Each protection relay has an Ethernet interface connector on the front and optionally
on the rear side as well. The Ethernet connector can be used for communication with
PCM600.
When an Ethernet-based station protocol is used, the same Ethernet port and IP
address can be used for PCM600 communication.
Two basic variants have to be considered for the connection between PCM600 and the
protection relay.
•
Direct point-to-point link between PCM600 and the protection relay's front port
•
Indirect link via station LAN or from remote via network
1. If needed, the IP address for the protection relay is set.
2. A PC or workstation is set up for a direct link (point-to-point), or the PC or
workstation is connected to the LAN/WAN network.
3. The protection relays' IP addresses in the PCM600 project are configured for each
protection relay to match the IP addresses of the physical IEDs.
4. Technical keys of the IEDs in PCM600 project are configured for each protection
relay to match the technical keys of the physical IEDs.
For successful protection relay engineering and usage, check the workstation firewall
TCP and UDP port configurations, especially for IEC 61850 and FTP. Other protocols
are not used for engineering and/or they are optional.

Setting up IP addresses
The IP address and the corresponding subnet mask can be set via LHMI for the rear
Ethernet interface in the protection relay. Each Ethernet interface has a default factory
IP address when the complete protection relay is delivered. The configured rear port
IP address is preserved if a new communication card with Ethernet is installed or the
communication card is replaced.
