I am using a PXIe-2727 and PXI-2520 in my system. The controller (PXIe-8880) came with Windows 10 installed. I did my initial testing/checkout with Windows because of the nice GUIs. I have since provisioned the controller to run NI Linux RT and when installing software noticed that NI SWITCH driver does not exist for Linux. I have installed NI Serial (for serial modules) and NI DAQmx (for analog and digital IO modules) and the associated modules appear in MAX as expected, but the 2 relay modules mentioned above are missing. Is there an equivalent to NI SWITCH in Linux RT? I am programming in C and will be using DAQmx to control these relay modules however I won't be able to do that if the system doesn't recognize them in the first place. Any ideas?
