Section 8
Editing the network settings
The communication media is always Ethernet and the used transport layer is TCP/IP.
Each IED has an RJ-45 Ethernet interface connector on the front. The front Ethernet connector is
recommended to 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.
To connect PCM600 to the IED, two basic variants must be considered.
• Direct point-to-point link between PCM600 and the IED front port.
• A 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
Communication between the IED and PCM600 is enabled from the LHMI. The IP address and the
corresponding communication subnetwork mask must be set via the Ethernet configuration tool
(ECT) for each available Ethernet interface in the IED. Each Ethernet interface has a default factory
IP address when the IED is delivered. The IP adress and the subnetwork mask might have to be
reset when an additional Ethernet interface is installed or an interface is replaced.
DHCP is available for the front port, and a device connected to it can thereby obtain an
automatically assigned IP address via the local HMI path Main menu/Configuration/
Communication/Ethernet configuration/Front port/DHCP.
Alternatively 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/ETHFRNT:1Main menu/Configuration/
Communication/Ethernet configuration/AP_FRONT.
Setting up the PC or workstation for point-to-point access to IEDs front
port
An ethernet cable (max 2 m length) with RJ-45 connectors is needed to connect two physical
Ethernet interfaces together without a hub, router, bridge or switch in between.
1. Select Search programs and files in the Start menu in Windows.

If an IED is equipped with optical LC interface, a converter between RJ-45 and LC is
needed.
