功能的I/O接口供用戶選用。I/O接口的主要類型有：數(shù)字量（開關(guān)量）輸入、數(shù)字量（開關(guān)量）輸出、模擬量輸入、模擬量輸出等。

常用的開關(guān)量輸入接口按其使用的電源不同有三種類型：直流輸入接口、交流輸入接口和交/直流輸入接口。

常用的開關(guān)量輸出接口按輸出開關(guān)器件不同有三種類型：是繼電器輸出、晶體管輸出和雙向晶閘管輸出。

繼電器輸出接口可驅(qū)動(dòng)交流或直流負(fù)載，但其響應(yīng)時(shí)間長，動(dòng)作頻率低；而晶體管輸出和雙向晶閘管輸出接口的響應(yīng)速度快，動(dòng)作頻率高，但前者只能用于驅(qū)動(dòng)直流負(fù)載，后者只能用于交流負(fù)載。

PLC的I/O接口所能接受的輸入信號(hào)個(gè)數(shù)和輸出信號(hào)個(gè)數(shù)稱為PLC輸入/輸出（I/O）點(diǎn)數(shù)。I/O點(diǎn)數(shù)是選擇PLC的重要依據(jù)之一。當(dāng)系統(tǒng)的I/O點(diǎn)數(shù)不夠時(shí)，可通過PLC的I/O擴(kuò)展接口對(duì)系統(tǒng)進(jìn)行擴(kuò)展。

2．通信接口

PLC配有各種通信接口，這些通信接口一般都帶有通信處理器。

PLC通過這些通信接口可與監(jiān)視器、打印機(jī)、其它PLC、計(jì)算機(jī)等設(shè)備實(shí)現(xiàn)通信。

PLC與打印機(jī)連接，可將過程信息、系統(tǒng)參數(shù)等輸出打??；與監(jiān)視器連接，可將控制過程圖像顯示出來；與其它PLC連接，可組成多機(jī)系統(tǒng)或連成網(wǎng)絡(luò)，實(shí)現(xiàn)更大規(guī)?？刂?。

與計(jì)算機(jī)連接，可組成多級(jí)分布式控制系統(tǒng)，實(shí)現(xiàn)控制與管理相結(jié)合。遠(yuǎn)程I/O系統(tǒng)也必須配備相應(yīng)的通信接口模塊。

3．智能接口模塊

智能接口模塊是一獨(dú)立的計(jì)算機(jī)系統(tǒng)，它有自己的CPU、系統(tǒng)程序、存儲(chǔ)器以及與PLC系統(tǒng)總線相連的接口。

它作為PLC系統(tǒng)的一個(gè)模塊，通過總線與PLC相連，進(jìn)行數(shù)據(jù)交換，并在PLC的協(xié)調(diào)管理下獨(dú)立地進(jìn)行工作。

PLC的智能接口模塊種類很多，如：高速計(jì)數(shù)模塊、閉環(huán)控制模塊、運(yùn)動(dòng)控制模塊、中斷控制模塊等。
