PLC程序設(shè)計步驟。
PLC程序設(shè)計一般分為以下幾個步驟:
1. 程序設(shè)計前的準備工作
程序設(shè)計前的準備工作就是要了解控制系統(tǒng)的全部功能、規(guī)模、控制方式、輸入/輸出信號的種類和數(shù)量、是否有特殊功能的接口、與其它設(shè)備的關(guān)系、通信的內(nèi)容與方式等,從而對整個控制系統(tǒng)建立一個整體的概念。接著進一步熟悉被控對象,可把控制對象和控制功能按照響應(yīng)要求、信號用途或控制區(qū)域分類,確定檢測設(shè)備和控制設(shè)備的物理位置,了解每一個檢測信號和控制信號的形式、功能、規(guī)模及之間的關(guān)系。
2. 設(shè)計程序框圖
根據(jù)軟件設(shè)計規(guī)格書的總體要求和控制系統(tǒng)的具體情況,確定應(yīng)用程序的基本結(jié)構(gòu)、按程序設(shè)計標準繪制出程序結(jié)構(gòu)框圖,然后再根據(jù)工藝要求,繪出各功能單元的功能流程圖。
3. 編寫程序
根據(jù)設(shè)計出的框圖逐條地編寫控制程序。編寫過程中要及時給程序加注釋。
4. 程序調(diào)試www.plcs。。cn
調(diào)試時先從各功能單元入手,設(shè)定輸入信號,觀察輸出信號的變化情況。各功能單元調(diào)試完成后,再調(diào)試全部程序,調(diào)試各部分的接口情況,直到滿意為止。程序調(diào)試可以在實驗室進行,也可以在現(xiàn)場進行。如果在現(xiàn)場進行測試,需將可編程控制器系統(tǒng)與現(xiàn)場信號隔離,可以切斷輸入/輸出模板的外部電源,以免引起機械設(shè)備動作。程序調(diào)試過程中先發(fā)現(xiàn)錯誤,后進行糾錯?;驹瓌t是“集中發(fā)現(xiàn)錯誤,集中糾正錯誤”。
5. 編寫程序說明書
在說明書中通常對程序的控制要求、程序的結(jié)構(gòu)、流程圖等給以必要的說明,并且給出程序的安裝操作使用步驟等。
