EB401-10

PLC程序設(shè)計(jì)步驟。
PLC程序設(shè)計(jì)一般分為以下幾個(gè)步驟：
1. 程序設(shè)計(jì)前的準(zhǔn)備工作
程序設(shè)計(jì)前的準(zhǔn)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(hào)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(duì)整個(gè)控制系統(tǒng)建立一個(gè)整體的概念。接著進(jìn)一步熟悉被控對(duì)象，可把控制對(duì)象和控制功能按照響應(yīng)要求、信號(hào)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(gè)檢測信號(hào)和控制信號(hào)的形式、功能、規(guī)模及之間的關(guān)系。
2. 設(shè)計(jì)程序框圖
根據(jù)軟件設(shè)計(jì)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(jì)標(biāo)準(zhǔn)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(jì)出的框圖逐條地編寫控制程序。編寫過程中要及時(shí)給程序加注釋。
4. 程序調(diào)試www.plcs。。ｃｎ
調(diào)試時(shí)先從各功能單元入手，設(shè)定輸入信號(hào)，觀察輸出信號(hào)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(shí)驗(yàn)室進(jìn)行，也可以在現(xiàn)場進(jìn)行。如果在現(xiàn)場進(jìn)行測試，需將可編程控制器系統(tǒng)與現(xiàn)場信號(hào)隔離，可以切斷輸入/輸出模板的外部電源，以免引起機(jī)械設(shè)備動(dòng)作。程序調(diào)試過程中先發(fā)現(xiàn)錯(cuò)誤，后進(jìn)行糾錯(cuò)?；驹瓌t是“集中發(fā)現(xiàn)錯(cuò)誤，集中糾正錯(cuò)誤”。
5. 編寫程序說明書
在說明書中通常對(duì)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。
