3.4.3PLC的發(fā)展趨勢
1. 向高速度、大容量、多功能、網(wǎng)絡(luò)化方向
發(fā)展
2. 向小型化、低成本、簡易實(shí)用方向發(fā)展
3. 提高系統(tǒng)的可靠性
4. 編程語言多樣化第4章FX2N系列PLC的硬件系統(tǒng)配置
? PLC 是一種專門用于工業(yè)控制的計算機(jī)。
為滿足不斷發(fā)展的大規(guī)模工業(yè)生產(chǎn)柔性控
制的要求而逐步發(fā)展起來的。最早用于取
代繼電器控制線路
其功能基本限于開關(guān)量邏輯控制,僅執(zhí)行
邏輯運(yùn)算、定時、計數(shù)等順序控制功能。
但隨著微電子技術(shù)和計算機(jī)技術(shù)的飛速發(fā)
展,PLC的功能已大大超出了原先的邏
輯運(yùn)算。可編程控制器是一種數(shù)字運(yùn)算操作的電子系統(tǒng),
專為在工業(yè)環(huán)境下應(yīng)用而設(shè)計。它采用可編程序
的存儲器,用來在其內(nèi)部存儲執(zhí)行邏輯運(yùn)算、順
序控制、定時、計數(shù)和算術(shù)運(yùn)算等操作的指令,
并通過數(shù)字的、模擬的輸入和輸出,控制各種類

易于擴(kuò)充其功能的原則設(shè)計。
