Bay control REC650 2.2
Product version: 2.2
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 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).

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 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).
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.
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
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
and is used for trip output or any signaling purpose.
SEMOD153688-5 v3
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.
M14791-3 v3
Serial and LON communication module (SLM) for SPA/IEC
60870-5-103, LON and DNP 3.0
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.
M16035-3 v5
Galvanic RS485 serial communication module
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 a
balanced serial communication that can be used either in 2-
wire or 4-wire connections. A 2-wire connection uses the
same signal for RX and TX and is a multidrop communication
with no dedicated Master or slave. This variant requires
