Issue Details

I'm trying to store the data that I acquire on my cRIO on a TDMS file. I have written an application that runs on the cRIO that writes to a TDMS file. I have specified the file path in TDMS Open as a location on my computer. When I run the code I get error 7.


In order to store data acquired with the cRIO on the computer (host) the data must first be transferred. Continuous data transfer between a RT target and the host can be achieved using:
  • Network Published Shared variables with RT FIFO enabled
  • Network Streams
