1. 制定設(shè)備運(yùn)行方案
制定方案就是根據(jù)生產(chǎn)工藝的要求，分析各輸入、輸出與各種操作之間的邏輯關(guān)系，確定需要檢測(cè)的量和控制的方法，并設(shè)計(jì)出系統(tǒng)中各設(shè)備的操作內(nèi)容和操作順序。據(jù)此便可畫出流程圖。
2. 畫控制流程圖
對(duì)于較復(fù)雜的應(yīng)用系統(tǒng)，需要繪制系統(tǒng)控制流程圖，用以清楚地表明動(dòng)作的順序和條件。對(duì)于簡(jiǎn)單的控制系統(tǒng)，可省去這一步。
3. 制定系統(tǒng)的抗干擾措施
根據(jù)現(xiàn)場(chǎng)工作環(huán)境、干擾源的性質(zhì)等因素，綜合制定系統(tǒng)的硬件和軟件抗干擾措施，如硬件上的電源隔離、信號(hào)濾波，軟件上的平均值濾波等。
4. 編寫程序
根據(jù)被控對(duì)象的輸入輸出信號(hào)及所選定的PLC型號(hào)分配PLC的硬件資源，為梯形圖的各種繼電器或接點(diǎn)進(jìn)行編號(hào)，再按照軟件規(guī)格說(shuō)明書(技術(shù)要求、編制依據(jù)、測(cè)試)，用梯形圖進(jìn)行編程。
5. 軟件測(cè)試
剛編寫好的程序難免有缺陷或錯(cuò)誤。為了及時(shí)發(fā)現(xiàn)和消除程序中的錯(cuò)誤和缺陷，需要對(duì)程序進(jìn)行離線測(cè)試。經(jīng)調(diào)試、排錯(cuò)、修改及模擬運(yùn)行后，才能正式投入運(yùn)行。
6. 編制程序使用說(shuō)明書
當(dāng)一項(xiàng)軟件工程完成后，為了便于用戶和現(xiàn)場(chǎng)調(diào)試人員的使用，應(yīng)對(duì)所編制的程序進(jìn)行說(shuō)明，說(shuō)明書應(yīng)包括程序設(shè)計(jì)的依據(jù)、結(jié)構(gòu)、功能、流程圖，各項(xiàng)功能單元的分析，PLC的IO信號(hào)，軟件程序操作使用的步驟、注意事項(xiàng)等。
PLC應(yīng)用系統(tǒng)設(shè)計(jì)實(shí)例
機(jī)械手控制系統(tǒng)設(shè)計(jì)
1. 工藝過(guò)程及控制要求
1) 工藝過(guò)程
圖6.1所示為一簡(jiǎn)易物料搬運(yùn)機(jī)械手的工藝流程圖。該機(jī)械手是一個(gè)水平垂直位移的機(jī)械設(shè)備，其操作是將工件從左工作臺(tái)搬運(yùn)到右工作臺(tái)，由光耦合器VLC來(lái)檢測(cè)工作臺(tái)上有沒有工件。機(jī)械手通常位于原點(diǎn)，它的動(dòng)作全部由氣缸驅(qū)動(dòng)，而氣缸則由相應(yīng)的電磁閥控制。其中，上升下降和左移右移分別由雙線圈二位電磁閥控制，放松夾緊由一個(gè)單線圈二位電磁閥(稱為夾緊電磁閥)控制。
2) 控制要求
機(jī)械手整個(gè)搬運(yùn)過(guò)程要求都能自動(dòng)控制。在啟動(dòng)過(guò)程中能切換到手動(dòng)控制及自動(dòng)控制或半自動(dòng)控制(又稱單周期控制)，以便對(duì)設(shè)備進(jìn)行調(diào)整和檢修。圖6.2是機(jī)械手控制系統(tǒng)的邏輯流程圖。系統(tǒng)啟動(dòng)之前，機(jī)械手處于原始位置，條件是機(jī)械手在高位﹑左位。
