Zebra EIP Communication Board RJ71EIP91

[reno]

Hello Everybody

I have started an EIP communication between a Mitsubishi IQR plc and a Zebra ZT610.
For this I use a RJ71EIP91 card for MITSUBISHI.
And on the Zebra side I had the "Network Connect" driver installed.
In the RJ71EIP91 card I put the ESD file.  (attention I was obliged to modify this one and to put the communication in "point to point" (before it was multicast)
I have a closed network (Zebra, PLC, PC)
It works. I can print labels with tags that evolve in the PLC.
The problem is that when I turn off the printer I have a lot of trouble reconnecting it to the PLC.
When I run a slave scan with the "RJ71EIP91 TOOL" software, it no longer sees the printer, although I can ping it from this software and I can see it clearly. 
To regain communication I have to reset the zebra, or initialise the network parameters, or initialise with the factory parameters. It's really strange. I can't figure out what is making me regain communication.
If I switch off the PLC or unplug the RJ45s and leave the Zebra switched on, I don't lose communication.
Do you have any ideas to help me understand my problem?
Thank you all for your help.

Sounds like a bug in the Zebra, failing to follow the requirement to close a connection on a specified number of missed packets (normally four).

Thank You 

I m will make a request to zebra.

I hope I get an answer. In fact, in all their documents it explains that Ethernet IP is only validated on Rockwell PLCs.

I haven't found the reason for the problem but on the other hand I know how to reproduce it and therefore I know how to avoid it.

 

See the files

Thanks
