System concept Device family
3 System concept
3.1 Device family
The 500FSD series out of the EDS500 product family is a product series of ruggedized FSK-
based analog modems. It is especially designed to support critical infrastructure companies
by enabling communication for traditional serial devices like RTUs or IEDs. The 500FSD
product series interoperates with any standard FSK-based technology but is also capable
to achieve higher data rates by enhanced technology. The devices are used in a variety of
markets which require the need for cost-efficient reliable communication.
The following table shows the technical features of the FSK modems.

Functions overview System concept
3.2 Functions overview
3.2.1 Applications
The wide area of applications enable the EDS500 series - FSK modems to be used in any cost-
efficient environment using serial communication. Its simplicity and robustness provide ease
of installation as well as long product lifetime.
Analog serial modems of the EDS500 series allow to implement real physical two-or-four wire
shared bus topologies (all modems connect to the same cable) with ranges of up to 30 km.
The compact case without moveable parts for easy installation on DIN rail, a wide range
power supply (24…60 V) with small power consumption, extended temperature range and
integrated overvoltage protection complete the concept of the EDS500 series - FSK modems.
3.2.2 Connectivity
The EDS500 series of analog modems consists of multiple products allowing to establish
wide area connections via customer-owned copper cables. The devices provide a serial
interface (V.24 / RS-232) and a combined two-/four-wire line interface.
A variety of communication schemes are supported to provide connectivity to clients and
other communication devices:
•24 channels each 50 bps (ITU-T/CCITT R.35)
•12 channels each 100 bps (ITU-T/CCITT R.37)
•6 channels each 200 bps (ITU-T/CCITT R.38a)
•2 channels each 600 bps
•1 channel 1200 bps (ITU-T/CCITT V.23)
•1 channel 2400 bps
•1 channel 9600 bps
500FSD devices can be used in point-to-point (end-to-end) and multidrop (partyline)
applications. The transmission is transparent, supporting byte oriented (e.g. IEC 60870-5-101,
IEC60870-5-103, IEC 62056-21, RP570/71, DNP, Modbus, SEAB 1F, TG809 or SINAUT) as well as
pulse based (e.g. quantity pulse or relay contacts) transmission procedures. The specified bit
rate defines the maximum bit rate allowed, lower bit rates can still be transmitted.
3.2.3 Modulation
EDS500 series modems rely on FSK based modulation technology with adjustable
attenuation and equalizer to compensate line characteristics. 500FSD20 is able to report bad
line quality via an isolated alarm relay.
3.2.4 Multi-channel
500FSD10 and 500FSD11 are cost-efficient modems allowing to communicate on a 1200
bps V.23 or 9600 bps channel on one wire pair. The device 500FSD20 is in addition able to
operate in multi-channel environments allowing multiple separate data streams on the same
cable. Using this frequency multiplexing based technology it is possible to separate and run
multiple services on a single two- or four-wire cable. This can also be used to separate the
transmit and receive channels to allow full-duplex on two-wire installations.

System concept Functions overview
3.2.5 RTU560 integration
All products of the EDS500 series - FSK modems are also available as plugin modules for
RTU560.
3.3 Network structures
Devices of the EDS500 series allow you to realize a wide variation of network structures like
point-to-point connections, lines, stars and branches. The following small examples should
give an overview of possible network variants.
3.3.1 Line topology
A line topology usually follows the physical path of an infrastructure installation, e.g.
an energy line or pipeline. 500FSD analog modems realize a line topology by physically
connecting all modems to the same copper cable via two or four wires. In this so called
partyline or multidrop configuration the application protocol provides a polling scheme to
query and control the different stations.

Figure 1: Line topology
3.3.2 Point-to-point topology
Point-to-point connections can be used if possible by the physical environment or if high
throughput is required. The point-to-point connection can utilize either two or four wires.
In four wire mode the connection can be operated full-duplex allowing symmetric protocols
to be used (e.g. symmetric IEC 60870-5-101). If two wires are used, full-duplex operation can
be achieved by using 500FSD20 and frequency-separated channels in transmit and receive
direction.

different connections for the stations are bundled in the control center and are attached to a
single 500FSD analog modem. For star topologies two- or four-wire cabling is possible.
