Remote Communication; Hardware Description - ABB RELION 670 Series Product Manual

Bay control REC670 2.1 IEC
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 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.

17. 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
<110 km/68 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.

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.

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
