Remote Communication; Analog And Binary Signal Transfer To Remote End; Binary Signal Transfer To Remote End, 192 Signals; Binary Input/Output Module Iom - ABB RET670 Product Manual

Transformer protection RET670 2.0
Product version: 2.0
with unsolicited events, time synchronizing and disturbance
reporting is provided for communication to RTUs, Gateways or
HMI systems.
Multiple command and transmit
When IEDs are used in Substation Automation systems with
LON, SPA or IEC 60870-5-103 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 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.
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/37 miles 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.
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.

19. Hardware description

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.
Serial and LON communication module SLM, supports
SPA/IEC 60870-5-103, LON and DNP 3.0
The serial and LON communication module (SLM) is used for
SPA, IEC 60870-5-103, DNP3 and LON communication. The
module has two optical communication ports for plastic/plastic,
plastic/glass or glass/glass. One port is used for serial
