Hey guys,
I'm really at wit's end with this problem
Background Info:
I am trying to read data from 5 thermocouples (5 channels)
What I need is collect and record continuous data (possibly for a long period of time) at 1kHz and maybe have it buffer every one second?
(If I have a 1 second buffer than I basically am seeing real time data in my graphs which is what I want)
I also need to a real time temperature vs. time graph
And a dT/dt vs. -1000/T graph
I have this all coded up, but I am continually running into the same problem
when I am recording my data, (say at 1kHz and recording 1000 samples per second (buffer time is then 1s)) I'm using several write to measurement files to record my T vs. t data, my dT/dt vs. -1000/T data and then I am taking every fifth element of each of those and writing it to another measurement file
***Here is the big problem***
The VI records samples at time 0.000-1.000 and then starts recording again at 0.000-1.000 everytime it buffers. I really need this to continue counting up and not reset every time it buffers
I am uploading My VIs and sub VIs
Be warned that it is messy, I’m new to this and I just want to get the code working before I worry about cleaning it up
I have looked at all the daqmx examples but I cannot get any of them to do what I want
Any help would be much appreciated
Thank You,

nevermind I figured it out. I got rid of the constants controlling my for loops
