工業(yè)4.0時(shí)代,企業(yè)數(shù)字化轉(zhuǎn)型與智能制造成大勢(shì),自動(dòng)化水平的日益提高,工業(yè)互聯(lián)網(wǎng)的迅速發(fā)展交織著IT(信息技術(shù))、OT(運(yùn)營(yíng)技術(shù))與CT(通訊技術(shù))三條主線的加速融合。可編程邏輯控制器(PLC)作為OT以及工業(yè)自動(dòng)化關(guān)鍵設(shè)備以及工業(yè)互聯(lián)網(wǎng)底層的重要組件,也隨之得到了巨大的進(jìn)步。同時(shí),由于設(shè)備、機(jī)器和工廠變得“更智能”,工業(yè)現(xiàn)場(chǎng)控制對(duì)PLC以及DCS等設(shè)備提出了更高的要求。
智造“先行兵”,PLC助力工業(yè)控制實(shí)現(xiàn)自動(dòng)化
眾所知周,PLC 是在傳統(tǒng)的順序控制器的基礎(chǔ)上引入了微電子技術(shù)、計(jì)算機(jī)技術(shù)、自動(dòng)控制技術(shù)和通訊技術(shù)而形成的新一代工業(yè)控制裝置,目的是用來(lái)取代繼電器、執(zhí)行邏輯、計(jì)時(shí)計(jì)數(shù)等順序控制功能,建立柔性的編程控制系統(tǒng)。目前,PLC 在傳統(tǒng)功能的基礎(chǔ)上增加了模擬量運(yùn)算、PID 功能、通信功能以及更可靠的工業(yè)抗干擾技術(shù)等功能,廣泛應(yīng)用于工業(yè)生產(chǎn)的各個(gè)領(lǐng)域。
因此PLC可簡(jiǎn)單理解為一種用于特定工業(yè)環(huán)境下的計(jì)算機(jī),并具備多種優(yōu)良性能,其硬件結(jié)構(gòu)與計(jì)算機(jī)基本相同,具備CPU、I/O 模塊、電源模塊、底板、外設(shè)以及通信聯(lián)網(wǎng)設(shè)備,采用了可編程的存儲(chǔ)器對(duì)邏輯運(yùn)算、順序控制、計(jì)時(shí)計(jì)數(shù)和算數(shù)運(yùn)算進(jìn)行存儲(chǔ),并通過(guò)數(shù)字的、模擬的輸入輸出指令控制各種類(lèi)型的工業(yè)生產(chǎn)過(guò)程。與通用的計(jì)算機(jī)相比,PLC 在工業(yè)領(lǐng)域的使用場(chǎng)景多、適應(yīng)面廣,并具備可靠性高、抗干擾能力強(qiáng)和編程簡(jiǎn)單等優(yōu)點(diǎn)。
