知道了PLC的工作原理后,理解它的語言就比較容易了。PLC語言最常見的有梯形圖和語句表兩種。其中梯形圖又是最為直觀和好用的。要詳細(xì)了解可以看相關(guān)教材,要強(qiáng)調(diào)的是,雖然原理一樣,基本指令也大同小異,但廠家不同PLC指令符號(hào)會(huì)有所不同,例如,同是上升沿微分,三菱公司的產(chǎn)品用PLS表示,歐姆龍公司卻稱為DIFU,而西門子公司則是│P│。這些具體的區(qū)別就要看各種產(chǎn)品的編程手冊(cè)了
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(jiǎn)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(duì)象中各種輸入信號(hào)(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(cè)信號(hào)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。
可編程控制器的工作過程包括兩部分:自診斷及通信響應(yīng)的固定過程和用戶程序執(zhí)行過程,如圖1所示。PLC在每次執(zhí)行用戶程序之前,都先執(zhí)行故障自診斷程序、復(fù)位、監(jiān)視、定時(shí)等內(nèi)部固定程序,若自診斷正常,繼續(xù)向下掃描,然后PLC檢查是否有與編程器、計(jì)算機(jī)等的通信請(qǐng)求。如果有與計(jì)算機(jī)等的通信請(qǐng)求,則進(jìn)行相應(yīng)處理。當(dāng)PLC處于停止(STOP)狀態(tài)時(shí),只循環(huán)進(jìn)行前兩個(gè)過程。而在PLC處于運(yùn)行(RUN)狀態(tài)時(shí),PLC從內(nèi)部處理、通信操作、輸入掃描、執(zhí)行用戶程序、輸出刷新五個(gè)工作階段循環(huán)工作。每完成一次以上五個(gè)階段所需要的時(shí)間稱為一個(gè)掃描周期。

在更換整流塊時(shí),要求其在與散熱片接觸面上均勻地涂上一層傳熱性能良好的硅導(dǎo)熱膏,再緊固螺絲。如果沒有同型號(hào)整流塊時(shí),可用同容量的其它類型的整流塊替代,其固定螺絲孔,必須重新鉆孔、攻絲,再安裝、接線。例如,一臺(tái)80年代中期西門子生產(chǎn)的變頻器(7.5kVA)整流模塊(橢圓形)擊穿后,因無同類整流塊配件,采用三墾生產(chǎn)的同容量整流塊(矩形)替代后,已運(yùn)行多年,目前仍然能正常使用。
額定電壓指主觸點(diǎn)額定工作電壓,應(yīng)等于負(fù)載的額定電壓。一只接觸器常規(guī)定幾個(gè)額定電壓,同時(shí)列出相應(yīng)的額定電流或控制功率。通常,最大工作電壓即為額定電壓。常用的額定電壓值為220V、380V、660V等。
