PLC使用半導(dǎo)體集成電路作定時器,時基脈沖由晶體振蕩器產(chǎn)生,精度相當高,定時范圍一般從0.1 s到若干分鐘甚至更長,用戶可根據(jù)需要在程序中設(shè)定定時值,然后由軟件和硬件計數(shù)器來控制定時時間,定時精度小于10 ms且定時時間不受環(huán)境的影響。
根據(jù)機床設(shè)備的接線圖就可以進行機床電氣設(shè)備的安裝接線。對某些較為復(fù)雜的電氣設(shè)備,電氣安裝板上元件較多時,還可畫出安裝板的接線圖。對于簡單設(shè)備,僅畫出接線圖就可以了。實際工作中,接線圖常與電氣原理圖結(jié)合起來使用
在所有指令執(zhí)行完畢后,將各物理繼電器對應(yīng)的輸出狀態(tài)寄存器的通 / 斷狀態(tài),在輸出刷新階段轉(zhuǎn)存到輸出寄存器,去控制各物理繼電器的通 / 斷,這才是 PLC 的實際輸出。

編程器是 PLC 很重要的外部設(shè)備,它主要由鍵盤、顯示器組成。編程器分簡易型和智能型兩類。小型 PLC 常用簡易編程器,大、中型 PLC 多用智能編程器。編程器的作用是編制用戶程序并送入 PLC 程序存儲器。利用編程器可檢查、修改、調(diào)試用戶程序和在線監(jiān)視 PLC 工作狀況。
接觸器的線圈電壓,一般應(yīng)低一些為好,這樣對接觸器的絕緣要求可以降低,使用時也較安全。但為了方便和減少設(shè)備,常按實際電網(wǎng)電壓選取。

PLC是一種在工業(yè)中被廣泛應(yīng)用的自動控制元件。然而PLC應(yīng)用與編程人才短缺已經(jīng)成為制約我國自動控制領(lǐng)域發(fā)展的瓶頸。通過學(xué)習(xí)PLC可編程控制器程序設(shè)計使學(xué)員掌握可編程序控制器的工作原理和PLC控制系統(tǒng)硬件軟件的設(shè)計方法,可編寫復(fù)雜的PLC程序,為從事PLC控制系統(tǒng)的設(shè)計、調(diào)試和改造工作打下基礎(chǔ)??梢元毩⒊袚嚓P(guān)項目的設(shè)計與開發(fā)。讓您由一位電工升級為貨真價實的工程師!
對PLC本體按照規(guī)定的標準和接地條件進行接地。此時,應(yīng)避免和變頻器使用共同的接地線,并在接地時盡可能使二者分開。當電源條件不太好時,應(yīng)在PLC的電源模塊以及輸入/輸出模塊的電源線上接入噪聲濾波器和降低噪音用的變壓器等。此外,如有必要在變頻器一側(cè)也應(yīng)采取相應(yīng)措施。
