factory IP address when the complete 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 255.255.0.0, 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 requested 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 null-modem cable or cross-wired cable. The
maximum length should be about 2 m. The connector type is RJ-45, see
IED
IEC09000096 V1 EN
Figure 44: Point to point link between IED and PCM600 using a null-modem
cable
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 requested 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
straight (standard) Ethernet cable can be used.
