How to store a DAQmx task properties efficiently ?

[mseb]

Hello all and Happy new year !

I'd like to be able to keep track of all the parameters of a DAQmx task (and its channels) in a file, whatever the content of the DAQmx Task / Channel is. Up to now the only way I've found is to use a DAQmx Task / Channel property nodes and deal with every possible property. However, since they are so many properties, each one not being valid for any hardware or Task / Channel type, it's a really huge work and I'm rather lazy  😉

So I'm asking here if anybody has already dealt with this or has an idea ?

Hi Mseb,

Thanks for the post and I hope your well.

I have not seen or heard of a better method then it appears your talking about. 

In this dev zone article,

Capturing NI-DAQmx Configuration into TDM Files

Contents 2.DAQmx Information - Channel and Task Properties

http://zone.ni.com/devzone/cda/tut/p/id/3079#toc1

shows an example vi  - this could help?

Would it be possible to post some example code to get more details on how your currently generating this data?

Hope this helps,

Hi Hillman,

Thank you very much for the link. Silly me had overlooked tdm related documents... Your link is indeed very relevant, since I'm doing it right now exactly the same way as it's done in the :

• DAQmxTaskInfoQuery.vi
• General DAQmx TEDS Info.vi

Which are part of the download indicated in the link you gave.

Exepted that this code is much more readable than mine, thus I guess I don't need to post my incomplete ugly code. Many interresting things there, thank you very much. I'll be back if I have anything better to give as reference.
