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.
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

Communication fails if the IP addresses of the front and the rear port
belong to the same subnet.
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

parameter.

IED Update
The firmware update tool is used for patching the IED firmware and for adding or
replacing additional languages to the IED. Update packages are provided by Customer
Support. The update tool can be used either locally or remotely.
It is recommended to take a backup of the IED configuration before starting the
update. This can be done by using the Read from IED function from the IED context
