Okay so I've been struggling with this problem for a while now and I cant seem to figure out a cause of it.
I use Vijeo Designer to run a troubleshoot screen for my plant's assembly lines. It talks to the many Allen Bradley PLCs we have to display information and to toggle bits and such.
We have some PLCs that seem to lose communication after a few minutes and Vijeo wont display the correct info for those PLCs.
I get an error on Vijeo that says "Fail to receive on a socket. (PLC3A)" for example. Once I get this error, I don't have comms.
There are 39 PLCs that this Vijeo project talks to and its the newest 4 PLCs that have this issue.
All the PLCs are the same type. (1756-L73 ControlLogix 5573) with version 20.12. They all have 1756-EN2T ethernet modules with various revisions, mostly 5.001. The ones having the problems are similar to ones that work.
I added some screenshots to explain what I am seeing.
