Hi KC089,
I've taken a look into what could be causing this issue. From what I can tell, this is similar to the issue discussed in our article Modules in Ethernet cDAQ Chassis Are Not Recognized in MAX.
As the article mentions, this behavior is caused by the Ethernet cDAQ chassis not being automatically reserved by the computer. This is a protective measure in case the chassis is in use with another computer.
The article suggests using the Self-Test function to reserve the chassis after rebooting. If you Self-Test the chassis, does the module appear correctly in the chassis?
Kind regards,
