紧急系统要求即时的响应。中断编程技术可使某事件在一个程序扫描期间内立即被激活,与它实际在程序中的位置无关。
给出的这个非常简单的紧急系统说明:在任何时刻,如果安全门被打开,一个专用的中断输入(X001)触发中断程序I101l。当输入X001从OFF变为ON时,指针I101同时作为程序标记和所使用的中断的标记。当中断处理完,程序控制返回到“紧急情况”前执行的最后一步。这样处理是很有用的,它帮助编程者保持程序的编程顺序。主要的问题是某个特殊功能被激活或者一个子程序运行,
并且当控制返回主程序时,操作顺序与机器操作不协调。使用任何形式的“程序中断”时都应小心。
中断运行完毕,输出Y005设置为ON。本例中,铃声响起,由此作为声音警报。本程序中通过激活输入X004使警报复位。
