IO Limit

Hi All

I am planing to do a test bench with 3 x NI9178 racks controlled by one PC.

I am using the NI-DAQmx API (nidaqmx.lib) and have created a C++ wrapper class to control the IO's.

I have approximately 300 IO's. The signals are primary DI and DO (NI9425, NI9476).

My question: Is there a limit to how many IO's or racks that can be controlled with the NI-DAQmx?

Best Regards
