Real-Time data transfer issue, from FPGA to RT

Status: New

Hello  Everyone, 

 

I apologize if I repeat this topic, but I need help with a particular application. I have read a lot of discussions but it seems that I don't find the solution.
I have a cRIO-9068 with 5 modules of analog inputs (NI9215), and I'm using the Labview '13.
I have to read in real-time simultaneously 6 signals (3 voltages and 3 currents) and save them on the PC. The saving process works fine (I'm saving the data using TDMS functions), but I have an issue with data transfer from FPGA to RT VI. I don't know why, but no matter what I do, I don't read all the data, or I read them wrong. The FPGA reads all the 6 channels once at 50us (20kHz).
The FIFO settings are: -Requested number of elements: 1023; -Data type: FXP, Signed, 26bits/5bits.

 

I have attached both programs (FPGA and RT).

 

I will be grateful for any guidance or advice! 

I wish you the best!
Martin Adrian.
