Fanuc R-30iB 120iC with Ethernet/IP scanner communications to a Miller Auto Continumum 500
We are having an issue where during the weld we are receiving an alarm TAST-004 with a cause of IOSETRTN error has occurred. Has anyone received this alarm and what was the fix for this issue.
The problem is it doesn't happen every time. Fanuc seems to think its a feedback signal return loss.
Any suggestions would be greatly welcomed.
