• When "Communication Mode" is set to "Multicast" and the communication speed of the master station is 1Gbps,
communication may not be possible depending on the type of the device if slave stations with different communication
speeds of 1Gbps and 100Mbps coexist on the end side via the switching hub. The communication will be enabled by
configuring settings with the switching hub so that the multicast frame (with multicast MAC address 09:00:70:00:10:02 and
09:00:70:00:10:05) will not be transferred to the port of the slave station with 100Mbps.
