Secure communication

The protection relay supports secure communication for WHMI and file transfer
protocol using Transport Layer Security protocol. The WHMI must be connected
from a Web browser using the HTTPS protocol. File transfer client must use explicit
FTPS.

Communication services control

Ethernet ports

The protection relay allows the use of a secondary IP address for the station ports on
the communication modules COM1001...COM1003. This secondary IP network is
assigned to a single Ethernet port and can be used to make separate networks for
different communication protocols or, for example, a separate service network for
configuration purposes. Multicast station/bus communication, such as IEC 61850-9-2
LE sampled values and GOOSE, is only supported on the Network 1 interface. The
parameters for setting the secondary IP network are located under Configuration/
Communication/Ethernet/Network 2 address.
