OK,

i'll try that and let you know the results..

Thank you

Hi,

I am having a problem with data transfer on RT target using global or local variable.

My system configuration is:

128 AI channels (4 CRIO 9205) with 2000 Hz sampling rate.(I am using 3M FPGA and 9014 RT controller)

I am using DMA FIFO for data transfer from target to host (2 DMA FIFOS) and read 100 ms or 200 samples on RT host.

I need to transfer data to HOST PC for analysis.

I set up a TCP/IP connection between RT and PC. All works fine when I send data that I read from DMA FIFO in the same loop .

What I want is to have a communication loop that runs in parallel with main loop and sends data to the PC.

I tried to transfer data using global or local variables but I have encountered a problem of data loss somewhere in that process.

My data loss is always on 200 -th, 400 -th etc.. point (I belive that it has to do with reading blocks from FIFO??).

What can be the problem.

Thank you in advance!
