描述

1FK7042-5AK71-1GB3

?PLC編程語言的形式
? ? 本教材采用最常用的兩種編程語言，一是梯形圖，二是助記符語言表。采用梯形圖編程，因為它直觀易懂，但需要一臺個人計算機及相應的編程軟件；采用助記符形式便于實驗，因為它只需要一臺簡易編程器，而不必用昂貴的圖形編程器或計算機來編程。
? ? 雖然一些高檔的PLC還具有與計算機兼容的C語言、BASIC語言、專用的高級語言（如西門子公司的GRAPH5、三菱公司的MELSAP），還有用布爾邏輯語言、通用計算機兼容的匯編語言等。不管怎么樣，各廠家的編程語言都只能適用于本廠的產(chǎn)品。
? ? 編程指令：指令是PLC被告知要做什么，以及怎樣去做的代碼或符號。從本質上講，指令只是一些二進制代碼，這點PLC與普通的計算機是完全相同的。同時PLC也有編譯系統(tǒng)，它可以把一些文字符號或圖形符號編譯成機器碼，所以用戶看到的PLC指令一般不是機器碼而是文字代碼，或圖形符號。常用的助記符語句用英文文字（可用多國文字）的縮寫及數(shù)字代表各相應指令。常用的圖形符號即梯形圖，它類似于電氣原理圖是符號，易為電氣工作人員所接受。
? ? 指令系統(tǒng)：一個PLC所具有的指令的全體稱為該PLC的指令系統(tǒng)。它包含著指令的多少，各指令都能干什么事，代表著PLC的功能和性能。一般講，功能強、性能好的PLC，其指令系統(tǒng)必然豐富，所能干的事也就多。我們在編程之前必須弄清PLC的指令系統(tǒng)
? ? 程序：PLC指令的有序集合，PLC運行它，可進行相應的工作，當然，這里的程序是指PLC的用戶程序。用戶程序一般由用戶設計，PLC的廠家或代銷商不提供。用語句表達的程序不大直觀，可讀性差，特別是較復雜的程序，更難讀，所以多數(shù)程序用梯形圖表達。
? ? 梯形圖：梯形圖是通過聯(lián)機把PLC指令的梯形圖符號連接在一起的連通圖，用以表達所使用的PLC指令及其前后順序，它與電氣原理圖很相似。它的聯(lián)機有兩種：一為母線，另一為內部橫豎線。內部橫豎線把一個個梯形圖符號指令連成一個指令組，這個指令組一般總是從裝載（LD）指令開始，必要時再繼以若干個輸入指令（含LD指令），以建立邏輯條件。最后為輸出類指令，實現(xiàn)輸出控制，或為數(shù)據(jù)控制、流程控制、通訊處理、監(jiān)控工作等指令，以進行相應的工作。母線是用來連接指令組的。

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、類型轉換；
4、量程轉換、PID調節(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、跳轉等程序控制（盡量避免跳轉，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。
