GOOSE messaging. Analog GOOSE messaging enables fast transfer of analog
measurement values over the station bus, thus facilitating for example sharing of RTD
input values, such as surrounding temperature values, to other relay applications. The
protection relay interoperates with other IEC 61850 compliant devices, tools and
systems and simultaneously reports events to five different clients on the IEC 61850
station bus. For a system using DNP3 over TCP/IP, events can be sent to four different
masters. For systems using IEC 60870-5-103, the protection relay can be connected to
one master in a station bus with star-topology.
All communication connectors, except for the front port connector, are placed on
integrated communication modules. The protection relay is connected to Ethernet-
based communication systems via the RJ-45 connector (10/100BASE-TX) or the
fibre-optic multimode LC connector (100BASE-FX).
IEC 60870-5-103 is available from optical serial port where it is possible to use serial
glass fibre (ST connector) or serial plastic fibre (snap-in connector).
The protection relay supports the following time synchronization methods with a
timestamping resolution of 1 ms.
Ethernet communication based
• SNTP (simple network time protocol)
• DNP3
With special time synchronization wiring
• IRIG-B
IEC 60870-5-103 serial communication has a time-stamping resolution of 10 ms.
