Hello Jetsoftdev,
Thank you for contacting National Instruments.
I have looked into your issue and unfortunately you cannot install VxWorks on a PXI controller. This is because the hardware requirements prevent the installation.
Also, I cannot say how difficult it is to create a VISA driver. It depends on the number and variety of commands you require of the Profinet card. I recommend that you review the Application Notes in the Hardware Connectivity Section of the
RT Third-Party Compatibility page.
Other users who may have implemented a solution along these lines may have more information on this issue. I hope this helps!
Thanks!
