Number of CAN HS cards supported in a CompacDAQ

[telloagm]

Hi everyone, 

could somebody tell me , how many CAN HS cards a COmpacDAQ supports?  I would like to have three independen CAN HS channels running in parallel.

Kind Regards,

I don't believe there is a limit to the number of channels of HS CAN cDAQ supports. Are you running into any trouble running three channels in parallel?

Hi, 

here you can find How Many Different Tasks Can Concurrently Run on a CompactDAQ Chassis https://www.ni.com/en/support/documentation/supplemental/18/number-of-concurrent-tasks-on-a-compactd...

There is no hard limit to the number of CAN HS modules from the software or hardware. But depending on your baud rate + number of channels + which CompactDAQ chassis you are using + how the application is written, the physical data transfer bus might not be able to keep up due to performance limitations.
