PLC的工作電源有120/230V單相交流電源和24V直流電源。系統(tǒng)的大多數(shù)干擾往往通過電源進(jìn)入PLC,在干擾強(qiáng)或可靠性要求高的場合,動(dòng)力部分、控制部分、PLC自身電源及I/O回路的電源應(yīng)分開配線,用帶屏蔽層的隔離變壓器給PLC供電。隔離變壓器的一次側(cè)最好接380V,這樣可以避免接地電流的干擾。輸入用的外接直流電源最好采用穩(wěn)壓電源,因?yàn)檎鳛V波電源有較大的波紋,容易引起誤動(dòng)作。
瞬時(shí)過電流保護(hù)。由于逆變器負(fù)載側(cè)短路等,流過逆變器器件的電流達(dá)到異常值(超過容許值)時(shí),瞬時(shí)停止逆變器運(yùn)轉(zhuǎn),切斷電流。變流器的輸出電流達(dá)到異常值,也同樣停止逆變器運(yùn)轉(zhuǎn)。
PLC采用循環(huán)掃描的工作方式,在PLC中用戶程序按先后順序存放,CPU從第一條指令開始執(zhí)行程序,直到遇到結(jié)束符后又返回第一條,如此周而復(fù)始不斷循環(huán)。PLC的掃描過程分為內(nèi)部處理、通信操作、程序輸入處理、程序執(zhí)行、程序輸出幾個(gè)階段。全過程掃描一次所需的時(shí)間稱為掃描周期。當(dāng)PLC處于停狀態(tài)時(shí),只進(jìn)行內(nèi)部處理和通信操作服務(wù)等內(nèi)容。在PLC處于運(yùn)行狀態(tài)時(shí),從內(nèi)部處理、通信操作、程序輸入、程序執(zhí)行、程序輸出,一直循環(huán)掃描工作。
近幾年來,可編程序控制器(PLC)以其可靠性高、適應(yīng)性強(qiáng)、靈活性好、編程簡單、容易掌握等特性,在各個(gè)領(lǐng)域發(fā)揮越來越重要的作用。在PLC控制系統(tǒng)中,PLC作為主要控制設(shè)備,必然與控制對象中各種輸入信號(如按鈕、限位開關(guān)、拔動(dòng)開關(guān)、繼電器的觸點(diǎn)及其它檢測信號等)和輸出設(shè)備(如繼電器線圈、接觸器線圈、電磁閥等執(zhí)行元件)相關(guān)聯(lián)。在實(shí)際工作中,由于受PLC應(yīng)用系統(tǒng)規(guī)模的限制,PLC輸入/輸出點(diǎn)數(shù)往往不夠用。為此若采用擴(kuò)展輸入/輸出單元或更換點(diǎn)數(shù)更多的PLC來解決有時(shí)又不合算,為了降低系統(tǒng)硬件的成本,常常采用各種技巧減少系統(tǒng)占用的輸入/輸出點(diǎn)數(shù),相當(dāng)于擴(kuò)展了PLC的I/O點(diǎn)數(shù)。本文從硬件、軟件兩個(gè)方面介紹在不增加硬件情況下"擴(kuò)展"PLC I/O點(diǎn)數(shù)的幾種方法。

交流回路中的電容器投入電網(wǎng)或從電網(wǎng)中切除時(shí),接觸器選擇應(yīng)考慮電容器的合閘沖擊電流。一般地,接觸器的額定電流可按電容器的額定電流的1.5倍選取,型號選CJ10、CJ20等。
變頻器驅(qū)動(dòng)電路、保護(hù)信號檢測及處理電路、脈沖發(fā)生及信號處理電路等控制電路稱為輔助電路。輔助電路發(fā)生故障后,其故障原因較為復(fù)雜,除固化程序丟失或集成塊損壞(這類故障處理方法一般只能采用控制板整塊更換或集成塊更換)外,其他故障較易判斷和處理。
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(shí)也較安全。但為了方便和減少設(shè)備,常按實(shí)際電網(wǎng)電壓選取。
