Hi Stefanb1
Usually, if a RIO device such as a compactRIO or sbRIO isn't appearing in MAX, there may be a few different reasons. Firstly, have you installed the NI-RIO drivers on to your PC? It's important that you've installed your software in the correct order, with the development suite first, then the extra modules and toolkits (such as the robotics toolkit) and finally, drivers (NI-RIO).
If you have installed your software in the correct order, please ensure the quality of your ethernet cable and connection.
