ABB RELION RET670, Commissioning Manual, Page: 54 / 328

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. The front port can
be seen as a service 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 or,
• 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/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.
