他們認(rèn)為,未來嵌入式技術(shù)將會被廣泛應(yīng)用于PAC,成為自動化系統(tǒng)的重要技術(shù)之一。
在用戶和系統(tǒng)集成商之間,對于PAC的質(zhì)疑同樣存在:PAC相對于PLC來說價格高、可靠性低、可拓展能力差,還有人認(rèn)為,PAC并沒有真正針對某種迫切的或者潛在的市場需求,因此不免曲高和寡。
有部分反對者則認(rèn)為,PAC技術(shù)發(fā)展趨向,如統(tǒng)一的多專業(yè)開發(fā)平臺、通信技術(shù)等也會對PLC的技術(shù)發(fā)展施加有益的影響。
值得一提的是,除了上述提到的PLC、PC-Based和PAC之外,針對行業(yè)應(yīng)用,機(jī)器人專用控制器成為國內(nèi)多數(shù)廠商布局的重點(diǎn),特別是像埃斯頓、華中數(shù)控、配天機(jī)器人等這樣以機(jī)器人本體研發(fā)為主的企業(yè)。
目前,隨著大規(guī)模和超大規(guī)模集成電路等微電子技術(shù)的發(fā)展,PLC已由初一位機(jī)發(fā)展到現(xiàn)在的以16位和32位微處理器構(gòu)成的微機(jī)化PC,而且實(shí)現(xiàn)了多處理器的多通道處理。如今,PLC技術(shù)已非常成熟,不僅控制功能增強(qiáng),功耗和體積減小,成本下降,可靠性提高,編程和故障檢測更為靈活方便,而且隨著遠(yuǎn)程I/O和通信網(wǎng)絡(luò)、數(shù)據(jù)處理以及圖象顯示的發(fā)展,使PLC向用于連續(xù)生產(chǎn)過程控制的方向發(fā)展,成為實(shí)現(xiàn)工業(yè)生產(chǎn)自動化的一大支柱。如今在各個行業(yè)的智能制造時代,PLC技術(shù)的發(fā)展呈現(xiàn)出產(chǎn)品規(guī)模兩極發(fā)展、通信網(wǎng)絡(luò)化、模塊化與智能化、編程語言/工具的多樣化和標(biāo)準(zhǔn)化等新的特點(diǎn),并與新興技術(shù)結(jié)合,將進(jìn)一步賦能數(shù)字化企業(yè)和智能工廠。
