The communication media is always Ethernet and the used protocol is TCP/IP.
Each IED has an RJ-45 Ethernet interface connector on the front. The front Ethernet
connector shall 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.
• 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 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.
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 is 2 m. The connector type is
RJ-45.
