I'm using your Ethernet/IP driver with success on a micrologix 1400 ser. B.
Basically i just use the ReadAny function in a multithread cycle reading many tags, and write some set points.
Everything is working good but once every 2-3 days i have a strange fault on PLC that says " Major error 71h: The controller cannot communicate with the expansion I/O module. Exact module cannot be determined".
What we do is just reset the fault and it works again for 1-2 days.
It can't be because of the communication driver right ?
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:

It was a problem because of lack of suppressors on output relays…
