Have you tried to re-format it, perhaps using a USB drive? Here is a link with the steps to try:
Now, I can see the system in MAX software (under Remote Systems) and I have installed LabVIEW Real-Time 18.0 to the controller.
However, it is still empty under MAX>Remote Systems>Devices and Interface. I can not see my controller and chassis.
How can I find my device please?
problem solved. I installed NI-VISA Server 17.5 to the controller, and now both chassis and controller can be found under Devices and Interfaces branch.
