CRIO's acquisition capacity

[k.nadia]

Hi,

I'm using CRIO to acquire digital inputs, and each one requires a frequency of 1kHz, in this case I'm Afraid to exceed CRIO's acquisition Capacity knowing that CRIO requires a frequency less than 500Hz

In your Opinions, It is dangerous what I'm trying to do ?

Thank you in advance for your advices

My Kind  regards

What digital module are you using?  Are you using the FPGA?  What cRIO are you using?

I'm using module NI 9403 (Scan Interface)

Yeah, the scan interface can't go that fast.  But that module will work at up to 140kHz.  You will want to change to the FPGA interface in order to do this properly.
