DAQmx Logging New Features - Split files

[Yogesh_Redemptor]

Hi All,

With respect to this link - http://forums.ni.com/t5/Multifunction-DAQ/DAQmx-Logging-New-Features-Split-files-non-buffered-loggin... 

My requirement is - Log each one minute data in single TDMS file (irrespect of the sampling rate).

For this,

I do want to understand the "Logging - Samples per File" property node value.

The value which I am passing, needs to aligned to some "X" number.

For Example,

I am requesting "120000000 Samples per File"

But the corrected value is "120171520 Samples per File"

What is the relation between both the numbers? or How I can achieve this number pragmatically?

Can you please help me on this?

Thank you,

Yogesh Redemptor

Hello Mr.Yogesh!

This error can be resolved be wiring the Logging.FileWriteSize input of the DAQmx Read property node to the required number of samples (120,000,000) .

The corrected number in this case (120171520) is related to the size of the volume sector in bytes.
