VisualStudio2010-C#跟西门子1200(Sharp7)-简单上位机界面⑨-IO
上期回顾（上期主要是对PLC的输出监控代码进行了编写，让其在定时器响应程序中，不断实时读取PLC，到这里IO监控的输入输出读取都已经实现了）
本期将调试下，看是不是能实时读取到PLC输入输出的状态
1.0 先看下我们前面制作的界面，大体上是这样的
2.0 然后我们的代码应该是这样的

3.0 PLC这边要做个手动置位输出点的编辑，如下图，当变量"MUN".Static_1等于1时，Q0.0导通，这样类似的做几个，等会调试用
4.0 保存，按F5调试
5.0 PLC按监控，然后修改变量"MUN".Static_1修改操作数为1，这时候就强制导通了Q0.0
6.0 这时候回到看下C#界面，代表Q0.0的点亮了，
7.0 如果外部强制给一个输入给PLC，你就会发现对应的输入点，其他应该也是OK的
