在80年代至90年代中期,是PLC發(fā)展較快的時(shí)期,年增長(zhǎng)率一直保持為30~40%。由于PLC機(jī)聯(lián)系處理模擬能力和網(wǎng)絡(luò)方面功能的進(jìn)步,擠占了一部分DCS的市場(chǎng)(過程控制)并逐漸壟斷了污水處理等行業(yè),但是由于工業(yè)PC(IPC)的出現(xiàn),特別是現(xiàn)場(chǎng)總線技術(shù)的發(fā)展,IPC和FCS也擠占了一部分PLC市場(chǎng),所以PLC增長(zhǎng)速度,總的說是漸緩。全世界有200多廠家生產(chǎn)300多品種PLC產(chǎn)品,主要應(yīng)用在汽車(23%
5.外部的電磁感應(yīng)干擾 如果變頻器周圍存在干擾源,它們將通過輻射或電源線侵入變頻器的內(nèi)部,引起控制回路誤動(dòng)作,造成工作不正?;蛲C(jī),嚴(yán)重時(shí)甚至損壞變頻器。減少噪聲干擾的具體方法有:變頻器周圍所有繼電器、接觸器的控制線圈上,加裝防止沖擊電壓的吸收裝置,如RC浪涌吸收器,其接線不能**過20cm;盡量縮短控制回路的配線距離,并使其與主回路分離;變頻器控制回路配線絞合節(jié)距離應(yīng)在15mm以上,與主回路保持
NFDV151-P10 NFDV151-P10 NFDV151-P10 在這一步中,要注意一個(gè)問題,就是應(yīng)該將程序保存在什么地方?PC硬盤?閃存設(shè)備?移動(dòng)硬盤?當(dāng)然這些都不可以,所有這些存儲(chǔ)設(shè)備都可能感染病毒。所以,必須且只能將程序燒制到光盤上。而且還有一個(gè)問題,燒制的程序是哪個(gè)程序?在之前我們已經(jīng)將較終調(diào)試并修改完成的程序下載到PLC中,如果PLC在執(zhí)行該程序時(shí)完全無誤的話,就將該程序上傳到PC
