Streaming Individual Channels to File

[Parallax]

Hello,

     Im new to labveiw and if there is a better way to do what im proposing im all ears. Basicaly I am going to be collecting 12+hours of data at 51200Hz on 128 Channels, 32 channels per cDAQ Chassis. Lets start with a simple case of 1 cDAQ chassis and 32 channels at 51200Hz. By my calculations this could be a 300+GB file if i were to write it as one array, as i am now. It would be ideal if i could write each channel to its own binary file, is there a good way to do that? Any help is very much appriciated.

Good Afternoon,

I believe that you would have to create a separate DAQmx task per channel to do this.  However, belopw is a KnowledgeBase article detailing how to write to a binary file.  Hope this helps!
