that you understand it fully. Check that your application does not exceed the safe
operating specifications for this unit.
This unit should only be installed by qualified personnel.
This unit should be built-in to an apparatus cabinet, or similar, where access is
restricted to service personnel only.
The power supply wiring must be sufficiently fused, and if necessary it must be
possible to disconnect manually from the power supply. Ensure compliance to
national installation regulations.
This unit uses convection cooling.To avoid obstructing the airflow around the unit,
follow the spacing recommendations (see Cooling section).
Before mounting, using or removing this unit:
Prevent access to hazardous voltage by disconnecting the unit from power supply.
Warning! Do not open connected unit. Hazardous voltage may occur within this
unit when connected to power supply.
Class 1 Laser Product

The ODW-611 is a fibre optic modem for point to point applications, that converts
between electrical PROFIBUS DP and fibre optical link.The maximum distance of
the fibre link depends on selected transceiver and fibre type. Distance up to 80 km
(50 miles). ODW-611 is designed for harsh out-door usage, in industrial, road or
railway installations.The PROFIBUS data rate is set automatically as soon as ODW-611
has identified a correct data frame. Retiming ensures the correct PROFIBUS DP signal
format.

Converter PROFIBUS DP – optical fibre
ODW-611 is a fibre optic modem that converts between electrical PROFIBUS DP and
fibre optical link.
Data rate up to 12 Mbit/s
ODW-611 converts PROFIBUS DP data in data rate from 9600 bit/s up to 12 Mbit/s.
Retiming of the PROFIBUS DP data ensures that the correct signal format is transmitted
from the ODW-611 converter.
Automatic data rate detection
The PROFIBUS data rate is set automatically as soon as ODW-611 has identified a cor-
rect data frame, independently of whether data is received from PROFIBUS DP or the
fibre optical link. Detected data rate remains until a number of consecutive faulty
received frames or after a delay without any received frame.This is set by switches, with
default setting of one faulty frame or 65 535 tBit.
Point to point communication via fibre optical network
The electrical PROFIBUS DP network is transferred via a fibre optical network by the
use of two ODW-611 units.This application is useful e.g. for long distance communica-
tion, where electromagnetic interferences may occur or when isolation of the electrical
network is needed.
The maximum optical fibre distance depends on selected fibre transceiver and fibre type.
Distance up to 80 km (50 miles).

Functionality and status indication
At power on, all LED's will be active during an initiation sequence followed by an auto-
matic initiation of the optical fibre link.The alarm will be set until the fibre optical link is
in operation and ready to transfer PROFIBUS DP data.
Data frames are transferred over the fibre optical link as long as the link is in operation
and the data rate has been detected.
When the fibre optical link is out of operation, it will be indicated by a local alarm, and
this will set the alarm output. When the link returns to operations mode, the alarm will
rest automatically.
The Bus active (BA) LED is set if data frames are received on the electrical PROFIBUS
DP port and the data rate is detected, independently of the status on fibre optical link.
Redundant power supply, galvanic isolated (2 kVAC) to other ports
ODW-611 should be supplied with safety extra low voltage (SELV). It is designed to
operate permanently over a wide input range and provided with two independent inputs
for enhanced redundancy if either supply fails.
9-position D-sub PROFIBUS DP connector
The pin assignment for the connector is in compliance with PROFIBUS standard
EN 50 170.
Single or multimode LC fibre connectors
ODW-611 uses Small Form Factor Pluggable (SFP) transceivers that are in compliance
with Multi-Sourcing Agreement (MSA). A wide range of different fibre transceivers and
connectors can be used.
Status port
This port enables supervision of fibre optical link status by a relay with both normally
open and closed contacts.
The status will be set if:
• Local or remote fibre link errors exist.
• The unit is out of service, e.g. no power supply.
Designed for hash environments, such as industrial, road and railway
applications
ODW-611 complies with standards for industrial environments and railway signalling
and telecommunications apparatus. Additionally the wide temperature range ODW-611
permits it to be installed in out-door cabinets without any additional measures, such as
heating, etc.

10 6650-2201
System delay in an optical network
PROFIBUS DP data transferred from one ODW-611 unit via an optical network to a
second unit will be delayed, due to the length of optical fibre and the signal processing
within the unit.The signal processing delay is dependent on the data rate, and the fibre
delay is dependent on the total length of the optical fibre.
Delay @ Up to 1.5 Mbit/s Delay @ 3 /12 Mbit/s
Optical fibre length delay (typical) 5 μs/km 5 μs/km
Signal processing, electrical to fibre (max) 1 tBit + 1.0 μs 5 tBit + 1.0 μs
Signal processing, fibre to electrical (max) 0.3 μs 0.3 μs
Overall system delay, one-way. From received 5 μs/km + 5 μs/km +
PROFIBUS DP data at one unit until 1.0 μs + 1 tBit 1.0 μs + 5 tBit
transmitted data at the other unit
Overall system delay, Delay @ 0.5 Mbit/s Delay @ 1.5 Mbit/s Delay @ 12 Mbit/s
one-way
200 m fibre length 4.0 μs 2.7 μs 2.4 μs
2000 m fibre length 13.0 μs 11.7 μs 11.4 μs
Note tBit = 1 / Baud rate (Baud rate in Bit/s)
Example
During configuration of the PROFIBUS DP master it may be necessary to adjust the
bus parameter Slot time, the monitoring time (tBit) of the sender of the frame for
acknowledgement of recipient.The additional time resulting from the optical fibre and
ODW-611 is twice the overall one-way delay.

Optical Power Budget
The maximum supported link lengths as specified in table above should only been seen as
indicative.The allowed link length is calculated from the Optical Power Budget (OPB), the
available optical power for a fibre-optic link, and the attenuation of the fibre, comprising
losses due to in-line connectors, splices, optical switches and a margin for link aging
(typical 1.5 dB for 1300 nm).
The worst-case Optical Power Budget (OPB) in dB for a fibre-optic link is determined
by the difference between the minimum transmitter output optical power and the lowest
receiver sensitivity.

Start up guide
Follow the steps below to get the unit up and running in a simple application.
… Use the factory DIP-switch settings.
… Connect The fibre link between the both units.
… Connect the power supply to both ODW-611.
• The Fibre link should be in operation, indicated by active CH1 LED.
… Connect the PROFIBUS DP connectors between both ODW-611 and PROFIBUS
units configured to be units in the PROFIBUS DP network.
• The PROFIBUS DP will be in operation and the data rate should have been
identified, indicated by BA LED.
… The point to point application is up and running.
Hints
… If the distance is long it may be necessary to adjust the bus parameter Slot time, the
monitoring time (tBit) of the sender of frame for acknowledgement of recipient, at
configuration of the PROFIBUS DP master.
… If the time between transferred PROFIBUS DP frames is long, it may be neccessary to
allow a longer time of interruption in receiving frames, using DIP-switches.
… If disturbances in the PROFIBUS DP network, result in missed frames, it may be
necessary to allow a number of consecutive faulty frames before the bus is out of
operation, using DIP-swithes.
