• Set the same communication speed (100Mbps) for the master station and local stations.
• 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 device stations with different communication
speeds of 1Gbps and 100Mbps coexist on the end side via the industrial switch. The communication will be enabled by
configuring settings with the industrial switch 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 device station with 100Mbps.
