Hi, I am working with cRio 9074 and ni 9234 module, In the VI works, but the adquisition data is so slow (one data per second) because I couldn't sincronize the pc with the scan engine...How would achieve the comunication both the chasis and the pc?
Solved! Go to Solution.

I'm working with LabView 2010 and followed the scan mode example on the NI website, but still cant get the data, my question is about the communication between the scan engine and the PC, what do I need to make it work, the example uses a variable data buffer and I don't fully understand how it works, this might be the source of my confusion, also which VI goes in the PC section and which one goes in the chassis section.

Hi Sissi,
you should create a new project using the "Newā¦" menu entry. Then select a project which already has basic VIs included to
- use the ScanEngine in the cRIO RT target
- use SharedVariables to transfer data from RT target to host PC.
I know that LabVIEW comes with such projects, all you have to do is loading them and study their block diagramm comments.
which VI goes in the PC section and which one goes in the chassis section.
Once you load the project you see which VI is used in which target! Each target has it's own branch in the project treeā¦
