standard does not define the use of values 0 and 3.
However, when connected to a switching device, these
values are transmitted.
The BLOCK input will block only the signals in monitoring
direction (the position information), not the commands via
IEC 60870-5-103. The SELECT input is used to indicate
that the monitored apparatus has been selected (in a select-
before-operate type of control).
DNP3.0 communication protocol
SEMOD153688-5 v3
An electrical RS485 serial port, optical serial ports on the
serial communication module (SLM), optical Ethernet ports
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
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).
18. Remote communication
Line data communication module, short and medium
range LDCM
SEMOD168481-4 v11
The line data communication module (LDCM) is used for
communication between the IEDs situated at a distance <60
km/37 miles or from the IED to the optical-to-electrical
converter with G.703 or G.703E1 interface located at a
distance < 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 interface G.703 resp G.703E1
M16035-3 v5
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 operation. The converter is delivered with 19” rack
mounting accessories.
19. Hardware description
Hardware modules
IP14529-1 v1
Numeric processing module NUM
M12643-3 v5
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
supports two PRP, two HSR networks, or one RSTP
network.
Power supply module PSM
M11595-3 v6
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.
Alternative connectors of Ring lug or Compression type can
be ordered.
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.
Serial and LON communication module (SLM) for SPA/IEC
60870-5-103, LON and DNP 3.0
M14933-3 v6
The Serial and LON communication module (SLM) is used
for SPA, IEC 60870-5-103, DNP3 and LON communication.
SLM has two optical communication ports for plastic/plastic,
plastic/glass or glass/glass fiber cables. One port is used
for serial communication (SPA, IEC 60870-5-103 or DNP3
port) and the other port is used for LON communication.
Line data communication module LDCM
M16075-3 v7
Each module has one optical port, one for each remote end
to which the IED communicates.
Alternative modules are:
Short range LDCM (820 nm multi mode fiber),
Medium range (1310 nm single mode fiber)
.
Galvanic RS485 serial communication module
SEMOD158664-5 v3
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
