PLC可編程控制器的特點
    1）、可靠性高，抗*力強。工業(yè)生產一般對控制設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*時間達到數萬小時以上，已被*為zui可靠的工業(yè)控制設備之一。
    PLC本身具有較強的自診斷功能，保證硬件核心設備（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。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)設計有完善的通道保護與信號調理電路。在結構上對耐熱、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更能適應工業(yè)現場環(huán)境要求。
    2） 硬件配套齊全，使用方便，適應性強
    PLC是通過執(zhí)行程序實現控制的。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的產品已標準化、系列化、模塊化，而且PLC及配套產品的模塊品種多，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的端子上接入相應的輸入/輸出信號線即可，不需要進行大量且復雜的硬接線，并且PLC有較強的帶負載能力，可以直接驅動一般的電磁閥和交流接觸器。

3）、編程直觀、易學易會
    PLC提供了多種編程語言，其中梯形圖使用zui普遍。PLC是面向用戶的設備，PLC的設計者充分考慮到現場工程技術人員的技能和習慣，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，易學易懂，不需要專門的計算機知識和語言，現場工程技術人員可在短時間內學會使用。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應用于生產實踐。
