Remote Communication; Hardware Description - Hitachi Relion 670 Series Product Manual

are available for DNP3.0 communication. DNP3.0 Level 2
communication with unsolicited events, time synchronization
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).

20. 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
The remote end data communication is used for the
transmission of analog values for line differential protection
or for the transmission of only binary signals between IEDs.
The binary signals are freely configurable and can thus be
used for any purpose, such as communication scheme
related signals, transfer trip and/or other binary signals
between IEDs.
Communication between two IEDs requires that each IED is
equipped with a Line Data Communication Module (LDCM).
The LDCM then acts as an interface to 64 kbit/s and 2Mbit/s
communication channels for duplex communication between
the IEDs. In 2Mbit/s mode, each LDCM can send and
receive up to 9 analog and up to 192 binary signals
simultaneously. In 64kbit/s mode, the LDCM can be
configured to work in either analog mode or binary mode. In
analog mode, the IED can send and receive up to 3 analog
signals and up to 8 binary signals. In binary mode, the
LDCM can send and receive only binary data (up to 192
binary signals).

Hardware modules
Numeric processing module NUM
The numeric processing module (NUM) is a CPU module
that handles all protection functions and logic.
NUM provides up to 4 optical (type LC) or galvanic (type
RJ45) Ethernet ports (one basic and three optional).
Ethernet ports can be configured as four separate or in
redundant mode PRP, HSR, or RSTP. The combination
38
supports two PRP, two HSR networks, or one RSTP
network.
Power supply module PSM
The power supply module is used to provide the correct
internal voltages and full isolation between the IED and the
M14791-3 v3
battery system. An internal fail alarm output is available.
Alternative connectors of Ring lug or Compression type can
be ordered.
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
M12449-6 v3
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
SEMOD52522-4 v10
and is used for trip output or any signaling purpose.
Static binary output module SOM
The static binary output module has six fast heavy-duty
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
The optical Ethernet module (OEM) provides two additional
optical Ethernet ports. The port connectors are of optical
IP14529-1 v1
(type LC) or galvanic (type RJ45) Ethernet ports.
M12643-3 v5
Ethernet ports can be configured as two separate or in
redundant mode PRP or HSR.
The optical Ethernet module (OEM) provides two additional
optical Ethernet ports. The port connectors are:
• SFP Optical LC
• Galvanic RJ45
