）分析被控對(duì)象并提出控制要求
詳細(xì)分析被控對(duì)象的工藝過(guò)程及工作特點(diǎn)，了解被控對(duì)象機(jī)、電、液之間的配合，提出被控對(duì)象對(duì)PLC控制系統(tǒng)的控制要求，確定控制方案，擬定設(shè)計(jì)任務(wù)書(shū)。
（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(kāi)關(guān)、轉(zhuǎn)換開(kāi)關(guān)及各種傳感器等）和輸出設(shè)備（如：接觸器、電磁閥、信號(hào)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(diǎn)數(shù)。
（三）選擇PLC
PLC選擇包括對(duì)PLC的機(jī)型、容量、I/O模塊、電源等的選擇，詳見(jiàn)本章第二節(jié)。
（四）分配I/O點(diǎn)并設(shè)計(jì)PLC外圍硬件線(xiàn)路
1.分配I/O點(diǎn)
畫(huà)出PLC的I/O點(diǎn)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(jì)PLC外圍硬件線(xiàn)路
畫(huà)出系統(tǒng)其它部分的電氣線(xiàn)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(xiàn)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(xiàn)路已經(jīng)確定。
