Hi there,
What an interesting case we got here! 🙂
First, let's reset the NI MAX configuration:
- Disconnect the cRIO from the network (or USB)
- Go to NI MAX > Tools (in taskbar on top) > Reset Configuration Data (this will restart thePC)
- Try the procedure again of creating a project
Second, let's make sure that all the NI-9476 are working well:
- Remove all the modules from the cRIO
- Add only one NI-9476 and create a new project and let LabVIEW detect modules
- If the single module is detected, meaning that it does not have a problem
- Repeat the procedure for the 2 other NI-9476 modules
Third, if you have not seen it yet, check the following article: Adding a New C Series Module to a cRIO Project in LabVIEW
Forth, if all the steps were not effective, please share some screenshots of your project so I can look into it deeper.
Cheers,
