Safety

Before installation:

Read this manual completely and gather all information on the unit. Make sure

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

Do not look directly into fibre optical fibre port or any connected fibre although

this unit is designed to meet the Class 1 Laser regulations.

Care recommendations

Follow the care recommendations below to maintain full operation of unit and to fulfil

the warranty obligations.

This unit must not be operating with removed covers or lids.

Do not attempt to disassemble the unit. There are no user serviceable parts inside.

Do not drop, knock or shake the unit, rough handling above the specification may cause

damage to internal circuit boards.

Do not use harsh chemicals, cleaning solvents or strong detergents to clean the unit.

Do not paint the unit. Paint can clog the unit and prevent proper operation.

Do not expose the unit to any kind of liquids (rain, beverages, etc). The unit is not

waterproof. Keep the unit within the specified humidity levels.

Do not use or store the unit in dusty, dirty areas, connectors as well as other mechanical

part may be damaged.

If the unit is not working properly, contact the place of purchase, nearest Westermo

distributor office or Westermo Tech support.

Fibre connectors are supplied with plugs to avoid contamination inside the optical port.

As long as no optical fibre is mounted on the connector, e.g. for storage, service or

transportation, should the plug be applied.

Product disposal

This symbol means that the product shall not be treated as

unsorted municipal waste when disposing of it. It needs to

be handed over to an applicable collection point for recy-

cling electrical and electronic equipment.

By ensuring this product is disposed of correctly, you will

help to reduce hazardous substances and prevent potential

negative consequences to both environment and human

health, which could be caused by inappropriate disposal.

Note. Fibre Optic Handling

Fibre optic equipment needs special treatment. It is very sensitive to dust and dirt. If the

fibre will be disconnected from the modem the protective hood on the transmitter/

receiver must be connected. The protective hood must be kept on during transportation.

The fibre optic cable must also be handle the same way.

If this recommendation not will be followed It can jeopardise the warranty.

Cleaning of the optical connectors

In the event of contamination, the optical connectors should be cleaned by the use of

forced nitrogen and some kind of cleaning stick.

Recommended cleaning fluids:

• Methyl-, ethyl-, isopropyl- or isobutyl-alcohol

• Hexane

• Naphtha

Maintenance

No maintenance is required, as long as the unit is used as intended within the specified

conditions.

Converter PROFIBUS DP – optical fibre

ODW-610-F2 is a fibre optic modem that converts between electrical PROFIBUS DP and

a fibre optical link.

Repeater – optical fibre links

ODW-610-F2 is a fibre optic repeater that repeats received data from one fibre link out

to the other link. This is useful e.g. for long distance communication, where electromag-

netic interference may occur or when isolation of the electrical network is needed. The

maximum optical fibre distance depends on selected fibre transceiver and fibre type.

Data rate up to 12 Mbit/s

ODW-610-F2 converts PROFIBUS DP data using data rates from 9 600 bit/s up to

12 Mbit/s. Retiming of the PROFIBUS DP data ensures that the correct signal form is

transmitted from the ODW-610-F2 converter.

Automatic data rate detection

The PROFIBUS data rate is set automatically as soon as the ODW-610-F2 receives a

correct data frame, whether data is received from PROFIBUS DP or the fibre optic link.

The detected data rate remains until a number of consecutive faulty received frames have

been detected or no further frames are detected within the timeout period. The time-

out period is set by switches, with the default setting of one faulty frame or 65 535 tbit

without any received frame.

6651-22611

Redundant ring via fibre optical network

Under normal operation the PROFIBUS DP data is sent over ring A.

Should a fault be detected on the fibre ring then the PROFIBUS DP data

will be carried on rings A and B.

… Normal operation, data exchange between PROFIBUS DP master and slave.

• UnitM receives PROFIBUS DP data (from a Master) at the electrical port, it converts

and transfers this master frame via the fibre ring A.

At unitM, the repeating of transferred frames is stopped until this transferred master

frame has returned to unitM via ring A.

• This master frame will be repeated through fibre ring A by all the other units. Each

of these units will also convert the master frame to PROFIBUS DP data and send it

via the electrical port.

• UnitS, to which the addressed Slave is connected, receives PROFIBUS DP data from

the Slave. UnitS converts slave data and transfers the slave frame via ring A.

The repeating of transferred frames is stopped until this transferred slave frame

has returned via ring A.

• When unitM receives the master frame (the same frame that has been transmitted

by this unit), or after a timeout, data conversion at unitM will be allowed again.

The received slave frame will be converted and transmitted at the electrical port.

• When unitS receives the slave frame (the same frame that has been transmitted by

this unit), or after a timeout, data conversion at unitS will be allowed again.

… Behaviour under faulty conditions

• Elapsed time from any kind of failure at the fibre optic network until data exchange

after a corrective action depends on total length of fibre ring.

This is typically 40–500 ms. During that time, the transferred data frames should be

seen as corrupted or missed.

… Recovery from faulty status

• ODW-610-F2 will automatically recover to the previous operating status when a

failure disappears. This involves recovery from multidrop application to Redundant

ring A/B when ring is up and running and recovery from Ring B to Redundant ring A

when the ring is up and running.

• The time to recover from the failure status depends on total length of fibre ring.

This is typically 40–500 ms. During that time the transferred data frames should be

seen as corrupted or missed.

Multidrop via fibre optical network

The electrical PROFIBUS DP network is transferred via the fibre optic network to the

electrical ports of all units. If ODW-610-F2 is connected to two optical fibre links (mid

unit) converted data will be transmitted in both directions, via both CH 1 and CH 2.

With only one optical fibre link (end unit) converted data will be transmitted in one

direction, via CH 1 only. Data received from one ODW-610-F2 optical fibre port will

be repeated through the other optical fibre port and it will also convert the frame to

PROFIBUS DP data and send it via the electrical port.
