WL36-B23現(xiàn)貨
唐僧:徒兒們,這佛祖交待的DCS、PLC、數(shù)控系統(tǒng)要哪里買?誰(shuí)是正規(guī)的?
孫悟空:師傅,我用火眼金睛照過(guò)了,《福州聚福興自動(dòng)化有限公司》是正規(guī)的!他們開(kāi)在《福州倉(cāng)山》,這地方專做進(jìn)出口的,假不了!
唐僧:那產(chǎn)品怎么樣,值得信賴嗎?他們主要是做什么品牌的?
孫悟空:師傅,您放心這家的產(chǎn)品都是《的,無(wú)假貨》,而且《服務(wù)態(tài)度好,是個(gè)負(fù)責(zé)任的公司》,至于他們做得產(chǎn)品有......(此省略10000字),總之一句話:《只要有的品牌,他們都做》。
豬八戒:那價(jià)格怎么樣,可以留點(diǎn)錢買吃的嗎?
孫悟空:八戒你就知道吃,不過(guò)他們的《價(jià)格是同行里非常好》的!
沙悟凈:那要我去挑嗎?
孫悟空:不用,一般他們是《包郵》的!
唐僧:那還等什么,快去買,買完完成任務(wù)我就升官了。
用PLC實(shí)現(xiàn)對(duì)系統(tǒng)的控制是非常方便的。這是因?yàn)椋菏紫萈LC控制邏輯的建立是程序,用程序代替硬件接線。編程序比接線,更改程序比更改接線,當(dāng)然要方便得多!
其次PLC的硬件是高度集成化的,已集成為種種小型化的模塊。而且,這些模塊是配套的,已實(shí)現(xiàn)了系列化與規(guī)格化。種種控制系統(tǒng)所需的模塊,PLC廠家多有現(xiàn)貨供應(yīng),市場(chǎng)上即可購(gòu)得。所以,硬件系統(tǒng)配置與建造也非常方便。
正因如此,用可編程序控制器才有這個(gè)"可"字。對(duì)軟件講,它的程序可編,也不難編。對(duì)硬件講,它的配置可變,而且也易于變。
具體地講,PLC有五個(gè)方面的方便:
(1)配置方便:可接控制系統(tǒng)的需要確定要使用哪家的PLC,那種類型的,用什么模塊,要多少模塊,確定后,到市場(chǎng)上定貨購(gòu)買即可。
(2)安裝方便:PLC硬件安裝簡(jiǎn)單,組裝容易。外部接線有接線器,接線簡(jiǎn)單,而且一次接好后,更換模塊時(shí),把接線器安裝到新模塊上即可,都不必再接線。內(nèi)部什么線都不要接,只要作些必要的DIP開(kāi)關(guān)設(shè)定或軟件設(shè)定,以及編制好用戶程序就可工作。
編程方便:PLC內(nèi)部雖然沒(méi)有什么實(shí)際的繼電器、時(shí)間繼電器、計(jì)數(shù)器,但它通過(guò)程序(軟件)與系統(tǒng)內(nèi)存,這些器件卻實(shí)實(shí)在在地存在著。其數(shù)量之多是繼電器控制系統(tǒng)難以想象的。即使是小型的PLC,內(nèi)部繼電器數(shù)都可以千計(jì),時(shí)間繼電器、計(jì)數(shù)也以百計(jì)。而且,這些繼電器的接點(diǎn)可次地使用。PLC內(nèi)部邏輯器件之多,用戶用起來(lái)已不感到有什么限制??紤]的只是入出點(diǎn)。而這個(gè)內(nèi)部入出點(diǎn)即使用得再多,也無(wú)關(guān)緊要。大型PLC的控制點(diǎn)數(shù)可達(dá)萬(wàn)點(diǎn)以上,哪有那么大的現(xiàn)實(shí)系統(tǒng)若實(shí)在不夠,還可聯(lián)網(wǎng)進(jìn)行控制,不受什么限制。PLC的指令系統(tǒng)也非常豐富,可毫不困難地實(shí)現(xiàn)種種開(kāi)關(guān)量,以及模擬量的控制。PLC還有存儲(chǔ)數(shù)據(jù)的內(nèi)存區(qū),可存儲(chǔ)控制過(guò)程的所有要保存的信息?!傊?,由于PLC功能之強(qiáng),發(fā)揮其在控制系統(tǒng)的作用,所受的限制已不是PLC本身,而是人們的想象力,或與其配套的其它硬件設(shè)施了。
PLC的外設(shè)很豐富,編程器種類很多,用起來(lái)都較方便,還有數(shù)據(jù)監(jiān)控器,可監(jiān)控PLC的工作。使用PLC的軟件也很多,不僅可用類似于繼電電路設(shè)計(jì)的梯形圖語(yǔ)言,有的還可用BASIC語(yǔ)言、C語(yǔ)言,以至于自然語(yǔ)言。這些也為PLC編程提供了方便。
