Section 4
Setting up a project
Each IED has an Ethernet interface connector on the front and on the rear side. The Ethernet
connector can be used for communication with PCM600.
When an Ethernet-based station protocol is used, PCM600 communication can use the same
Ethernet port and IP address.
For the connection of PCM600 to the IED, two basic variants have to be considered.
• Direct point-to-point link between PCM600 and the IED front port.
• Indirect link via a station LAN or from remote via a network.
The physical connection and the IP address must be configured in both cases to enable
communication.
The communication procedures are the same in both cases.
1. If needed, set the IP address for the IEDs.
2. Set up the PC or workstation for a direct link (point-to-point), or
3. Connect the PC or workstation to the LAN/WAN network.
4. Configure the IED IP addresses in the PCM600 project for each IED to match the IP addresses
of the physical IEDs.
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 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/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.
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 null-modem cables
or cross-wired cables. The maximum length should be about 2 m. The connector type is RJ-45.
22
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.
