（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)。
（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P
產(chǎn)品質(zhì)量決定企業(yè)的未來(lái)，我們不生產(chǎn)PLC，我們只是*的搬運(yùn)工.

PLC采用兩套美國(guó)AB公司的ControlLogix系列PLC構(gòu)成硬冗余系統(tǒng)。通過(guò)主PLC上的1756-CNBR模塊連接到一個(gè)冗余的控制網(wǎng)網(wǎng)絡(luò)上，與安裝在儲(chǔ)送料操作箱里的Flex遠(yuǎn)程I/O站實(shí)現(xiàn)實(shí)時(shí)高效通訊，冗余介質(zhì)的采用避免了通訊電纜損壞時(shí)的系統(tǒng)崩潰。
為了避免市電突然停電造成系統(tǒng)數(shù)據(jù)丟失而采用了山特的UPS，實(shí)現(xiàn)不間斷供
ControlLogix處理器是32位總線的控制器，控制能力非常強(qiáng)，可達(dá)數(shù)字量128，000個(gè)、模擬量I/O 4000個(gè)，程序掃描時(shí)間/K指令為0.08ms（布爾型），本系統(tǒng)處理器可以使用的內(nèi)存容量達(dá)到2M字節(jié)。硬件設(shè)計(jì)上，ControlLogix處理器可以插在機(jī)架中的任何一個(gè)槽內(nèi)，且在同一機(jī)架上可插入多個(gè)處理器，共享公共輸入數(shù)據(jù)，處理器之間的運(yùn)行相互獨(dú)立，處理器不僅可以控制和組態(tài)本地框架內(nèi)的輸入輸出模板，還可以控制和組態(tài)網(wǎng)絡(luò)上任何遠(yuǎn)程框架上的輸入輸出模板。
ControlLogix處理器提供系統(tǒng)時(shí)鐘，具有豐富的指令集包括文件處理、順序器、診斷、移位寄存器、PID控制、繼電器、計(jì)時(shí)器、計(jì)數(shù)器、寄存器、程序控制和運(yùn)動(dòng)控制指令；多重優(yōu)先級(jí)多任務(wù)操作系統(tǒng)支持32個(gè)可組態(tài)的連續(xù)性或周期性任務(wù)，這些任務(wù)根據(jù)具體應(yīng)用程序且按照優(yōu)先級(jí)來(lái)執(zhí)行程序代碼，用戶可以為每一個(gè)任務(wù)分配zui多32個(gè)程序，每個(gè)程序都可以有自己的本地?cái)?shù)據(jù)或梯形圖邏輯，在同一個(gè)處理器內(nèi)還允許虛擬機(jī)獨(dú)立運(yùn)行；可實(shí)現(xiàn)預(yù)定的I/O數(shù)據(jù)傳送；符號(hào)尋址方式允許用戶在不依賴硬件的情況下，通過(guò)在應(yīng)用程序中使用符號(hào)來(lái)標(biāo)識(shí)數(shù)據(jù)；RSlogix5000軟件可提供完整的編程和組態(tài)支持，包括在線診斷、在線監(jiān)視處理器和I/O模板的運(yùn)行和故障狀態(tài)等。
ControlLogix處理器可以通過(guò)多種網(wǎng)絡(luò)進(jìn)行連接，如ControlNet、DH+、EtherNet/IP、DeviceNET或RIO，每個(gè)處理器可以與機(jī)架上的多個(gè)通訊模塊進(jìn)行通訊，而且多個(gè)處理器也可以與同一個(gè)通訊模塊進(jìn)行通訊。處理器還可通過(guò)RS-232-C（DF1協(xié)議）與計(jì)算機(jī)通訊，同時(shí)支持冗余介質(zhì)工作方式。
ControlLogix結(jié)構(gòu)提供了范圍寬廣的輸入和輸出模塊，固態(tài)數(shù)字量I/O模塊覆蓋了從10V到265VAC以及10V到146VDC的范圍，繼電器觸點(diǎn)輸出模塊的范圍從10V到265VAC或從5V到150VDC，模擬量信號(hào)的電壓/電流范圍包括標(biāo)準(zhǔn)的模擬量輸入和輸出以及直接的熱電偶及RTD溫度輸入信號(hào)；所有模塊均是基于生產(chǎn)者/消費(fèi)者的模式，具有內(nèi)置模塊和線路的診斷功能、報(bào)警、數(shù)據(jù)定標(biāo)、電子式熔斷、時(shí)間標(biāo)記、電子模塊識(shí)別、模塊級(jí)故障報(bào)告和現(xiàn)場(chǎng)診斷、可選的直接連接或優(yōu)化機(jī)架連接、帶電插拔、可拆卸接線端子塊等特點(diǎn)。
