EtherNet/IP adapter dropping connection, broadcast flooding?
Hi all, looking for some advice on an industrial networking problem I'm trying to solve.
I have a RevPi Core S with a KUNBUS EtherNet/IP gateway module (PR100066) acting as an adapter/slave. The module is connected to a large flat plant network with only unmanaged switches. A PLC on the same network acts as the EtherNet/IP scanner/master.
The EtherNet/IP connection between the PLC and the KUNBUS module keeps dropping. We believe the root cause is broadcast flooding from the flat unmanaged network overwhelming the module's small network stack buffer. The module works fine in point to point scenarios but struggles in this environment.
A. Is broadcast flooding on a flat network a plausible cause for an EtherNet/IP adapter dropping its connection repeatedly?
B. Is an industrial router/firewall the right approach for this isolation, or is there a simpler solution we're missing?
Thanks in advance
