描述

1769-L30ER

同一個繼電器線圈在同一個程序中使用兩次稱為雙線圈輸出,雙線圈輸出容易引起誤動作,在程序中盡量要避免線圈重復使用。如果必須是雙線圈輸出,可以采用置位和復位操作(以S7-300為例如SQ4.0或者RQ4.0)。
? ? 如果要使PLC多個輸出為固定值1(常閉),可以采用字傳送指令完成,例如Q2.0、Q2.3、Q2.5、Q2.7同時都為1,可以使用一條指令將十六進制的數(shù)據(jù)0A9H直接傳送QW2即可。
? ? 對于非重要設備,可以通過硬件上多個觸點串聯(lián)后再接入PLC輸入端,或者通過PLC編程來減少I/O點數(shù),節(jié)約資源。例如:我們使用一個按鈕來控制設備的啟動/停止,就可以采用二分頻來實現(xiàn)。
? ? 模塊化編程思想的應用:我們可以把正反自鎖互鎖轉(zhuǎn)程序封裝成為一個模塊,正反轉(zhuǎn)點動封裝成為一個模塊,在PLC程序中我們可以重復調(diào)用該模塊,不但減少編程量,而且減少內(nèi)存占用量,有利于大型PLC程序的編制。
? ? 4PLC控制系統(tǒng)程序的調(diào)試
? ? PLC控制系統(tǒng)程序的調(diào)試一般包括I/O端子測試和系統(tǒng)調(diào)試兩部分內(nèi)容,良好的調(diào)試步驟有利于加速總裝調(diào)試的過程。
? ? 4.1I/O端子測試
? ? 用手動開關暫時代替現(xiàn)場輸入信號,以手動方式逐一對PLC輸入端子進行檢查、驗證,PLC輸入端子的指示燈點亮,表示正常;反之,應檢查接線或者是I/O點壞。
? ? 我們可以編寫一個小程序,在輸出電源良好的情況下,檢查所有PLC輸出端子指示燈是否全亮。PLC輸入端子的指示燈點亮,表示正常。反之,應檢查接線或者是I/O點壞。
? ? 4.2系統(tǒng)調(diào)試
? ? 系統(tǒng)調(diào)試應首先按控制要求將電源、外部電路與輸入輸出端子連接好,然后裝載程序于PLC中,運行PLC進行調(diào)試。將PLC與現(xiàn)場設備連接。在正式調(diào)試前全面檢查整個PLC控制系統(tǒng),包括電源、接地線、設備連接線、I/O連線等。在保證整個硬件連接正確無誤的情況下即可送電。
? ? 把PLC控制單元的工作方式設置為“RUN”開始運行。反復調(diào)試消除可能出現(xiàn)的各種問題。在調(diào)試過程中也可以根據(jù)實際需求對硬件作適當修改以配合軟件的調(diào)試。應保持足夠長的運行時間使問題充分暴露并加以糾正。調(diào)試中多數(shù)是控制程序問題。一般分以下幾步進行:
? ? (1)對每一個現(xiàn)場信號和控制量做單獨測試;
? ? (2)檢查硬件/修改程序;
? ? (3)對現(xiàn)場信號和控制量做綜合測試;
? ? (4)帶設備調(diào)試;
? ? (5)調(diào)試結(jié)束。
? ? 5結(jié)束語
? ? PLC控制系統(tǒng)的設計是一個步驟有序的系統(tǒng)工程,要想做到熟練自如,需要反復設計和實踐。本文是PLC控制系統(tǒng)的設計和實踐經(jīng)驗的總結(jié),在實際應用中具有良好的效果。

15天包退換 一年質(zhì)保 大量現(xiàn)貨? 國內(nèi)實力庫存商家


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,??怂共_、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。
