SOLVED: CC-Link Data Link Error, All stations drop

[WattUp 34]

We have a new machine that we are trying to get setup.  We are having a strange symptom that we have never seen.

 

Every 8-10minutes the Entire CC link network will drop off shutting everything down. At first we thought it was the 24v dropping, but have eliminated that now with our meter.  I ran a CC-Link log and it does show every single station come up in an ‘Data Link error’.
