About the Ethernet communication abnormality
If an Ethernet network is configured into a loop as shown below, broadcast packets are accumulated in the band, and
the communication is disabled. Therefore, do not configure the Ethernet network into a loop.
When a large amount of broadcast packets or multicast packets flow into the Ethernet network, Reader/Writers may
stop its operation. Please do not send a large amount of packet. Please separate the Reader/Writers from the network
segment that broadcast or multicast packets flow.
