Remote Communication; Hardware Description - ABB Relion 670 series Product Manual

Line distance protection REL670 ANSI
Pre-configured
Product version: 1.2
equipment from different vendors. Disturbance files
uploading is provided.
DNP3.0 communication protocol
An electrical RS485 and an optical Ethernet port is
available for the DNP3.0 communication. DNP3.0
Level 2 communication with unsolicited events, time
synchronizing and disturbance reporting is provided
for communication to RTUs, Gateways or HMI
systems.
Multiple command and transmit
When 670 IED's are used in Substation Automation
systems with LON, SPA or IEC60870-5-103
communication protocols the Event and Multiple
Command function blocks are used as the
communication interface for vertical communication
to station HMI and gateway and as interface for
horizontal peer-to-peer communication (over LON
only).
IEC 62439-3 Parallel Redundant Protocol
Redundant station bus communication according to
IEC 62439-3 Edition 1 and IEC 62439-3 Edition 2
are available as options in 670 series IEDs. IEC
62439-3 parallel redundant protocol is an optional
quantity and the selection is made at ordering.
Redundant station bus communication according to
IEC 62439-3 uses both port AB and port CD on the
OEM module.
Select IEC 62439-3 Edition 1
protocol at the time of ordering
when an existing redundant
station bus DuoDriver installation
is extended.
Select IEC 62439-3 Edition 2
protocol at the time of ordering
for new installations with
redundant station bus.
IEC 62439-3 Edition 1 is NOT
compatible with IEC 62439-3
Edition 2.

15. Remote communication

Analog and binary signal transfer to remote end
Three analog and eight binary signals can be
exchanged between two IEDs. This functionality is
mainly used for the line differential protection.
However it can be used in other products as well.
An IED can communicate with up to 4 remote IEDs.
Binary signal transfer to remote end, 192 signals
If the communication channel is used for transfer of
binary signals only, up to 192 binary signals can be
exchanged between two IEDs. For example, this
functionality can be used to send information such
as status of primary switchgear apparatus or
intertripping signals to the remote IED. An IED can
communicate with up to 4 remote IEDs.
Line data communication module, short, medium
and long range LDCM
The line data communication module (LDCM) is
used for communication between the IEDs situated
at distances <68 miles or from the IED to optical to
electrical converter with G.703 or G.703E1 interface
located on a distances <1.9 miles away. The LDCM
module sends and receives data, to and from
another LDCM module. The IEEE/ANSI C37.94
standard format is used.
Galvanic X.21 line data communication module X.21-
LDCM
A module with built-in galvanic X.21 converter
which e.g. can be connected to modems for pilot
wires is also available.
Galvanic interface G.703 resp G.703E1
The external galvanic data communication converter
G.703/G.703E1 makes an optical-to-galvanic
conversion for connection to a multiplexer. These
units are designed for 64 kbit/s resp 2Mbit/s
operation. The converter is delivered with 19" rack
mounting accessories.
