PLC應(yīng)用系統(tǒng)設(shè)計(jì)的內(nèi)容和步驟
系統(tǒng)設(shè)計(jì)的原則與內(nèi)容
1．設(shè)計(jì)原則
(1) 大限度地滿足被控設(shè)備或生產(chǎn)過(guò)程的控制要求；
(2) 在滿足控制要求的前提下，力求簡(jiǎn)單、經(jīng)濟(jì)，操作方便；
(3) 保證控制系統(tǒng)工作安全可靠；
(4) 考慮到今后的發(fā)展改進(jìn)，應(yīng)適當(dāng)留有進(jìn)一步擴(kuò)展的余地。
2．設(shè)計(jì)內(nèi)容
(1) 擬定控制系統(tǒng)設(shè)計(jì)的技術(shù)條件，它是整個(gè)設(shè)計(jì)的依據(jù)；
(2) 選擇電氣傳動(dòng)形式和電動(dòng)機(jī)、電磁閥等執(zhí)行機(jī)構(gòu)；
(3) 選定PLC的型號(hào)；
(4) 編制PLC的輸入輸出分配表或繪制輸入輸出端子接線圖；
(5) 根據(jù)系統(tǒng)要求編寫(xiě)軟件說(shuō)明書(shū)，然后再進(jìn)行程序設(shè)計(jì)；
(6) 重視人機(jī)界面的設(shè)計(jì)，增強(qiáng)人與機(jī)器之間的友善關(guān)系；
(7) 設(shè)計(jì)操作臺(tái)、電氣柜及非標(biāo)準(zhǔn)電器元部件；
(8) 編寫(xiě)設(shè)計(jì)說(shuō)明書(shū)和使用說(shuō)明書(shū)。
系統(tǒng)設(shè)計(jì)和調(diào)試的主要步驟
1．深入了解和分析被控對(duì)象的工藝條件和控制要求
2．確定IO設(shè)備，常用的輸入設(shè)備有按鈕、選擇開(kāi)關(guān)、行程開(kāi)關(guān)、傳感器等，常用的輸出設(shè)備有繼電器、接觸器、指示燈、電磁閥等。
3．選擇合適的PLC類型， 根據(jù)已確定的用戶IO設(shè)備，統(tǒng)計(jì)所需的輸入信號(hào)和輸出信號(hào)的點(diǎn)數(shù)，選擇合適的PLC類型。
