程序設計
1.程序設計
根據(jù)系統(tǒng)的控制要求,采用合適的設計方法來設計PLC程序。程序要以滿足系統(tǒng)控制要求為主線,逐一編寫實現(xiàn)各控制功能或各子任務的程序,逐步完善系統(tǒng)的功能。除此之外,程序通常還應包括以下內(nèi)容:
1)初始化程序。在PLC上電后,一般都要做一些初始化的操作,為啟動作必要的準備,避免系統(tǒng)發(fā)生誤動作。初始化程序的主要內(nèi)容有:對某些數(shù)據(jù)區(qū)、計數(shù)器等進行清零,對某些數(shù)據(jù)區(qū)所需數(shù)據(jù)進行恢復,對某些繼電器進行置位或復位,對某些初始狀態(tài)進行顯示等等。
2)檢測、故障診斷和顯示等程序。這些程序相對獨立,一般在程序設計基本完成時再添加。
3)保護和連鎖程序。保護和連鎖是程序中不可缺少的部分,必須認真加以考慮。它可以避免由于非法操作而引起的控制邏輯混亂。
2.程序模擬調(diào)試
程序模擬調(diào)試的基本思想是,以方便的形式模擬產(chǎn)生現(xiàn)場實際狀態(tài),為程序的運行創(chuàng)造必要的環(huán)境條件。根據(jù)產(chǎn)生現(xiàn)場信號的方式不同,模擬調(diào)試有硬件模擬法和軟件模擬法兩種形式。
1)硬件模擬法是使用一些硬件設備(如用另一臺PLC或一些輸入器件等)模擬產(chǎn)生現(xiàn)場的信號,并將這些信號以硬接線的方式連到PLC系統(tǒng)的輸入端,其時效性較強。
2)軟件模擬法是在PLC中另外編寫一套模擬程序,模擬提供現(xiàn)場信號,其簡單易行,但時效性不易保證。模擬調(diào)試過程中,可采用分段調(diào)試的方法,并利用編程器的監(jiān)控功能。
