同樣,如果只給I0.2置1,那么也只有Q0.1會亮,不會再影響Q0.0。
了解了IN_OUT類型變量的特點,就不難分析以上的結果。因為每次調(diào)用子程序時,局部變量#CC都會先去讀取輸入?yún)?shù)Q0.0或Q0.1的狀態(tài),所以即使兩次調(diào)用子程序時,#CC變量使用的同一區(qū)域,該區(qū)域的值也會在開始被Q點的狀態(tài)所修改,就不存在兩次調(diào)用相互影響的情況了。
另外,如果在子程序一開始就添加一條指令,對局部變量#CC進行賦初值(如圖.08),也可以避免臨時變量區(qū)數(shù)值不定的問題,您可以嘗試測試下。 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~
