PLC可編程控制器的特點
1）、可靠性高，抗*力強。工業(yè)生產(chǎn)一般對控制設(shè)備的可靠性要求很高，并且要有很強的抗*力。PLC能在惡劣的環(huán)境中可靠的工作，平均*時間達到數(shù)萬小時以上，已被*為zui可靠的工業(yè)控制設(shè)備之一。
PLC本身具有較強的自診斷功能，保證硬件核心設(shè)備（CPU、存儲器、I/O總線等）在正常情況下執(zhí)行用戶程序，一旦出現(xiàn)故障則立即給出出錯信號，停止用戶程序的執(zhí)行，切斷所有輸出信號，等待修復(fù)。PLC的主要模塊均采用大規(guī)模和超大規(guī)模集成電路，I/O系統(tǒng)設(shè)計有完善的通道保護與信號調(diào)理電路。在結(jié)構(gòu)上對耐熱、防潮、防塵、抗震等都有精確的考慮，在硬件上采用隔離，屏蔽、濾波、接地等抗干擾措施，在軟件上采用數(shù)字濾波等措施。與繼電器系統(tǒng)和通用計算機相比，PLC更能適應(yīng)工業(yè)現(xiàn)場環(huán)境要求。
2） 硬件配套齊全，使用方便，適應(yīng)性強
PLC是通過執(zhí)行程序?qū)崿F(xiàn)控制的。當控制要求發(fā)生改變時，只要修改程序即可，zui大限度地縮短了工藝更新所需要的時間。PLC的產(chǎn)品已標準化、系列化、模塊化，而且PLC及配套產(chǎn)品的模塊品種多，用戶可以靈活方便地進行系統(tǒng)配置組合成各種不同規(guī)模、不同功能的控制系統(tǒng)。在PLC控制系統(tǒng)中，只需在PLC的端子上接入相應(yīng)的輸入/輸出信號線即可，不需要進行大量且復(fù)雜的硬接線，并且PLC有較強的帶負載能力，可以直接驅(qū)動一般的電磁閥和交流接觸器。

3）、編程直觀、易學(xué)易會
PLC提供了多種編程語言，其中梯形圖使用zui普遍。PLC是面向用戶的設(shè)備，PLC的設(shè)計者充分考慮到現(xiàn)場工程技術(shù)人員的技能和習(xí)慣，因此PLC程序的編制采用梯形圖的簡單指令形式。梯形圖與繼電原理圖相似，這種編程語言形象直觀，易學(xué)易懂，不需要專門的計算機知識和語言，現(xiàn)場工程技術(shù)人員可在短時間內(nèi)學(xué)會使用。用戶在購買PLC后，只需按說明書的提示，做少量的接線和進行簡易的用戶程序編制工作，就可靈活方便地將PLC應(yīng)用于生產(chǎn)實踐。
