Issue Details

I have a system using EtherCAT. This could be on a cRIO, PXI or other system using EtherCAT.
I updated or changed my operating system and now my communications don't work. How do I fix this?


When you update or change Operating Systems, some protocols or addresses may change.
Manually add the systems to a blank LabVIEW project and check the addresses used in this project.
After confirming basic communication, update the relevant code to the new addresses.

If the problem persists, contact NI Technical Support.
