各位前輩好,小弟現在在使用cRIO-9063,擴充卡為9225和9247,我想個別用兩個擴充卡抓取電流和電壓,程式方面我是由NI的範例來更改,但執行後只有一個通道能抓取到值,另一個則會顯示錯誤( Error -61202 :LabVIEW could not perform the operation because an FPGA VI reference to another VI is currently open. You must close the currently open FPGA VI reference before attempting to perform this operation.),以下是我的程式,請問有什麼方法能改善這個問題 感謝
