Issue Details

I am running a program using an ethernet cDAQ and after a day, I get the error below and I do not know why.

Solution

This error presents when the ethernet connection is lost between the computer and the cDAQ chassis. There are different ways to avoid the error:
  • Set your PC ethernet power settings to be always on.
  • Ensure you ethernet connection is not being affected by a router or switch limiting data transfer.
  • Change cables.
If all of this fails to fix the problem, it is always recommended - even if it works - to setup appropriate error handling in order to recover once the connection is restored. You will need to stop and restart the task. Refer to the related links for an example.
