NI DAQ collection device is always in the running state. When I start to click the Run button, vi program automatically creates a file, and data is automatically imported into this file every 10 minutes. After 1 hour, the file is automatically closed and a new file is automatically created, and the collected data is imported into the new file every 10 minutes. Until 1 hour later the new file is automatically closed again and another new file is created, and the process is repeated repeatedly. Until I stop running this program, this is the vi program I do, but I can not achieve the above mentioned things, I hope there is a big man to help me, thank you

Much easier way to do this. Use the built in logging features of DAQmx. Use your sample rate times 3600 (seconds in an hour) to tell DAQmx logging how big you want each file. Every hour from your acquisition start DAQmx will start a new file. (Test it by changing 3600 to 10, you will see a new file every 10 seconds)

LabVIEW

New files are automatically created every hour to store the data being collected by the NI cDAQ

Solved!

Thank you for your reply, I know the way to use the unique file name, but I don't know how to combine this method with the hourly data storage program to achieve the content of my reply post mcduff above

I am not clear what you want. Do you want to append data to the original files? If so, change the modifier on the Logging VI from Create or Replace, to Open or Create.
