Hi all, I read in input voltage data using PCI 6143 throught finite sampling. This VI is supposed to, for example, after acquiring 240 samples, I write all collected voltages to an excel file. Before I write the data into excel, I need to re-arrange the data array. This re-arranging task takes up quite a significant amount of time (about ~30ms). Hence, the 2nd batch of 240 samples collected is only done after arranging data and writing to file. Hence the process will be like, 0.9milli sec of data, wait 30milli sec, 0.9milli sec of data, wait 30milli sec and so on. So is it possible to pass this huge chunk of data to another VI, specifically doing the data manipulation and writing to file while the main VI continue collecting the voltage data without data losses? Does anyone have any suggestion by which mean am I able to do this? I saw a nice example in LV 7.1 example finder-> optimizing applications synchronizing tasks->Pass Data with Notifiers.vi Is this notifier method the solution to my problem or is there some other means to achieve the results? Thanks everybody! Best regards, Dick

Hi Kalyan,

Hope you had a nice weekend. Thanks for your reply.

I couldn't open your example cos it's version 8.0. My labview is version 7.1.

Can you re-save it as 7.1 please? Thanks again.

Regards,

Dick

Hi Dick,

Sorry about that. I am attaching the code in LV 7.1.

Thanks,
