steady mode is ON asserted and OFF deasserted with
command 2 and vice versa with command 1.
IED commands with position and select for IEC
60870-5-103 I103POSCMD
I103POSCMD has double-point position indicators that are
getting the position value as an integer (for example, from
the POSITION output of the SCSWI function block) and
sending it over IEC 60870-5-103 (1=OPEN; 2=CLOSE). The
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
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
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).

22. 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).
The IED can be equipped with up to four short range,
medium range or long range LDCMs.
Line data communication module, short, medium and
long range LDCM
The line data communication module (LDCM) is used for
communication between the IEDs situated at a distance
<110 km/68 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 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.

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
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
battery system. An internal fail alarm output is available.
Alternative connectors of Ring lug or Compression type can
be ordered.
