描述

6ES7-357-4AH01-OAEO

目前,國內(nèi)用戶選用的可編程控制器(PLC)仍以國外產(chǎn)品為主,造成這種局面的一個重要原因是歐、美、日等發(fā)達工業(yè)國家掌握了高端PLC的核心技術,其硬軟件技術對應用者來說完全是封閉的,使用者只能從應用的角度學習PLC,而不能參與PLC的開發(fā)[1-2]。近年來,IEC61131-3國際標準的頒布和實施為各PLC生產(chǎn)廠家提供了統(tǒng)一的軟件開發(fā)準則,開放的高性能單片機技術的發(fā)展,為硬件開發(fā)提供了有效的物質(zhì)基礎[3]。在這樣的背景下,研制開放的PLC系統(tǒng)無論對于科學研究還是促進PLC行業(yè)的發(fā)展都有積極的現(xiàn)實意義。開放式PLC硬件結(jié)構采用CPU+外圍模塊+接口構成,各個接口都按標準設計,大大提高了PLC的開放性,使其能方便地與大系統(tǒng)連接。編程語言遵循國際標準IEC61131-3,并將基于PC的編程軟件作為PLC首選編程工具。系統(tǒng)硬件部分采用高性能51內(nèi)核處理器STC89C51,其為模塊化設計,采用濾波、隔離電路,以降低成本。主要電路有:微控制器STC89C51RC、開關量輸入電路、繼電器輸出電路、晶體管輸出電路、RS232通信接口電路、電源電路、時鐘復位電路和USB通信接口電路等,PLC硬件系統(tǒng)框圖如圖2所示,軟件采用Borland公司集成開發(fā)軟件C++Builder,通過集成平臺對51內(nèi)核處理器指令集進行解釋、編譯,使梯形圖語言轉(zhuǎn)換為能被51內(nèi)核處理器識別的代碼?!DIUSBD12的固件設計成完全的中斷驅(qū)動,當CPU處理前臺任務時,USB的傳輸可在后臺進行;后臺中斷服務程序和前臺主程序循環(huán)之間的數(shù)據(jù)交換可以通過事件標志和數(shù)據(jù)緩沖區(qū)來實現(xiàn)。當PDIUSBD12從USB收到一個數(shù)據(jù)包,即對CPU產(chǎn)生一個中斷請求,CPU立刻響應中斷。在中斷服務程序中,固件將數(shù)據(jù)包從PDIUSBD12內(nèi)部緩沖區(qū)移到循環(huán)數(shù)據(jù)緩沖區(qū),并將PDIUSBD12的內(nèi)部緩沖區(qū)清零,以便接收新的數(shù)據(jù)包,使CPU可以繼續(xù)執(zhí)行當前的前臺任務直到完成。本文利用PDIUSBD12的端點1進行命令的傳輸和應答,端點1每次接收計算機發(fā)送過來的8B指令,其指令格式如表2所示。例如,接收到十六進制碼5201000300070050,表示讀24C01器件從03字節(jié)開始的7個字節(jié)的數(shù)據(jù)。52H為R的ASCII碼,57H為W的ASCII碼。端點2用于數(shù)據(jù)的傳輸。

選擇深圳長欣,選擇放心,售后無憂大量現(xiàn)貨,當天順豐發(fā)貨!
主營:本特利,英維思,伍德沃德,福克斯波羅、西屋、瑞恩、施耐德莫迪康、ABB、AB、西門子、摩托羅拉、GE發(fā)那科、安川、博世力士樂,ACSO,力士樂等各大品牌的DCS系統(tǒng)配件,機器人系統(tǒng)配件,大型伺服系統(tǒng)備件。

先介紹幾點經(jīng)驗。
1、先通讀一遍“系統(tǒng)手冊”(不管能不能看懂,先了解個大概,以便學習編程時查找);
2、由位控邏輯入手,逐漸增加定時、計數(shù)等條件,把或、與、非關系理順;
3、進而練習整數(shù)運算、實數(shù)運算、類型轉(zhuǎn)換;
4、量程轉(zhuǎn)換、PID調(diào)節(jié)回路的建立及P、I、D參數(shù)的理解(最好是有個物理回路驗證,比如變頻器+電機+測速傳感器);
5、循環(huán)、順序、跳轉(zhuǎn)等程序控制(盡量避免跳轉(zhuǎn),非跳不可時也是跳的越近越好);
6、中斷、通訊、位置控制....

本人以ABB工業(yè)機器人配件DSQC系列和Motorola MVME系列,GE 卡件 模塊 驅(qū)動器系列為主攻。各位電工朋友可根據(jù)自己的條件選擇適合自己的PLC品牌,由于PLC的基本框架大同小異,學會一種至于其它的學習起來也就簡單了。
