Outgoing MSG from PLC5 to ControlLogix

I try to send outgoing MSG from PLC5 to ControlLogix via DigiOne IAP. The reverse operation work well but I’m not able to send message from PLC5.

I have a Digi one IAP connected to PLC5 on Port 0 and want to send MSG over Ethernet on a ControlLogix in slot 0.

I configure as detailled in “Setting up DigiOne-IAP for Rockwell Bridging” and bocl MSGalway timeout.

With Wireshark, I saw the outgoing communication from the Digi to the Logix and it fail on “Path Destination Unknown: PCCC Class - Execute PCCC[Malformed Packet]”

Any hint about that^
