18. Communication
The IED supports the IEC 61850 substation
automation standard including horizontal
GOOSE communication as well as the well-
established DNP3 (TCP/IP) and IEC
60870-5-103 protocols. All operational
information and controls are available
through these protocols.
Disturbance files are accessed using the IEC
61850 or IEC 60870-5-103 protocols.
Disturbance files are also available to any
Ethernet based application in the standard
COMTRADE format. The IED can send binary
signals to other IEDs (so called horizontal
communication) using the IEC 61850-8-1
GOOSE (Generic Object Oriented Substation
Event) profile. Binary GOOSE messaging can,
for example, be employed for protection and
interlocking-based protection schemes. The
IED meets the GOOSE performance
requirements for tripping applications in
distribution substations, as defined by the
IEC 61850 standard. Further, the IED
supports the sending and receiving of analog
values using 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 IED
applications. The IED interoperates with
other IEC 61850 compliant IEDs, 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 IED 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 IED 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 IED supports SNTP, DNP3 and IRIG-B
time synchronization methods with a time-
stamping resolution of 1 ms.
