　PLC(ProgrammableLogicController)可編程邏輯控制器是20世紀(jì)60年代末期逐步發(fā)展起來的一種以計算機(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)計的數(shù)字運算操作的電子裝置。它采用可以編制程序的存儲器，用來在其內(nèi)部存儲執(zhí)行邏輯運算、順序運算、計時、計數(shù)和算術(shù)運算等操作的指令，并能通過數(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)形成一個整體，易于擴(kuò)展其功能的原則而設(shè)計。
　　一種特殊的R&B吹塑機(jī)器有9根伺服液壓驅(qū)動軸——3根用來控制型坯(把材料擠壓成空心管或半球體，這是吹塑工藝的第一步)，6根用來控制運動。這種機(jī)器包含2個梭子，2個模具，以及2根吹管。運轉(zhuǎn)時，夾具反復(fù)打開和夾緊模具，吹管反復(fù)做上下運動，傳送裝置帶動夾具至型坯正下方，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)升級項目。Chin說：“R&B使用了標(biāo)準(zhǔn)的SiemensSimaticS7PLC來控制這些位置運動。我們提供了一套功能模塊，使R&B能運用PLC進(jìn)行位置控制。其它的機(jī)器可能要使用運動控制器來控制運動，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)到與獨立控制器相同的功能和性能?！?br /> 　　Chin說：“PLC通常很難做到高精度的伺服控制，這是專用運動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)了運動控制功能，它通過液壓驅(qū)動裝置對各個部件進(jìn)行定位?！?br /> 　　PLC還對30多個區(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個區(qū)域既能加熱又能冷卻，另外18個只能加熱。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隙穫鱽淼睦渌芰霞訜岬?15°F。
　　常規(guī)PLC采用IEC-61131標(biāo)準(zhǔn)語言編寫的功能模塊控制所有的伺服液壓系統(tǒng)驅(qū)動軸。它不需要特殊的運動控制環(huán)境。加入運動控制功能的PLC相對于專用PLC和獨立的運動控制器而言，具有更出色的性能和更高效的處理能力。
