System concept Device family
3 System concept
3.1 Device family
The EDS500 device family has been designed as multilayer switch and multi-purpose
communication device specifically for tasks of the process data communication. The devices
are employed for the data communication in future-oriented energy networks, for remote
meter reading, remote monitoring and control when feeding renewable energy into Smart
Grids.
The device have
•
four Ethernet interfaces (IEEE 802.3) for LAN connections.
•
Up to two SHDSL interfaces for data transmission via 2-wire-copper for distances up to 25
km with transmission rates between 192 and 15.000 kbps.
•
Up to two pluggable optical transceivers for communication via optical fibre in SFP design
(small formfactor pluggable) for an easy installation of various transceivers and distances
of up to 180 km at 100 Mbps.
•
up to 2 serial interfaces for configuration and / or for transmission of serial remote access
protocols.
The devices feature extensive management tools for telecontrol like Syslog, SNMP, SSH,
Telnet, IEC 60870-5-104 and an integrated web-server for easy configuration as well as
comprehensive self monitoring functions to monitor the signal quality on copper cables and
optical lines as well as the device status.
High availability operation is possible as redundant structures like rings or parallel routes can
be set up.
These features cut out the EDS500 devices as the ideal communications technology for
telecontrol technology e.g. according to IEC 60870-5-104, IEC 60870-5-101 or IEC 61850. Old
copper networks become high performance IP networks with telecontrol and redundant
protection. In a mixed operation it is possible to keep the old telecontrol technology while
adding modern technology step by step (TCP/IP based transmission, VoIP phones).
The compact housing without any moving parts for easy mounting on hat rails, a wide range
power supply (24 to 60 V DC), low power consumption, an enhanced temperature range and
integrated overvoltage protection prove the concept of the EDS500 devices.

The monitoring function of the EDS500 devices allows to monitor the network to the central
office. Failure of the primary connection (here: VPN tunnel through the internet) makes the
EDS500 device in station 4 to start a dial-in connection via the mobile network as secondary
connection. Placing the dial-in spots at the end of a line leads not only to a line protection
when the VPN tunnels is lost, but also for any loss of connection between the stations 1 to 4.
3.3 Functions overview
3.3.1 Remote control protocols and protocol integration
As EDS500 devices support TCP/IP based protocols like IEC 60870-5-104 as well as the
established RS-232 based serial protocols like IEC 60870-5-101 it is possible to transport
these (and other) protocols in the same network simultaneously. This mixed operation allows
to modernize existing SCADA networks step by step with the future-proof IP technology.
Numerous established serial protocols can be transported with this method among others
IEC 60870-5-101, Modbus, RP570/571, SEAB-1F and many more.
Using serial tunnelling improves existing serial networks with the advantages of packet
oriented IP networks: protection with redundant connections (rings, backup connections),
control and monitoring as well astransmission via modern DSL connections or optical
connections.
The devices support native IEC 60870-5-101 and IEC 60870-5-104 which cuts them out for the
future oriented, step-by-step expansion during the network modernization: The integrated
conversion function from IEC 60870-5-101 to IEC 60870-5-104 and back allows the use
of a modern IEC-104 based central office and switching the network to packet oriented
IP transmission technology while the existing IEC-101-RTUs can still be used due to the
conversion function. The transmission technology would already exist if these RTUs shall be
replaced with modern IEC 60870-5-104 devices.
Due to the integrated IEC 60870-5-104 support of EDS500 devices the communications
technology can be monitored directly from a IEC 60870-5-104 central office.
1KGT150966 V0001 15
Functions overview System concept
Serial protocols that use the RS-232 interface can be transported via IP networks with the
help of EDS500 devices. The serial data stream gets converted into individual packets and
sent to one or more counter parts that re-assemble the packets into a serial data stream. To
avoid data loss due to packet loss, a error correcting protocol can be activated.
3.3.2 Monitor and interface dependencies
The EDS500 devices support the monitoring of an arbitrary device when the IP address is
known. Alternatively, entries in the routing table can be monitored.
This function is called monitor.
The monitor checks periodically the availability of a certain IP address on the basis of the
response to ICMP echo request packages (ping). The query interval can be set.
With the help of the interface dependency function port states can be linked or reversely
linked to other port states or the monitor (Link Fault Pass Through). If e.g. the primary
connection should fail, then a secondary connection can be established with a dial-up
modem.
3.3.3 Switching and Spanning Tree
The primary application of EDS500 devices is that of a (Layer 2) switch. As the devices not
only operate on the layer 2 of the OSI layer model but can also deal with data of the routing
layer 3 they are also called multilayer switches.
In the operation mode of a layer 2 switch the device handles incoming Ethernet frames by
forwarding them to certain ports in correlation to a target address. While doing so, the so-
called MAC table of the device learns the sender address. Ethernet frames with known target
addresses are forwarded only to those ports for which is known that the target address
can be found beyond them. Such a network can be expanded in a self-learning way. An
automatic aging process makes sure that once learned network structures can be modified
and removed.
