Communication settings

7.4.2.1 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.

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.
