夏普空調(diào)TIMER亮黃燈怎么回事(夏普空調(diào)亮黃燈怎么回事)
前沿拓展：
VisualStudio2010-C#跟西門子1200(Sharp7)-簡(jiǎn)單上位機(jī)界面⑨-IO
上期回顧（上期主要是對(duì)PLC的輸出監(jiān)控代碼進(jìn)行了編寫(xiě)，讓其在定時(shí)器響應(yīng)程序中，不斷實(shí)時(shí)讀取PLC，到這里IO監(jiān)控的輸入輸出讀取都已經(jīng)實(shí)現(xiàn)了）
本期將調(diào)試下，看是不是能實(shí)時(shí)讀取到PLC輸入輸出的狀態(tài)
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(yīng)該是這樣的

3.0 PLC這邊要做個(gè)手動(dòng)置位輸出點(diǎn)的編輯，如下圖，當(dāng)變量"MUN".Static_1等于1時(shí)，Q0.0導(dǎo)通，這樣類似的做幾個(gè)，等會(huì)調(diào)試用
4.0 保存，按F5調(diào)試
5.0 PLC按監(jiān)控，然后修改變量"MUN".Static_1修改操作數(shù)為1，這時(shí)候就強(qiáng)制導(dǎo)通了Q0.0
6.0 這時(shí)候回到看下C#界面，代表Q0.0的點(diǎn)亮了，
7.0 如果外部強(qiáng)制給一個(gè)輸入給PLC，你就會(huì)發(fā)現(xiàn)對(duì)應(yīng)的輸入點(diǎn)，其他應(yīng)該也是OK的
