tion functionality, for example, horizontal
communication between the IEDs, is only
enabled by the IEC 61850 communication
protocol.
The IEC 61850 communication implemen-
tation supports all monitoring and control
functions. Additionally, parameter setting and
disturbance file records can be accessed us-
ing the IEC 61850-8-1 protocol. Disturbance
files are available to any Ethernet based ap-
plication in the standard COMTRADE format.
Further, the IED can send and receive binary
signals from other IEDs (so called horizon-
tal communication) using the IEC 61850-8-1
GOOSE profile. The IED meets the GOOSE
performance requirements for tripping appli-
cations 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 com-
munication systems via the RJ-45 connector
(100BASE-TX) or the fibre-optic LC connector
(100BASE-FX). If connection to a serial bus
is required, the 10-pin RS-485 screw-terminal
or the fibre-optic ST 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 communication protocols
can be run simultaneously.
The IEC 60870-5-103 implementation sup-
ports 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 syn-
chronization 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)
In addition, the IED supports time synchroni-
zation via the following serial communication
protocols:
• Modbus
• DNP3
• IEC 60870-5-103
