Comparison between DAQmx driver performance and SWITCH driver performance?

[wakas]

Hello all!

So I discovered that some particular devices, e.g. PXI-2529 matrix switch module, are supported by both DAQmx and SWITCH drivers.

I wanted to ask whether someone has experimented with both and can list some pros and cons of either approach?

1. Is SWITCH driver more suitable for PXI-2529 compared to DAQmx? (provides more function calls?)

2. Is there execution time or error handling difference between the two? 

3. What is the point of having two compatible drivers to one HW device? (there must be something I'm failing to understand)

Background here is that I've started experimenting with the python libraries for NI Hardware (https://nimi-python.readthedocs.io/en/master/) 

And I would like to decide whether to continue with DAQmx for our relay, mux, matrix HW devices or go down the NI-SWITCH driver route. 

Thanks for your help!

BR,

NI Switch driver is recommended for all relay/switch cards. I believe initially, it started with DAQmx and separated the functionality into NI-Switch drivers. There could have been a grey area during the transition period.
