Naming convention to identify protection relays
The protection relay name must be unique within the planned network. A default name is
applied if it is not specified by the client and it is based on the reference designation system
of IEC 61346

IP address allocation
The IP address is a number that identifies a network device. Each device connected to a net-
work must have a unique address. The default IP address range for a substation is: 172.16.X.X -
172.30.X.X. The IP addresses and IP masks are a specific feature of each device. In case of
device failure, the replacement device receives the same IP address. The IP address should be
structured in a way to reflect the physical plant layout according to IEC 61850-90-4.
