電源部分
PLC內(nèi)部配有一個(gè)開關(guān)型穩(wěn)壓電源，它將交流／直流供電電源變換成系統(tǒng)內(nèi)部各單元所需的電源，即為PLC各模塊的集成電路提供工作電源。
PLC一般使用220V的交流供電電源。PLC內(nèi)部的開關(guān)電源對(duì)電網(wǎng)提供的電源要求不高，與普通電源相比，PLC電源穩(wěn)定性好、抗*力強(qiáng)。許多PLC都向外提供直流24V穩(wěn)壓電源，用于對(duì)外部傳感器供電。
對(duì)于整體式結(jié)構(gòu)的PLC，通常電源封裝在機(jī)殼內(nèi)部；對(duì)于模塊式PLC，有的采用單獨(dú)電源模塊，有的將電源與PLC封裝到一個(gè)模塊中。
5）、編程器
編程器是PLC開發(fā)應(yīng)用、監(jiān)測(cè)運(yùn)行、檢查維護(hù)*的器件。它是PLC的外部設(shè)備，是人機(jī)交互的窗口?？捎糜诰幊?、對(duì)系統(tǒng)作一些設(shè)定、監(jiān)控PLC及PLC所控制的系統(tǒng)的工作狀況，但它不直接參與現(xiàn)場(chǎng)控制運(yùn)行。編程器可以是編程器，也可以是配有編程軟件包的通用計(jì)算機(jī)系統(tǒng)。編程器是由PLC生產(chǎn)廠家，該廠家生產(chǎn)的某些PLC產(chǎn)品使用，使用范圍有限，價(jià)格較高。目前，大多是使用個(gè)人計(jì)算機(jī)為基礎(chǔ)的編程器，用戶只要購(gòu)買PLC廠家提供的編程軟件和相應(yīng)的硬件接口裝置，就可以得到高性能的PLC程序開發(fā)系統(tǒng)。

6）、擴(kuò)展接口和外設(shè)通信接口
(1）外設(shè)通信接口
PLC配有多種通信接口，PLC通過(guò)這些通信接口可與編程器、打印機(jī)、其它PLC、計(jì)算機(jī)等設(shè)備實(shí)現(xiàn)通信?？山M成多機(jī)系統(tǒng)或連成網(wǎng)絡(luò)，實(shí)現(xiàn)更大規(guī)?？刂?。
