描述

用PLC實現(xiàn)對系統(tǒng)的控制是非常方便的。這是因為：首先PLC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)，市場上即可購得。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”可”字。對軟件講，它的程序可編，也不難編。對硬件講，它的配置可變，而且也易于變。
具體地講，PLC有五個方面的方便：
（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，到市場上定貨購買即可。
（2）安裝方便：PLC硬件安裝簡單，組裝容易。外部接線有接線器，接線簡單，而且一次接好后，更換模塊時，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開關(guān)設(shè)定或軟件設(shè)定，以及編制好用戶程序就可工作。
（3）編程方便：PLC內(nèi)部雖然沒有什么實際的繼電器、時間繼電器、計數(shù)器，但它通過程序（軟件）與系統(tǒng)內(nèi)存，這些器件卻實實在在地存在著。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，時間繼電器、計數(shù)也以百計。而且，這些繼電器的接點可無限次地使用。PLC內(nèi)部邏輯器件之多，用戶用起來已不感到有什么限制。唯一考慮的只是入出點。而這個內(nèi)部入出點即使用得再多，也無關(guān)緊要。大型PLC的控制點數(shù)可達萬點以上，哪有那么大的現(xiàn)實系統(tǒng)？若實在不夠，還可聯(lián)網(wǎng)進行控制，不受什么限制。PLC的指令系統(tǒng)也非常豐富，可毫不困難地實現(xiàn)種種開關(guān)量，以及模擬量的控制。PLC還有存儲數(shù)據(jù)的內(nèi)存區(qū)，可存儲控制過程的所有要保存的信息?！傊?，由于PLC功能之強，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。
