Unable to Control an cRIO real Time Analog out in 1kHz

[NiklasS]

Hi, I'm wondering why I can not control an AO faster than 100Hz in cRIO Real time?
Hardware: cRIO-9067, Module NI9263 (100 kS / s / ch)
See pictures.
I would need to be able to control AO at 1kHz without the FPGA.
Does anyone have an idea.
Thanks

10ms

Because you are using the ScanEngine - with all its limitations!

Use the FPGA to get precise timings, especially at 1kHz and higher…

Thanks for your reply.
I suspected that.

The problem is that it is sporadic when we need to change the AO value. This information comes via CAN module.
Will we need to implement everything in the FPGA for this, including CAN?

I would prefer to implement it directly in the FPGA…
