Setting up IP addresses
The IP address and the corresponding mask must be set via the LHMI for each
available Ethernet interface in the IED. Each Ethernet interface has a default
factory IP 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/Settings/General settings/Communication/
Ethernet configuration/Front port
.
•
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/Settings/General settings/Communication/
Ethernet configuration/Rear OEM - port AB
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.
Setting up the PC or workstation for point-to-point access to IEDs
front 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
