1769L18ERM是campatlogix中新推出的一款處理器,用慣了老系列的,發(fā)現(xiàn)這種新推出的處理器還是有些特殊的地方。這不,下載程序的時候就出了個The controller acknowledged the request for a transition to Remote Program mode, but it has not completed the transition. You can't download until the transition completes. Error 747-0 不要以為是編程軟件的問題。把運行編程的撥碼撥到PRO后,處理器的RUN燈還亮著,呵呵,也不是處理器的撥碼開關壞了。那到底是什么問題呢?請看這段說明: Cause The controller has to wait until all pending messages (including block transfers) and motions have completed before completing the mode change. When the ControlLogix (CL) processor receives a command from the key switch or software to transition to program mode, it has to shut down all connections and motions. All MSG instructions (both messaging and block transfers) must complete or timeout, and all I/O connections must close or timeout before the Run light turns off. Also, motion instructions that are in progress have to reach safe-stopping points before they can stop. Other outside communications, such as HMI or spreadsheet data requests via DDE, can cause slow transitions, too. 簡單的說就是:這個處理器是支持伺服的,那么處理器認為會有某些軸還沒有被安全的停止,或者處理器還在和外部設備通信。處理器會等待這些都完成后,它才會切換模式。因此在這個時候你要下載程序就會出現(xiàn)上面的那個提示。 解決的辦法是什么? 就是你把處理器撥到PRO狀態(tài),等待幾分鐘后,待RUN等熄滅后,其他操作就都正常了,你去下載程序什么的就沒問題了。
