How can i save/load digital waveform to file

[LabJoe]

Hi,

i have a digital waveform chart which acquires continuous digital data for a specific time. After that i want to save the contents of the digital waveform chart to file. The functions i found do not work with digital data.
I also want the possibility to load the saved data back to my chart.
Any ideas ?

Thanks in Advance

Try NI-HWS. It can be found on the last two driver CDs (it is part of NI-FGEN, NI-SCOPE, NI-HSDIO, and both the analog and digital waveform editors).

For saving digital waveform data unfortunately there is no wavaform VI available. But you can use the normal "Write File" and "Read File" VI´s from the File I/O palette. this VI´s are able to save Clusters to binary files. For the Read Function do you need the datatype information wired to the VI Input.
hope that helps.

I beg to differ. As I mentioned before, check out NI-HWS. The VIs take digital, as well as analog, waveforms. NI-HWS has several other advantages as well. It is binary, so it is fast. It has optional compression. It does not have a 2GByte file size limit. You can store multiple waveforms of multiple types in the same file and retrieve them by name. Go for it. It is on any driver CD dated May 2004 or later.

I've designed code to do the same today.  Using LabVIEW 8.5 the TDMS VIs can be used to save and load digital waveform data.
