REC615 and RER615 Engineering Manual

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.

Note: The protection relay's front port IP address is fixed to “192.168.0.254” and it cannot be modified.
Set the IP address for the protection relay's rear port and the corresponding subnet mask via the LHMI path Configuration > Communication > Ethernet > Rear port.
Table 1. Default IP address for the rear port and the corresponding subnet mask
IP address Subnet mask
192.168.2.10 255.255.255.0
Note: Communication fails if the IP addresses of the front and the rear port belong to the same subnet.
Note: When using redundant Ethernet (HSR or PRP), configure all devices in the network before connecting cables to ports LAN A and LAN B. Avoid using the LAN A or LAN B ports on redundant communication modules while changing the Switch mode parameter.
