用PLC實現對系統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,已實現了系列化與規格化。種種控制系統所需的模塊,PLC廠家多有現貨供應,市場上即可購得。所以,硬件系統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。內部什么線都不要接,只要作些必要的DIP開關設定或軟件設定,以及編制好用戶程序就可工作。
(3)編程方便:PLC內部雖然沒有什么實際的繼電器、時間繼電器、計數器,但它通過程序(軟件)與系統內存,這些器件卻實實在在地存在著。其數量之多是繼電器控制系統難以想象的。即使是小型的PLC,內部繼電器數都可以千計,時間繼電器、計數也以百計。而且,這些繼電器的接點可無限次地使用。PLC內部邏輯器件之多,用戶用起來已不感到有什么限制。唯一考慮的只是入出點。而這個內部入出點即使用得再多,也無關緊要。大型PLC的控制點數可達萬點以上,哪有那么大的現實系統?若實在不夠,還可聯網進行控制,不受什么限制。PLC的指令系統也非常豐富,可毫不困難地實現種種開關量,以及模擬量的控制。PLC還有存儲數據的內存區,可存儲控制過程的所有要保存的信息!傊,由于PLC功能之強,發揮其在控制系統的作用,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施了。
PLC的外設很豐富,編程器種類很多,用起來都較方便,還有數據監控器,可監控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。某定型產品用的PLC的程序完善之后,凡這種產品都可使用。生產一臺,拷貝一份即可。這比起繼電器電路臺臺設備都要接線、調試,要省事及簡單得多。
