(一)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)。
?。ǘ┐_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)。
?。ㄈ┻x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外圍硬件線路
1.分配I/O點(diǎn)
