Function status fault protection for IEC 60870-5-103
I103FLTPROT
I103FLTPROT is used for fault indications in monitor
direction. Each input on the function block is specific for a
certain fault type and therefore must be connected to a
correspondent signal present in the configuration. For
example: 68_TRGEN represents the General Trip of the
device and must be connected to the general trip signal
SMPPTRC_TRIP or equivalent.
IED status for IEC 60870-5-103 I103IED
I103IED is a function block with defined IED functions in
monitor direction. This block uses the parameter
FunctionType; the information number parameter is defined
for each input signal.
Supervison status for IEC 60870-5-103 I103SUPERV
I103SUPERV is a function block with defined functions for
supervision indications in monitor direction. This block
includes the FunctionType parameter; the information
number parameter is defined for each output signal.
Status for user-defined signals for IEC 60870-5-103
I103USRDEF
I103USRDEF comprises function blocks with user-defined
input signals in monitor direction. These function blocks
include the FunctionType parameter for each block in the
private range, and the information number parameter for
each input signal.
Function commands for IEC 60870-5-103 I103CMD
I103CMD is a command function block in control direction
with pre-defined output signals. The signals are in steady
state, not pulsed, and stored in the IED in case of restart.
IED commands for IEC 60870-5-103 I103IEDCMD
I103IEDCMD is a command block in control direction with
defined IED functions. All outputs are pulsed and they are
NOT stored. Pulse-time is a hidden parameter.
Function commands user-defined for IEC 60870-5-103
I103USRCMD
I103USRCMD is a command block in control direction with
user-defined output signals. These function blocks include
the FunctionType parameter for each block in the private
range, and the Information number parameter for each
output signal.
Function commands generic for IEC 60870-5-103
I103GENCMD
I103GENCMD is used for transmitting generic commands
over IEC 60870-5-103. The function has two output signals,
CMD_OFF and CMD_ON, that can be used to implement
double-point command schemes.
The I103GENCMD component can be configured as either 2
pulsed ON/OFF or 2 steady ON/OFF outputs. The ON
output is pulsed with a command with value 2, while the
OFF output is pulsed with a command with value 1. If in

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
