Transformer protection RET670
Pre-configured
Product version: 1.1
61850-8-1 protocol allows intelligent devices
(IEDs) from different vendors to exchange
information and simplifies system
engineering. Peer-to-peer communication
according to GOOSE is part of the standard.
Disturbance files uploading is provided.
Serial communication, LON
Existing stations with ABB station bus LON
can be extended with use of the optical LON
interface. This allows full SA functionality
including peer-to-peer messaging and
cooperation between existing ABB IED's and
the new IED 670.
SPA communication protocol
A single glass or plastic port is provided for
the ABB SPA protocol. This allows extensions
of simple substation automation systems but
the main use is for Substation Monitoring
Systems SMS.
IEC 60870-5-103 communication protocol
A single glass or plastic port is provided for
the IEC60870-5-103 standard. This allows
design of simple substation automation
systems including 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.
Single command, 16 signals
The IEDs can receive commands either from
a substation automation system or from the
local HMI. The command function block has
outputs that can be used, for example, to
control high voltage apparatuses or for other
user defined functionality.

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).
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
and medium range LDCM
The line data communication module (LDCM)
is used for communication between the IEDs
situated at distances <60 km or from the IED
to optical to electrical converter with G.703
or G.703E1 interface located on a distances
<3 km away. The LDCM module sends and
receives data, to and from another LDCM
module. The IEEE/ANSI C37.94 standard
format is used.
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
