從PLC的組成來看,除CPU,存儲(chǔ)器及通信接口外,與工業(yè)現(xiàn)場直接有關(guān)的還有哪些接口?并說明其主要功能。
(1)輸入接口:接受被控設(shè)備的信號,并通過光電耦合器件和輸入電路驅(qū)動(dòng)內(nèi)部電路接通或斷開。
(2)輸出接口:程序的執(zhí)行結(jié)果通過輸出接口的光電耦合器件和輸出組件(繼電器、 晶閘管、晶體管)輸出,控制外部負(fù)載的接通或斷開。
2、PLC的基本單元由哪幾個(gè)部份組成?各起什么作用?
(1)CPU :PLC的核心部件,指揮PLC進(jìn)行各種工作。如接受用戶程序和數(shù) 據(jù)、診斷、執(zhí)行執(zhí)行程序等;
(2)存儲(chǔ)器:存儲(chǔ)系統(tǒng)和用戶的程序和數(shù)據(jù);
(3)I / O接口:PLC與工業(yè)生產(chǎn)現(xiàn)場被控對象之間的連接部件,用來接受被控設(shè) 備的信號和輸出程序的執(zhí)行結(jié)果;
(4)通信接口:通過通信接口與監(jiān)視器、打印機(jī)等其他設(shè)備進(jìn)行信息交換;
(5)電源。
