(2)中檔PLC除具有低檔PLC的功能外,還具有較強(qiáng)的模擬量輸入/輸出、算術(shù)運(yùn)算、數(shù)據(jù)傳送和比較、數(shù)制轉(zhuǎn)換、遠(yuǎn)程I/O、子程序、通信聯(lián)網(wǎng)等功能。有些還可增設(shè)中斷控制、PID控制等功能,適用于復(fù)雜控制系統(tǒng)。
在當(dāng)今經(jīng)濟(jì)競(jìng)爭(zhēng)激烈的環(huán)境下,制造工藝的細(xì)小改進(jìn)可產(chǎn)生巨大的競(jìng)爭(zhēng)優(yōu)勢(shì)。這種觀念正在驅(qū)使工廠車間發(fā)生根本性的轉(zhuǎn)變。制造商正在部署***的傳感器技術(shù),采用新的控制架構(gòu),并開始挖掘“大數(shù)據(jù)”和數(shù)據(jù)分析的潛力。
可編程序控制器,英文稱Programmable Controller,簡(jiǎn)稱PC。但由于PC容易和個(gè)人計(jì)算機(jī)(Personal Computer)混淆,故人們?nèi)粤?xí)慣地用PLC作為可編程序控制器的縮寫。它是一個(gè)以微處理器為核心的數(shù)字運(yùn)算操作的電子系統(tǒng)裝置,專為在工業(yè)現(xiàn)場(chǎng)應(yīng)用而設(shè)計(jì),它采用可編程序的存儲(chǔ)器,用以在其內(nèi)部存儲(chǔ)執(zhí)行邏輯運(yùn)算、順序控制、定時(shí)/計(jì)數(shù)和算術(shù)運(yùn)算等操作指令,并通過數(shù)字式或模擬式的輸入、輸出接口,控制各種類型的機(jī)械或生產(chǎn)過程。PLC是微機(jī)技術(shù)與傳統(tǒng)的繼電接觸控制技術(shù)相結(jié)合的產(chǎn)物,它克服了繼電接觸控制系統(tǒng)中的機(jī)械觸點(diǎn)的接線復(fù)雜、可靠性低、功耗高、通用性和靈活性差的缺點(diǎn),充分利用了微處理器的優(yōu)點(diǎn),又照顧到現(xiàn)場(chǎng)電氣操作維修人員的技能與習(xí)慣,特別是PLC的程序編制,不需要專門的計(jì)算機(jī)編程語言知識(shí),而是采用了一套以繼電器梯形圖為基礎(chǔ)的簡(jiǎn)單指令形式,使用戶程序編制形象、直觀、方便易學(xué);調(diào)試與查錯(cuò)也都很方便。用戶在購(gòu)到所需的PLC后,只需按說明書的提示,做少量的接線和簡(jiǎn)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(shí)踐。

在第三稿中,對(duì)PLC作了如下定義:可編程序控制器是一種數(shù)字運(yùn)算操作電子系統(tǒng),專為在工業(yè)環(huán)境下應(yīng)用而設(shè)計(jì)。它采用了可編程序的存儲(chǔ)器,用來在其內(nèi)部存儲(chǔ)執(zhí)行邏輯運(yùn)算、順序控制、定時(shí)、計(jì)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,控制各種類型的機(jī)械或生產(chǎn)過程??删幊绦蚩刂破骷捌溆嘘P(guān)的外圍設(shè)備,都應(yīng)按易于與工業(yè)控制系統(tǒng)形成一個(gè)整體、易于擴(kuò)充其功能的原則設(shè)計(jì)。為適應(yīng)工業(yè)環(huán)境使用,與一般控制裝置相比較,PLC機(jī)有以下特點(diǎn):

④隔離——在微處理器與I/O電路之間,采用光電隔離措施,有效地隔離I/O接口與CPU之間電的聯(lián)系,減少故障和誤動(dòng)作;各I/O口之間亦彼此隔離。

還有一些PLC將整體式和模塊式的特點(diǎn)結(jié)合起來,構(gòu)成所謂疊裝式PLC。疊裝式PLC其CPU、電源、I/O接口等也是各自獨(dú)立的模塊,但它們之間是靠電纜進(jìn)行聯(lián)接,并且各模塊可以一層層地疊裝。這樣,不但系統(tǒng)可以靈活配置,還可做得體積小巧。
