EtherNet/IP Communication Module
3.5 Connections
3.5.1 RJ-45 Interfaces
The connection to ETHERNET-based fieldbuses is established via two RJ45 connectors
(see figure “RJ45 Interface, X5/X6”), also called “Western plugs,” which are connected to
the fieldbus controller via an integrated switch.
The integrated switch works in store-and-forward mode and supports 10/100 Mbit/s trans-
mission speeds, as well as full and half-duplex transmission modes, for each port.
The RJ45 sockets are wired in accordance with the specifications for 100BASE-TX.
The ETHERNET standard stipulates a twisted pair cable of at least Category 5e as a con-
necting cable. S/UTP (Screened Unshielded Twisted Pair) and STP (Shielded Twisted
Pair) type cables with a maximum segment length of 100 m can be used.
