Storing continuous stream of data

Hello,

I am currently working on writing a vi that will take 200 hz of data from multiple sensor channels and store the data points

 

Heres what i have so far. i am using a mqtt server to pull the data from

 

The "rx value' and 'rx message' are what i need to take and ideally build into a continuously updating array

right now, the data updates as a single string but does not store

That is a picture of such a time piece of your VI.  It doesn't even show anything related to storing data.

 

How do you expect us to help you with such little information?

The other information is necessary as what you've shown does not show any attempt to implement what you want.

 

Shift register,  Build Array are what you need and you learn about them in the LabVIEW tutorials:

I agree that your question is way too vague to offer help.

Your picture only shows "messageID", "RX value", and "RX topic". "rx message" is nowhere to be seen.

Define "store". Accumulate in memory (and display front panel indicator) until you run out of memory, crashing the computer? Stream to disk?

 

We cannot help unless you provide significantly more information.
