ABB REQ650 Product Manual - page 19
The LHMI is used for setting, monitoring and controlling.
12. Basic IED functions
Time synchronization
M11344-3 v9
The time synchronization function is used to select a common
source of absolute time for the synchronization of the IED
when it is a part of a protection system. This makes it
possible to compare events and disturbance data between all
IEDs within a station automation system and in between sub-
stations.
13. Station communication
Communication protocols
M14815-3 v12
Each IED is provided with a communication interface,
enabling it to connect to one or many substation level
systems or equipment, either on the Substation Automation
(SA) bus or Substation Monitoring (SM) bus.
Available communication protocols are:
• IEC 61850-8-1 communication protocol
• LON communication protocol
• SPA or IEC 60870-5-103 communication protocol
• DNP3.0 communication protocol
Several protocols can be combined in the same IED.
IEC 61850-8-1 communication protocol
M14787-3 v13
The IEC 61850-8-1 communication is also possible from the
electrical Ethernet front port. IEC 61850-8-1 protocol allows
intelligent electrical devices (IEDs) from different vendors to
exchange information and simplifies system engineering. IED-
to-IED communication using GOOSE and client-server
communication over MMS are supported. Disturbance
recording file (COMTRADE) uploading can be done over MMS
or FTP.
The front port shall not be used due to
interference.
LON communication protocol
SEMOD120140-5 v2
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 the IEDs.
SPA communication protocol
SEMOD120134-5 v1
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
SEMOD120137-5 v3
DNP3.0 communication protocol
SEMOD153688-5 v1
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
M14791-3 v3
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
GUID-A90FDBA7-D4D7-4CBD-9F05-13DCC9971779 v5
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.
14. Hardware description
Hardware modules
IP14529-1 v1
Power supply module PSM
M11595-3 v5
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
M1769-3 v4
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
M6938-3 v4
The binary output module has 24 independent output relays
and is used for trip output or any signaling purpose.
Binary input/output module IOM
M6939-3 v6
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.
