一)分析被控對象并提出控制要求
詳細(xì)分析被控對象的工藝過程及工作特點,了解被控對象機(jī)、電、液之間的配合,提出被控對象對PLC控制系統(tǒng)的控制要求,確定控制方案,擬定設(shè)計任務(wù)書。
(二)確定輸入/輸出設(shè)備
根據(jù)系統(tǒng)的控制要求,確定系統(tǒng)所需的全部輸入設(shè)備(如:按紐、位置開關(guān)、轉(zhuǎn)換開關(guān)及各種傳感器等)和輸出設(shè)備(如:接觸器、電磁閥、信號指示燈及其它執(zhí)行器等),從而確定與PLC有關(guān)的輸入/輸出設(shè)備,以確定PLC的I/O點數(shù)。
(三)選擇PLC
PLC選擇包括對PLC的機(jī)型、容量、I/O模塊、電源等的選擇,詳見本章第二節(jié)。
(四)分配I/O點并設(shè)計PLC外圍硬件線路
1.分配I/O點
畫出PLC的I/O點與輸入/輸出設(shè)備的連接圖或?qū)?yīng)關(guān)系表,該部分也可在第2步中進(jìn)行。
2.設(shè)計PLC外圍硬件線路
畫出系統(tǒng)其它部分的電氣線路圖,包括主電路和未進(jìn)入可編程控制器的控制電路等。
由PLC的I/O連接圖和PLC外圍電氣線路圖組成系統(tǒng)的電氣原理圖。到此為止系統(tǒng)的硬件電氣線路已經(jīng)確定。
