感觉都已经说清楚了，怎么找不着呢？

既然是由这些DB块对应的位“报警还是输出”，那么使用语句表就会对其访问。

是不是有些功能或功能块加密了，所以不能直接查看具体是如何实现的。

把程序传上来，没程序怎么帮你看啊

语句表很简单的，只是接触的少的话看起来会很吃力。

我把程序上传上去了，还希望各位高手指点一下，谢了！

简单看了下程序，这个是老外习惯的程序写法（应该是软件导出来的程序），这个和我们公司是一样的（西门子程序也是用软件导出自动生成的，然后再修改部分），你所要做的就是弄清楚I/O点的定义，出了问题确定I\O点是否正常就可以了，因为程序是循环嵌套的，都是指针和变量，基本上找不到具体的某一个赋值条件的。

另外头疼的是注解是德文的好像，看的我头都大了。。。

GOOD LUCK
