EtherNet/IP Scanner of codesys with Ctrlx Core - connection failure errors

Hello,

our customer has defined an EtherNet/IP scanner on Port X51 of ctrlx Core using the Codesys communication App.

we noticed during cycle, that we have many connections failures on the communication,

the customer has 2 EtherNet/IP Slaves, with excatly the same behavior,

I'm able to reproduce it using XM21 as EtherNet/IP Slave.

we used both 1.12.9 release, and 1.16.1

codesys EtherNet/IP App version : 4.2.0.0

do you have more information about this issue ?

Hello,

we found out that the behavior depends on the Ethernet IP stack that is implemented on the individual device. This is the explanation, why this works for running the adapter on the onboard Ethernet or the XFE. The issue is addressed to th edevelopment team.

kind regards
