6.4.3 Connection of the IEC61850 interface
The RJ45 sockets X1 and X2 serve for direct connecting Ethernet cables. Both ports are equivalent and
internally connected via a switch.
Interface: RJ45 sockets, Ethernet 100BaseTX
Mode:
10/100 MBit/s, full / half duplex, Auto-negotiation
Protocols: IEC61850, NTP
Functionality of the LED's
•
LED green: On if a network connection (link) exists, flashes during communication
6.4.4
MAC addresses
For uniquely identifying Ethernet connections in a network, to each connection a unique MAC address is
assigned. Compared to the IP address, which may be modified by the user at any time, the MAC address
is statically.
Standard Ethernet interface
IEC61850 Ethernet-Schnittstelle
6.4.5 Communication tests
Via the service menu on the device website you may check if the selected network structure is valid. The
device must be able to reach the DNS server via gateway. The DNS server then allows resolving the URL
of the NTP server to an IP address. The Standard Ethernet interface serves as interface for the
communication tests.
•
Ping: Connection test to any network device, (initial: gateway address)
•
DNS: Test, if the name resolution via DNS works (initial: URL of NTP server)
•
NTP: Test, if the selected NTP-Server is in fact a time server (stratum x)
