Kontinuierliche Datenerfassung, Continuous data collection

[Dennis_Knutson]

The waveform data type has the t0 and dt. That is all that you need. Use the function on the waveform palette if you think you need a timestamp array.

[Christoph8446]

No I mean the exact point of time when the value is measured by the sensor and recognized by the NI 9208 card (rack buffer)!

I have no RT-system and I use the buffer on the rack!

[Dennis_Knutson]

You keep repeating the question after getting the answer. Are you even a little bit acquainted with LabVIEW and the waveform data type?

Buffer on the rack is meaningless to me.

[Christoph8446]

The hardware card NI 9208 reads the sensor value and the value is stored in the buffer of the rack(chassis) the DQmax driver streams the data fom the buffer to the PC (buffer because of no RT-system)! The time which you suggest me is not useful for me because there is a discrepance to the real time value!

[Dennis_Knutson]

What is this real time value you are talking about? How are you reading it? What is the discrepancy? What is the chassis?

[Phox3]

If you use an external start trigger for your task, this should give you the exact time that data collection is started (t0 as mentioned previously). You can use the PFI lines on your chassis as the start trigger source.
