Hi, I am working on a labview project. I have a continuous input data which is updated every 100ms. I need to calculate the 15 minutes average value, one hour average value of this input data and save this average values into excel file continuously. I have problem about how to calculate the 15 minutes average input data value. I have look through some example for parallel while loop, but my main problem is how to calculate the 15 minutes average values periodically and save it to the file. Thanks for your help. Fred
