描述
在PLC的編程方法中,經(jīng)驗法一直受到許多從業(yè)者的青睞,并且在經(jīng)驗設(shè)計法中資料收集顯得尤為重要。首先收集典型程序樣例,程序最好有較完整的組成部分:控制任務(wù)、I/O分配、硬件接線圖、完整的程序及注釋。其次要讀懂程序,從而分解出程序中用于完成不同任務(wù)的組成部分,對于各組成部分中獨立完成某一特定功能的子程序或者中斷程序應(yīng)及時收藏到程序庫。以便在以后的編程過程中碰到實現(xiàn)類似控制任務(wù)時,節(jié)約程序設(shè)計時間、提高程序調(diào)試成功率。再次還需要記錄程序閃光點,諸如編程者巧妙的思路、程序結(jié)構(gòu)、應(yīng)用指令的使用。尤其是應(yīng)用指令的使用,能夠大大的縮短程序長度,減少內(nèi)存容量,降低系統(tǒng)成本。最后對程序做功能擴(kuò)展性的設(shè)計、調(diào)試,并對全過程加以詳細(xì)記錄、再加以總結(jié)。通過以上過程就能夠有效消化這些程序范例,使其融入到自己以后的編程過程中。經(jīng)過一段時間的資料收集、理解、消化后,逐步確立適合自己的編程方法。
