INFORMATION
• According to IEC 802.3, the maximum cable length for 10/100 MBaud Ethernet
(10BaseT/100BaseT), e.g. between 2network stations, is 100m.
• SEW‑EURODRIVE recommends that you do not directly connect third-party end
devices to the DHR21B/41B option in order to minimize the load on the end
devices in EtherNet/IP networks caused by undesired multicast data traffic. Con-
nect devices from third-party manufacturers via a network component that sup-
ports the IGMP snooping functionality (e.g. managed switch). Managed switches
with IGMP snooping functionality are not required for PROFINETIO and Modbus/
TCP networks.
Connection type
To connect DHR21B/41B to the Ethernet network, connect Ethernet interface X30-1
or X30-2 (RJ45 plug connector) to the other network stations using a category5,
classD twisted-pair cable in accordance with IEC11801 edition2.0. The integrated
switch assists you in implementing a line topology and provides auto-crossing func-
tions.
