一. 掃描技術(shù)
當(dāng)PLC投入運(yùn)行后,其工作過程一般分為三個(gè)階段,即輸入采樣、用戶程序執(zhí)行和輸出刷新三個(gè)階段。完成上述三個(gè)階段稱作一個(gè)掃描周期。
在整個(gè)運(yùn)行期間,PLC的CPU以一定的掃描速度重復(fù)執(zhí)行上述三個(gè)階段。
(一) 輸入采樣階段 在輸入采樣階段,PLC以掃描方式依次地讀入所有輸入狀態(tài)和數(shù)據(jù),并將它們存入I/O映象區(qū)中的相應(yīng)得單元內(nèi)。
輸入采樣結(jié)束后,轉(zhuǎn)入用戶程序執(zhí)行和輸出刷新階段。在這兩個(gè)階段中,即使輸入狀態(tài)和數(shù)據(jù)發(fā)生變化,I/O映象區(qū)中的相應(yīng)單元的狀態(tài)和數(shù)據(jù)也不會改變。
因此,如果輸入是脈沖信號,則該脈沖信號的寬度必須大于一個(gè)掃描周期,才能保證在任何情況下,該輸入均能被讀入。
可編程控制器是一種數(shù)字運(yùn)算操作的電子系統(tǒng),專門在工業(yè)環(huán)境下應(yīng)用而設(shè)計(jì)。它采用可以編制程序的存儲器,用來在執(zhí)行存儲邏輯運(yùn)算和順序控制 定時(shí) 計(jì)數(shù)和算術(shù)運(yùn)算等操作的指令,并通過數(shù)字或模擬的輸入(I)和輸出(O)接口,控制各種類型的機(jī)械設(shè)備或生產(chǎn)過程
可編程邏輯控制器(PLC)的定義 可編程邏輯控制器簡稱PLC(英文全稱:Programmable Logic Controller)。隨著科學(xué)技術(shù)的發(fā)展,為適應(yīng)多品種,小批量生產(chǎn)的需求而產(chǎn)生發(fā)展起來的一種新型的工業(yè)控制裝置。
1.現(xiàn)場輸入接口電路由光耦合電路和微機(jī)的輸入接口電路,作用是PLC與現(xiàn)場控制的接口界面的輸入通道。
2.現(xiàn)場輸出接口電路由輸出數(shù)據(jù)寄存器 選通電路和中斷請求電路集成,作用PLC通過現(xiàn)場輸出接口電路向現(xiàn)場的執(zhí)行部件輸出相應(yīng)的控制信號。
常用的I/O分類如下:
開關(guān)量:按電壓水平分,有22-VAC 11-VAC 24VDC,按隔離方式分,有繼電器隔離和晶體管隔離。
模擬量:按信號類型分,有電流型(4-2-mA,--2-mA) 電壓型(--1-V,--5V,-1--1-V)等,按精度分,有12bit,14bit,16bit等。除了上述通用IO外,還有特殊IO模塊,如熱電阻 熱電偶 脈沖等模塊。
按I/O點(diǎn)數(shù)確定模塊規(guī)格及數(shù)量,I/O模塊可多可少,但其大數(shù)受CPU所能管理的基本配置的能力,即受大的底板或機(jī)架槽數(shù)限制。
