I am currently having an issue with 2 cmore screens coming from a slc 504. The comms is feed from dh+ to ethernet by a net eni card nd from there to a startix 8000. The issue is i will randomly lose comms to the screens due to plc time out. I can connect remotely to the screens so i know they are still on the network. Also i can see they are comunicating to the stratix.
It appears they drop out going to the plc from the NetEni.
This is a random thing and the fixes for it are random as well. Sometimes i can remove the power from the cmore and it starts working again sometimes i can remove the ethernet and same thing, it works. Most of the time though we have to leave it alone and it works itself out.
I am fairly good with program debugging and troubleshooting with the plc but networking was never my strongest suit. It seems to me that i am getting packet loss/data traffic jams when communicating between the stratix/plc.

Remote connection through the ip address still works. So the cable is fine. And it is connected to the network.
The net ini is only communicating directly with the scalder screen.
(even though both of the cmore com setups are the same. They both point back to the net eni)
Basically they both are connected to the 192 network and look to the 192.168.1.4 which is the net eni/slc 504 for information.

This is the email my coworker on days sent me concerning it. I know the stratix shouldn't be an issue as every plc in each electric room(8 in total) has this set up and this is the only 2 screens that act like this.

I fight the same problem you are describing, I described my problem to a Rockwell instructor a couple weeks ago, He didn't have any good advice for me other than to say that he thought was probably being caused by our SLC 5/05's and the way they handle data.
Sometimes it will communicate trouble free for months at a time, then we will have a bad week where it locks up daily. It's So Random.
We changed the way our messages were being done, it helped minimally.

Well my day time counter part did some digging. It seems the correct fix for is to just power cycle the NetEni device. Hopefully this will help out others with the same issue
