Remote Communication; Hardware Description - ABB Relion RES670 Product Manual

Phasor measurement unit RES670 2.1 IEC
IEC 62439-3 Parallel Redundancy Protocol
Redundant station bus communication according to IEC
62439-3 Edition 1 and IEC 62439-3 Edition 2 parallel
redundancy protocol (PRP) are available as options when
ordering IEDs. Redundant station bus communication
according to IEC 62439-3 uses both port AB and port CD
on the OEM module.

18. 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.
The line data communication module (LDCM) is used for
communication between the IEDs situated at distances
< or from the IED to optical to electrical converter with
G.703 or G.703E1 interface located on a distances < 3
km/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.

Hardware modules
Power supply module PSM
The power supply module is used to provide the correct
internal voltages and full isolation between the IED and
the battery system. An internal fail alarm output is
available.
Binary input module BIM
The binary input module has 16 optically isolated inputs
and is available in two versions, one standard and one
with enhanced pulse counting capabilities on the inputs
to be used with the pulse counter function. The binary
inputs are freely programmable and can be used for the
input of logical signals to any of the functions. They can
also be included in the disturbance recording and event-
recording functions. This enables extensive monitoring

and evaluation of operation of the IED and for all
associated electrical circuits.
Binary output module BOM
The binary output module has 24 independent output
relays and is used for trip output or any signaling
purpose.
Static binary output module SOM
The static binary output module has six fast static
outputs and six change over output relays for use in
applications with high speed requirements.
Binary input/output module IOM
The binary input/output module is used when only a few
input and output channels are needed. The ten standard
output channels are used for trip output or any signaling
purpose. The two high speed signal output channels are
used for applications where short operating time is
essential. Eight optically isolated binary inputs cater for
required binary input information.
mA input module MIM
The milli-ampere input module is used to interface
transducer signals in the –20 to +20 mA range from for
example OLTC position, temperature or pressure
transducers. The module has six independent,
galvanically separated channels.
Optical ethernet module OEM
The optical fast-ethernet module is used for fast and
interference-free communication of synchrophasor data
over IEEE C37.118 and/or IEEE 1344 protocols. It is also
used to connect an IED to the communication buses (like
the station bus) that use the IEC 61850-8-1 protocol
(OEM rear port A, B). The process bus use the IEC
61850-9-2LE protocol (OEM rear port C, D). The module
has one or two optical ports with ST connectors.
Galvanic RS485 serial communication module
The Galvanic RS485 communication module (RS485) is
used for DNP3.0 and IEC 60870-5-103 communication.
The module has one RS485 communication port. The
RS485 is a balanced serial communication that can be
used either in 2-wire or 4-wire connections. A 2-wire
connection uses the same signal for RX and TX and is a
multidrop communication with no dedicated Master or
slave. This variant requires however a control of the
output. The 4-wire connection has separated signals for
RX and TX multidrop communication with a dedicated
Master and the rest are slaves. No special control signal
is needed in this case.
GPS time synchronization module GTM
This module includes a GPS receiver used for time
synchronization. The GTM has one SMA contact for
connection to an antenna. It also includes an optical PPS
ST-connector output.
