How can I intercept the data for 5 seconds before the errormessage?

[xyfee]

I need a function:

 When prgramm find an error, preserve the data  that are former and after 5 seconds from the error. Need not to preserve if no error. How can I intercept the data for  5 seconds before the errormessage?  

Thanks

Use a cyclic buffer that can hold up to 5 seconds of data.

While loop, shift register, array, LV2GBL, action machine

If you are using LabVIEW 8.6, you might consider using the new Lossy Enqueue function. You would need to specify the size of your queue in advance, based on your data collection rate.