To avoid that invalid replication of Ethernet frames brings the network to a standstill (so-
called broadcast storms), it has to be taken care of a loop-free operation without active
parallel routes. For this the EDS500 devices implement the Spanning-Tree-, Rapid-Spanning-
Tree-, Multiple-Spanning-Tree-Protocol (IEEE 802.1D-2004 and IEEE 802.Q-2011) and ERPS
protocol(ITU-T G.8032). These protocols are capable to enable or disable redundant paths if
required as they create one or more logical trees so that only one route leads to each target.
3.3.4 Virtual local Networks (VLANs)
VLANs are the option to split one physical network into several logical networks. Using this
feature it is possible to create network segments without additional hardware.
The EDS500 devices support VLANs according to standard IEEE 802.1Q.
For example, two networks can be connected isolated from each other using the same
infrastructure: RTUs and IP telephones can't see each other. Access ports and trunk ports
have to be differentiated. Access ports form the outer edge of the VLAN infrastructure
whereas the trunk ports connect the VLAN components (switches).
16 1KGT150966 V0001
System concept Functions overview
3.3.5 IP routing
The EDS500 devices support routing on IP level (layer 3 of the OSI layer model) to create or
participate in a routed environment.
The EDS500 devices use the Routing Information Protocol (RIPv2, RFC2453) to automatically
create routing tables and synchronization. Classless Inter-Domain Routing (CIDR) is
supported. The extensions Triggered Updates and Split Horizon grant in general switching
times of less than a second when the topology is changed.
3.3.6 SNMP
The Simple Network Management Protocol is a network protocol to remotely monitor and
control network devices. A central office can request the runtime parameters and signal
deviations from the ordinary state. The protocol can be read by machines and is transmitted
in code as opposed to e.g. the Syslog protocol that sends messages as plain text. SNMP
packets are (usually) transmitted via UDP/IP.
The devices of the EDS500 series implement SNMP in the versions SNMPv1 (RFC 1155, RFC
1156, RFC 1157), SNMPv2c (RFC 1901, RFC 1905, RFC 1906) and SNMPv3 (RFC 3410).
Contents and extent of the objects (OIDs) that can be accessed with SNMP is defined by
several MIB modules (Management Information Base). They are standardized and consist of:
MIB-2 (SNMPv2- MIB, RFC 3418), Bridge MIB (RFC 4188), Interface MIB (RFC 2863), IP MIB (RFC
4293), TCP MIB (RFC 4022), UDP MIB (RFC 4113), LLDP-MIB (IEEE-802.1AB) andENTITY-MIB
(RFC 6933). Also, EDS500 devices use a manufacturer-proprietary MIB (ABB-EDS500-MIB),
with objects that allow enhanced device management and detailed access to internal
parameters. The ABB-EDS500-MIB file is available on request.
3.3.7 Syslog
Syslog is a network protocol to transmit log entries in an IP network. The transmission usually
uses UDP/IP and consists of human readable plain text messages including information
about severity and a times tamp.
The EDS500 devices have a log filer on the devices themselves. If a SNTP server (Simple
Network Time Protocol) has been set, then the time stamp is a real date, otherwise it shows
the system up time. In addition, log entries can be sent to a central Syslog server at the time
of the event. The EDS500 devices use a numbered Syslog message scheme so that missing
messages can be detected.
3.3.8 Alarm System
The EDS500 devices have a three-level alarm model.
The alarm model distinguishes between the following levels:
•
Notice,
•
Warning,
•
Alarm.
If an event happens that triggers an alarm then it creates a log entry and optionally sends a
Syslog message.
1KGT150966 V0001 17
Functions overview System concept
For the critical level Alarm, a relais is switched that can control a signalization device. Unlike
spontaneous events that do not lead to an alteration of the operational state, alarms are
triggered by events that, while they prevail, modify the operational state.
The levels indicate the degree of limitation for operation that is caused by the event. For
some events, the administrator can set the alarm level, others are fixed.
For more information: EDS500 Manual - Part 2: Alarms and alarm configuration.
3.3.9 SSH-Telnet console
Devices of the EDS500 series offer an SSH server and Telnet server to access a command
interpreter. Telnet is a network protocol to access the console of a remote device, SSH offers
additionally an encrypted connection. Both protocols are transported via TCP/IP.
The command interpreter of the EDS500 series translates user input into device settings.
There are different access levels. The view mode allows to view information and monitor
parameters. It is a read-only mode. The operation mode "configuration" has full access to the
system to modify the configuration and retrieve all system details.
3.3.10 Web interface
As an alternative to the command line oriented access method of the command interpreter
the web server of the EDS500 devices offers a comfortable user-interface. With an existing
IP connection to a device it can be configured and monitored fully using an ordinary web
browser.
3.3.11 RADIUS
RADIUS (Remote Authentication Dial-In User Service) is a network protocol to authenticate
logins. The RADIUS server runs as a central service e.g. in the central office. If you want to
connect to an arbitrary device, user name and password are sent to the RADIUS server that
