我下載S7-300程序選擇“可訪(fǎng)問(wèn)節點(diǎn)”時(shí)老出已下的提示，編程適配器上的MPI，USB和電源燈常亮，偶爾幾次點(diǎn)擊連接時(shí)MPI燈在閃爍，我用的是原裝西門(mén)子6ES7  972-OCB20-OXAO編程電纜，花了4000元買(mǎi)的，搞了好長(cháng)時(shí)間了也沒(méi)好，問(wèn)題出在哪兒還望高手們指點(diǎn)，先謝謝了。

你是第一次和PLC通訊吧，看見(jiàn)你抓圖了，認為你的操作方法有問(wèn)題，不管你是上載還是下載，首先建立一個(gè)空項目，然后在設置PG/PC,然后看能否找到PLC的CPU,你看看手冊會(huì )很詳細。
