5.3 Connection to the Ethernet network
5.3.1 The integrated Ethernet switch
The device is equipped with an integrated 2 port Ethernet switch for connecting the
fieldbus technology. The following network topologies are supported:
• Tree topology
• Star topology
• Line topology
• Ring topologies (supported by device firmware version V19 and later)
INFORMATION
The number of industrial Ethernet switches connected in line impacts the telegram
runtime. If a telegram passes through the devices, the telegram runtime is delayed by
the "store-and-forward" function of the Ethernet switch:
• For a telegram length of 64 bytes by approximately 10µs (at 100 MBit/s)
• For a telegram length of 1500 bytes by approximately 130µs (at 100 MBit/s)
→ This means the more devices a telegram has to pass through, the higher the tele-
gram runtime is.
Auto-crossing
The two ports leading out of the Ethernet switch have auto-crossing functionality. You
can use both patch and crossover cables to connect to the next Ethernet node.
Auto-negotiation
The baud rate and duplex mode are negotiated by both Ethernet nodes when estab-
lishing the connection. For this purpose, both Ethernet ports of the EtherNet/IP™ con-
nection support an auto-negotiation functionality and work with a baud rate of either
100Mbit or 10Mbit in full duplex or half-duplex mode.
Notes on multicast handling
• The integrated Ethernet switch does not provide a filter function for Ethernet Mul-
ticast telegrams. Multicast telegrams are sent from the adapters (device) to the
scanners (PLC) and passed on to all switch ports.
• IGMP snooping (e.g. Managed Switches) is not supported.
INFORMATION
SEW‑EURODRIVE recommends connecting the device only with the following net-
work components:
• That support IGMP snooping (e.g. Managed Switch)
• That have protection mechanisms against high Multicast load (e.g. devices from
SEW‑EURODRIVE). Devices that do not have this function may be faulty due to
high network load.
5.3.2 Device connection–Ethernet network
The device can be connected to the Ethernet via the following Ethernet interfaces:
• X4232_11 (RJ45 connector)
