Hello all,
I am using cRIO-9025 and LABVIEW to develop a data aquisition system and met a problem. I am trying to use NI 9023 to sample from several current channels in scan mode. At the same time, I also need to use NI 9871 to read from serial devices in FPGA mode. Hence I need to use both of the two modes in the same project. I have already created a project containing the two modes following the link below:

Since I need to sample current and read from serial devices simultaneously, I add the code in scan mode for current sampling to the host vi of FPGA mode for NI 9871. What I did was just past the scan mode code under the original code in the host vi. However, when I run the vi, the code in scan mode can not sample at the expected rate. I set the timed loop to sample at 100 Hz, but it turns out that it only sample current 3 or 4 times a second. It seems that scan mode can not work as expected when put with FPGA in same host vi.
May I ask is there any method for me to solve this problem? How can I achieve to run both scan mode code and FPGA code at the same time?
Thank you very much for your help.
