18. Station communication

The IED supports a range of communication
protocols including IEC 61850, IEC 60870-5-103,
®
Modbus and DNP3. Operational information and
controls are available through these protocols.
However, some communication functionality, for
example, horizontal communication between the
IEDs, is only enabled by the IEC 61850
communication protocol.
The IEC 61850 communication implementation
supports all monitoring and control functions.
Additionally, parameter settings, disturbance
recordings and fault records can be accessed
using the IEC 61850 protocol. Disturbance
recordings are available to any Ethernet-based
application in the standard COMTRADE file
format. The IED supports simultaneous event
reporting to five different clients on the station
bus.
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 offers an optional second Ethernet bus to
enable the creation of a self-healing Ethernet ring
topology. The communication module including
two galvanic RJ-45 ports enables the creation of
a cost efficient communication ring using CAT5
STP cables and a managed switch with (RSTP)
support. The managed switch controls the
consistency of the loop, routes the data and
corrects the data flow in case of a communication
disturbance. The IEDs in the ring topology act as
unmanaged switches forwarding unrelated data
traffic. The Ethernet ring solution supports the
connection of up to thirty 615 series IEDs. If more
than 30 IEDs are to be connected, it is
recommended that the network is split into
several rings with no more than 30 IEDs per ring.
The self-healing Ethernet ring solution avoids
single point of failure concerns and improves the
reliability of the communication. The solution can
be applied for the Ethernet-based IEC 61850,
Modbus and DNP3 protocols.
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.
