setting and disturbance file records can be
accessed using the IEC 61850 protocol.
Disturbance files are available to any Ethernet-
based application in the standard
COMTRADE format. Further, the IED can
send and receive binary signals from other
IEDs (so called horizontal communication)
using the IEC61850-8-1 GOOSE profile. The
IED meets the GOOSE performance
requirements for tripping applications in
distribution substations, as defined by the
IEC 61850 standard. The IED can
simultaneously report events to five different
clients on the station bus.
All communication connectors, except for the
front port connector, are placed on integrated
optional communication modules. The IED
can be connected to Ethernet-based
communication systems via the RJ-45
connector (100BASE-TX). If connection to a
RS-485 network is required, a 9-pin screw-
terminal connector, an optional 9-pin D-sub
connector or an optional ST-type glass-fibre
connector can be used.
Modbus implementation supports RTU, ASCII
and TCP modes. Besides standard Modbus
functionality, the IED supports retrieval of
time-stamped events, changing the active
setting group and uploading of the latest fault
records. If a Modbus TCP connection is used,
five clients can be connected to the IED
simultaneously. If required, both IEC 61850
and serial Modbus protocols can be run
simultaneously.
The IEC 60870-5-103 implementation
supports two parallel serial bus connections
to two different masters. Besides basic
standard functionality, the IED supports
changing of the active setting group and
uploading of disturbance files in IEC
60870-5-103 format.
DNP3 supports both serial and TCP modes
for connection to one master.
When the IED uses the RS-485 bus for the
serial communication, both two- and four
wire connections are supported. Termination
and pull-up/down resistors can be configured
with jumpers on the communication card so
external resistors are not needed.
The IED supports the following time
synchronization methods with a time-
stamping resolution of 1 ms:
Ethernet based:
• SNTP (Simple Network Time Protocol)
With special time synchronization wiring:
• IRIG-B (Inter-Range Instrumentation Group
- Time Code Format B)
Remote-end station time reference:
• Line differential
In addition, the IED supports time
synchronization via the following serial
communication protocols:
• Modbus
• DNP3
• IEC 60870-5-103
Remote-end station time reference:
• Line differential
