As a RT system, you can not read the module on the cRIO system.
But you can create the "terminal and device..." in project manager in LabVIEW, and if you can call the related interface, you have linked the device correctly.
By the way,you have said "As a RT system, you can not read the module on the cRIO system." Does this means that i couldn't find the usb raw device in MAX on my computer either?
