1、PLC是建立在單片機(jī)之上的產(chǎn)品,單片機(jī)是一種集成電路,兩者不具有可比性;
2、PLC更加適合于工業(yè)惡劣環(huán)境下使用使用比較穩(wěn)定而單片機(jī)的工作環(huán)境要高一些;
3、在程序語言上單片機(jī)多采用匯編語言,PLC采用梯形圖語言;
4、單片機(jī)可以構(gòu)成各種各樣的應(yīng)用系統(tǒng),從微型、小型到中型、大型都可,PLC是單片機(jī)應(yīng)用系統(tǒng)的一個特例;
5、不同廠家的PLC有相同的工作原理,類似的功能和指標(biāo),有一定的互換性,質(zhì)量有保證,編程軟件正朝標(biāo)準(zhǔn)化方向邁進(jìn)。這正是PLC獲得廣泛應(yīng)用的基礎(chǔ)。而單片機(jī)應(yīng)用系統(tǒng)則是八仙過海,各顯神通,功能千差萬別,質(zhì)量參差不齊,學(xué)習(xí)、使用和維護(hù)都很困難。
zui后,從工程的角度,談?wù)凱LC與單片機(jī)系統(tǒng)的選用:
1.對單項(xiàng)工程或重復(fù)數(shù)極少的項(xiàng)目,采用PLC方案是明智、快捷的途徑,成功率高,可塑性好,手尾少,但成本較高。
2.對于量大的配套項(xiàng)目,采用單片機(jī)系統(tǒng)具有成本低、效益高的優(yōu)點(diǎn),但這要有相當(dāng)?shù)难邪l(fā)力量和行業(yè)經(jīng)驗(yàn)才能使系統(tǒng)穩(wěn)定、可接地運(yùn)行。的方法是單片機(jī)系統(tǒng)嵌入PLC的功能,這樣可大大簡化單片機(jī)系統(tǒng)的研制時(shí)間,性能得到保障,效益也就有保證。
