The following five option cards are available:
• The Fibre-Optic Option Card SFIBER pro vides three fibre-optic transceiver pairs for
the interconnection of bay level devices,connection between two RER 111 modules
equipped with Fibre-Optic Option Cards or between a RER 111 module and higher
level devices e.g. MicroSCADA.
• The RS-485 Option Card SRS485 provides a means of connecting LON bus
devices using the RS-485 interface to the LonWorks network. The card also com
prises a fibre-optic transceiver pair.
• The SLTA Option Card SSLTA provides the interconnection between higher level
devices (e.g. monitoring terminals, PC, etc.) and the LonWorks network.
It can also provide the interconnection between RER 111 modules by using the fibre-optic
transceiver pair.
• The Router Option Card, SROUT, provides connection to devices using twisted
pair (TP/XF-78 or TP/XF-1250) transceiv ers and / or using fibre-optic transceiver
pairs. It also provides a means by which an overall system can be divided into multiple
subsystems.
• The Double Connection Option Card SREDU provides a means for connecting
devices together by using double connec tions. This method enables the use of two
fibre-optic transceiver pairs to connect to any device supporting double connection.
In the event of a fault in one fibre-optic connection, this connection is still able to
receive and transmit data to devices.
• The LON Clock Master option card SLCM provides means for connection to a clock
reference device and performs time synchronization on LON.There are five sepa
rate time synchronization methods for different types of bay level devices and for
different accuracy requirements. The SLCM option card includes an internal
clock to generate various synchronization messages and signals in order to synchro
nize other devices on the LON network.
The Lon Star-Coupler RER 111 is used to interconnect the nodes in a LonWorks net
work. It offers a variety of configuration options. As standard the RER 111 unit pro
vides the following:
• Single or double auxiliary power supply units with input voltage ranges 80…265 V
ac/dc or 18…80 V dc
• Input/Output (I/O) Card
• Mother Board
• 9 slot placements for option cards

Tools
The protection relay is delivered as a preconfigured unit. The
default parameter setting values can be changed from the front
panel user interface (local HMI), the Web browser-based user
interface (Web HMI) or Protection and Control IED Manager
PCM600 in combination with the relay-specific connectivity package.
PCM600 offers extensive relay configuration functions. For
example, depending on the protection relay, the relay signals,
application, graphical display and single-line diagram, and IEC
61850 communication, including horizontal GOOSE
communication, can be modified with PCM600.
When the Web HMI is used, the protection relay can be
accessed either locally or remotely using a Web browser
(Internet Explorer). For security reasons, the Web HMI is
enabled by default but it can be enabled via the local HMI. The
Web HMI functionality can be limited to read-only access.
The relay connectivity package is a collection of software and
specific relay information, which enables system products and
tools to connect and interact with the protection relay. The
connectivity packages reduce the risk of errors in system
integration, minimizing device configuration and setup times.
Further, the connectivity packages for protection relays of this
product series include a flexible update tool for adding one
additional local HMI language to the protection relay. The
update tool is activated using PCM600. and it enables multiple
updates of the additional HMI language, thus offering flexible
means for possible future language updates.
Selection and ordering data
The relay type and serial number label identifies the protection
relay. The label is placed above the local HMI on the upper part
of the plug-in-unit. An order code label is placed on the side of
the plug-in unit as well as inside the case. The order code
consists of a string of letters and digits generated from the
relay’s hardware and software modules.
Relay case and plug-in unit
The relay cases are assigned to a certain type of plug-in unit.
For safety reasons, the relay cases for current measuring relays
are provided with automatically operating contacts for short
circuiting the CT secondary circuits when a relay unit is
withdrawn from its case. The relay case is further provided with
a mechanical coding system preventing the current measuring
relay units from being inserted into relay cases intended for
voltage measuring relay units.

Mounting methods
By means of appropriate mounting accessories, the standard
relay case can be flush mounted, semi-flush mounted or wall
mounted. The flush mounted and wall mounted relay cases can
also be mounted in a tilted position (25°) using special accessories.
Further, the relays can be mounted in any standard 19”
instrument cabinet by means of 19” mounting panels available
with cut-outs for one or two relays.Alternatively, the relays can
be mounted in 19” instrument cabinets by means of 4U
Combiflex equipment frames.
For routine testing purposes, the relay cases can be equipped
with test switches, type RTXP 18. which can be mounted side
by side with the relay cases.
When the relay is in the remote mode, it can execute
commands sent from a remote location. The relay supports the
remote selection of the local/remote mode via a binary input.
This feature facilitates, for example, the use of an external
switch at the substation to ensure that all relays are in the local
mode during maintenance work and that the circuit breakers
cannot be operated remotely from the network control center.
Local HMI
The relay is equipped with a four-line liquid crystal display.
Depending on the chosen font and language, the number of
visible lines may vary. The display is designed for entering
parameter settings of the protection and control functions. It is
also suited for remotely controlled substations where the relay
is only occasionally accessed locally via the front panel user interface.
The display offers front-panel user interface functionality with
menu navigation and menu views. Depending on the
configuration, the relay displays the related measuring values.
The local HMI includes a push button (L/R) for local/remote
operation of the relay. When the relay is in the local mode, it can
be operated only by using the local front-panel user interface.
When the relay is in the remote mode, it can execute
commands sent from a remote location. The relay supports the
remote selection of the local/remote mode via a binary input.
This feature facilitates, for example, the use of an external
switch at the substation to ensure that all relays are in the local
mode during maintenance work and that the circuit breakers
cannot be operated remotely from the network control center.
The IEC 61850 standard specifies network redundancy which
improves the system availability for substation communication.
The network redundancy is based on two complementary
protocols defined in the IEC 62439-3 standard: PRP and HSR
protocols. Both the protocols are able to overcome a failure of a
link or switch with a zero switch-over time. In both the
protocols, each network node has two identical Ethernet ports
dedicated for one network connection. The protocols rely on
the duplication of all transmitted information and provide a zero
switch-over time if the links or switches fail, thus fulfilling all the
stringent real-time requirements of substation automation.
In PRP, each network node is attached to two independent
networks operated in parallel, thus providing zero time recovery
and continuous checking of redundancy to avoid failures. The
networks are completely separated to ensure failure
independence, and can have different topologies.
The relay can send binary and analog signals to other devices
using the IEC 61850-8-1 GOOSE (Generic Object Oriented
Substation Event) profile. Binary GOOSE messaging can be
employed, for example, for protection and interlocking-based
protection schemes. The relay meets the GOOSE performance
requirements for tripping applications in distribution
substations, as defined by the IEC 61850 standard (<10 ms
data exchange between the devices).
For redundant Ethernet communication, the relay offers two
galvanic Ethernet network interfaces. A third port with galvanic
Ethernet network interface is also available providing
connectivity for any other Ethernet device to an IEC 61850
station bus inside a switchgear bay, for example connection of
a remote I/O. Ethernet network redundancy can be achieved
using the high-availability seamless redundancy protocol (HSR)
or the parallel redundancy protocol (PRP) or with a self-healing
ring using Rapid Spanning Tree Protocol (RSTP) in managed
switches. Ethernet redundancy can be applied to Ethernet
based IEC 61850 and Modbus protocols.
