　PLC(ProgrammableLogicController)可編程邏輯控制器是20世紀(jì)60年代末期逐步發(fā)展起來(lái)的一種以計(jì)算機(jī)技術(shù)為基礎(chǔ)的新型工業(yè)控制裝置。PLC是一種專門為在工業(yè)環(huán)境下應(yīng)用而設(shè)計(jì)的數(shù)字運(yùn)算操作的電子裝置。它采用可以編制程序的存儲(chǔ)器，用來(lái)在其內(nèi)部存儲(chǔ)執(zhí)行邏輯運(yùn)算、順序運(yùn)算、計(jì)時(shí)、計(jì)數(shù)和算術(shù)運(yùn)算等操作的指令，并能通過(guò)數(shù)字式或模擬式的輸入和輸出，控制各種類型的機(jī)械或生產(chǎn)過(guò)程。PLC及其有關(guān)的外圍設(shè)備都應(yīng)該按易于與工業(yè)控制系統(tǒng)形成一個(gè)整體，易于擴(kuò)展其功能的原則而設(shè)計(jì)。
　　一種特殊的R&B吹塑機(jī)器有9根伺服液壓驅(qū)動(dòng)軸——3根用來(lái)控制型坯(把材料擠壓成空心管或半球體，這是吹塑工藝的第一步)，6根用來(lái)控制運(yùn)動(dòng)。這種機(jī)器包含2個(gè)梭子，2個(gè)模具，以及2根吹管。運(yùn)轉(zhuǎn)時(shí)，夾具反復(fù)打開(kāi)和夾緊模具，吹管反復(fù)做上下運(yùn)動(dòng)，傳送裝置帶動(dòng)夾具至型坯正下方，到達(dá)吹氣位置。
　　DavidChin是NDCTechnologies的技術(shù)人員，該公司是Siemens的戰(zhàn)略合作伙伴，一同參與了R&B控制系統(tǒng)升級(jí)項(xiàng)目。Chin說(shuō)：“R&B使用了標(biāo)準(zhǔn)的SiemensSimaticS7PLC來(lái)控制這些位置運(yùn)動(dòng)。我們提供了一套功能模塊，使R&B能運(yùn)用PLC進(jìn)行位置控制。其它的機(jī)器可能要使用運(yùn)動(dòng)控制器來(lái)控制運(yùn)動(dòng)，這是一種專用于伺服控制和定位的控制器。我們定制的功能模塊能夠達(dá)到與獨(dú)立控制器相同的功能和性能?！?br /> 　　Chin說(shuō)：“PLC通常很難做到高精度的伺服控制，這是專用運(yùn)動(dòng)控制器被廣泛采用的原因。但是在我們的應(yīng)用中，標(biāo)準(zhǔn)的SiemensS-7PLC承擔(dān)了運(yùn)動(dòng)控制功能，它通過(guò)液壓驅(qū)動(dòng)裝置對(duì)各個(gè)部件進(jìn)行定位?！?br /> 　　PLC還對(duì)30多個(gè)區(qū)域進(jìn)行溫度控制，這些區(qū)域包括加料斗、擠出機(jī)以及型坯頂部。其中12個(gè)區(qū)域既能加熱又能冷卻，另外18個(gè)只能加熱。溫控系統(tǒng)必須將機(jī)器各部分的溫度誤差范圍控制在1度以內(nèi)。型坯頂部要能夠?qū)⒘隙穫鱽?lái)的冷塑料加熱到415°F。
　　常規(guī)PLC采用IEC-61131標(biāo)準(zhǔn)語(yǔ)言編寫(xiě)的功能模塊控制所有的伺服液壓系統(tǒng)驅(qū)動(dòng)軸。它不需要特殊的運(yùn)動(dòng)控制環(huán)境。加入運(yùn)動(dòng)控制功能的PLC相對(duì)于專用PLC和獨(dú)立的運(yùn)動(dòng)控制器而言，具有更出色的性能和更高效的處理能力。
