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(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。……總之，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。 

PLC的外設(shè)很豐富，編程器種類很多，用起來都較方便，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)計的梯形圖語言，有的還可用BASIC語言、C語言，以至于自然語言。這些也為PLC編程提供了方便。 

PLC的程序也便于存儲、移植及再使用。某定型產(chǎn)品用的PLC的程序完善之后，凡這種產(chǎn)品都可使用。生產(chǎn)一臺，拷貝一份即可。這比起繼電器電路臺臺設(shè)備都要接線、調(diào)試，要省事及簡單得多。 

（4）維修方便：這是因為： 

①PLC工作可靠，出現(xiàn)故障的情況不多，這大大減輕了維修的工作量。這在講述PLC的第三個特點時，還將進一步介紹。 

②即使PLC出現(xiàn)故障，維修也很方便。這是因為PLC都設(shè)有很多故障提示信號，如PLC支持內(nèi)存保持?jǐn)?shù)據(jù)的電池電壓不足，相應(yīng)的就有電壓低信號指示。而且，PLC本身還可作故障情況記錄。所以，PLC出了故障，很易診斷。同時，診斷出故障后排故也很簡單。可按模塊排故，而模塊的備件市場可以買到，進行簡單的更換就可以。至于軟件，調(diào)試好后不會出故障，再多只要依據(jù)使用經(jīng)驗進行調(diào)整，使之完善就是了。 

（5）改用方便：PLC用于某設(shè)備，若這個設(shè)備不再使用了，其所用的PLC還可給別的設(shè)備使用，只要改編一下程序，就可辦到。如果原設(shè)備與新設(shè)備差別較大，它的一些模塊還可重用。
