address when the IED is delivered. This is not given when an additional Ethernet
interface is installed or an interface is replaced.
• The default IP address for the IED front port is 10.1.150.3 and the corresponding
subnetwork mask is 255.255.255.0, which can be set via the local HMI path
Main
menu/Configuration/Communication/TCP-IP configuration/1:ETHFRNT .
• The default IP address for the IED rear port is 192.168.1.10 and the corresponding
subnetwork mask is 255.255.255.0, which can be set via the local HMI path
Main
menu/Configuration/Communication/TCP-IP configuration/1:ETHLAN1 and
Rear OEM - port CD .
The front and rear port IP addresses cannot belong to the same subnet
or communication will fail. It is recommended to change the IP address
of the front port, if the front and rear port are set to the same subnet.

port
A special cable is needed to connect two physical Ethernet interfaces together without
a hub, router, bridge or switch in between. The Tx and Rx signal wires must be crossed
in the cable to connect Tx with Rx on the other side and vice versa. These cables are
known as cross over cables. The maximum length should be about 2 m. The connector
type is RJ-45.

The following description is an example valid for standard PCs using Microsoft
Windows operating system. The example is taken from a Laptop with one Ethernet
interface.
Administrator rights are required to change the PC communication
setup. Some PCs have the feature to automatically detect that Tx
signals from the IED are received on the Tx pin on the PC. Thus, a
straight (standard) Ethernet cable can be used.
