Started by bboytaktix1 May Posted 1 May edited. Good afternoon fellow members, I once again ask for your help to know if any of you have struggled with similar issues. We have in the rack a EN2T card revision 3.

As this happened over the weekend, the local electrician was called and he tried cycling power to the rack and there was no change after it came back on not sure how long he left power off to the rack though. The problem seemed to be fixed after we told him to pull the EN2T card out of its slot and then re-insert it.


We verified the CIP cinnections for this card and it is around 98 to CIP connections out of a max ofso not too high. EN2T Card is set to auto-negociate, just like all the other cards we use at all of our plants.

Intermittent communication loss with rack/PLC

Has anyone ever experienced a similar problem? Thank you in advance for all your help and knowledge-sharing! Posted 2 May With intermittent communication issues, put on your detective hat and dig into the System-side how is the network built, what devices 1756e-n2t on the network and the Bonding-side what are the ground bonding methods. Your EN2T communication module could be getting hammered with network transactions that it suffers an early death.

Have you installed WireShark and observed your network to see what traffic is going on? You could also have poor bonding practices combined with intermittent ground noise that could be leading to premature failure of the EN2T communication module. Yes, I have had new machine a,len that function great until they are put on a customer’s floor, and then the problems arise with system communication.
