Engineering Manual
• Direct point-to-point link between PCM600 and service port X1.2 on the
protection relay's LHMI or, if an LHMI is not used, the HMI port X0 of the
communication module
• Indirect link via station LAN or remotely 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 to
match the IP addresses of the physical IEDs.
4. Technical keys of the IEDs in the PCM600 project are configured to match the
technical keys of the physical IEDs.
For successful protection relay engineering and usage, the workstation firewall TCP
and UDP port configurations should be checked, especially for IEC 61850 and FTP.
Other protocols are not used for engineering or they are optional.

Setting up IP addresses

The IP address and the corresponding subnet mask can be set via LHMI for the
Ethernet interface in the protection relay. Each Ethernet interface has a default factory
IP address when the protection relay is delivered. The configured Ethernet interface
IP address is preserved if the communication card is replaced.
• Set the IP address for the protection relay's Ethernet interface and the
corresponding subnet mask via the LHMI path Configuration/
Communication/Ethernet.
