夏普空調TIMER亮黃燈怎么回事(夏普空調亮黃燈怎么回事)

前沿拓展：

VisualStudio2010C跟西門子1200(Sharp7)簡單上位機界面⑨IO

上期回顧（上期主要是對PLC的輸出監控代碼進行了編寫，讓其在定時器響應程序中，不斷實時讀取PLC，到這里IO監控的輸入輸出讀取都已經實現了）

本期將調試下，看是不是能實時讀取到PLC輸入輸出的狀態

1.0 先看下我們前面制作的界面，大體上是這樣的

2.0 然后我們的代碼應該是這樣的

3.0 PLC這邊要做個手動置位輸出點的編輯，如下圖，當變量&34;MUN&34;.Static_1等于1時，Q0.0導通，這樣類似的做幾個，等會調試用

4.0 保存，按F5調試

5.0 PLC按監控，然后修改變量&34;MUN&34;.Static_1修改操作數為1，這時候就強制導通了Q0.0

6.0 這時候回到看下C界面，代表Q0.0的點亮了，

7.0 如果外部強制給一個輸入給PLC，你就會發現對應的輸入點，其他應該也是OK的
