Converter serial interface – optical fibre

ODW-621/631 is a fibre optic modem that converts between electrical RS-232 or

RS-485 and a fibre optic link.

ODW-621/631 can also be used to convert from RS-232 to RS-485 by using one

ODW-621 and one ODW-631.

Repeater – optical fibre links

ODW-621/631 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 electromagnetic 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.

Distances up to 80 km (50 miles) are available.

Data rate up to RS-232 – 250 kbit/s, RS-485 – 1.5 Mbit/s

ODW-621/631 converts data using rates from 300 bit/s up to 250 kbit/s (RS-232) or from 300 bit/s up to 1.5 Mbit/s. (RS-485) Retiming of the data ensures that the correct signal form is transmitted from the ODW-621/631 converter.

6650-2221

Point to point communication via fibre optical network

The serial interface is transferred via a fibre optic network between two ODW-600s.

This application is useful e.g. for long distance communication, where electromagnetic interference may occur or when isolation of the electrical network is needed. The maximum optical fibre distance between two units depends on selected fibre transceiver and fibre type. Distance up to 80 km (50 miles) are available.

Serial interface fully transparent or protocol dependent

Serial data transfer can be set in two modes:

… Transparent: Data will be directly sent over the fibre optic network, without any start-bit control and without any turning time delay when using the RS-485 interface. This is only recommended when the date is an unidentified protocol or data rate. This mode is not recommended when using RTS/CTS control or RS-485 two-wire.

… Protocol dependent: Data will be sent over the fibre optic network when a startbit has been identified. The data rate and number of data bits should be set by

DIP-switches. The turning time (from sending serial RS-485 data until changing to receive mode) is automatically calculated from the DIP-switch setting.

This is the preferred mode.

6650-2221

RS-485 termination at system level

The system should be installed in according to the RS-485 specification. A system should always form a bus structure where the termination is at the end points of the bus.

See diagrams for details of how this is done with RS-485 2-wire and 4-wire.

Optical fibre link functionality and status indication

At power on, all LED’s will be active during an initiation sequence followed by an automatic initiation of the optical fibre link. The alarm will be set until the fibre optic link is in operation and ready to transfer serial data. Data can be transferred over the fibre optic link as long as the link is in operation.

When the fibre optic link is out of operation this will be indicated by a local alarm output. When the link returns to operation, the alarm will reset automatically.

RS-232 interface (ODW-621)

A 9-position female D-sub connector that handles full duplex data rates up to 250 kbit/s.

With transparent mode the RS-232 interface can handle an arbitrary data rate up to

250 kbit/s without any data rate or data bit settings. With protocol dependent mode, one of the data rates from 300 bit/s to 250 kbit/s and one of the word formats

(9 to 12 data bits) should be set.

With RTS/CTS control selected, the request to send (RTS) signals will be transferred between the ODW-621s over the fibre optic network. These RTS signals are transferred independently of the data transfer. An RTS signal received at one ODW-600 will set the clear to send (CTS) signal at the other converter.

The data carrier detect (DCD) signal is set as long as the fibre link is in operation, ready to transfer data. The data set ready (DSR) signal is set as long as the ODW-600 is in service.

RS-485 interface (ODW-631)

A 4 position detachable screw terminal that can handle full duplex data rates up to

1.5 Mbit/s and can be set to either 2- or 4-wire RS-485 system.

When 4-wire RS-485 is selected, the terminals T/R+ and T/R– will always be set to transmit and terminals R+ and R– will always receive data.

Redundant power supply, galvanic isolated (2 kVAC) to other ports

The ODW-600 should be supplied with safety extra low voltage (SELV). It is designed to operate permanently over a wide DC or AC voltage input range and provided with two independent inputs for enhanced redundancy if either supply fails.

Single- or multimode LC fibre connectors

The ODW-600 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 interface

This port enables supervision of fibre optic link status by a relay with both normally open and closed contacts.

The status will be set if:

• Local or remote of fibre link errors exist.

• The unit is out of service, e.g. no power supply.

6650-2221

Designed for hash environments, such as industrial, road and railway applications

The ODW-600 complies with standards for industrial environments, railway signalling and telecommunications apparatus. Additionally the wide temperature range permits it to be installed in out-door cabinets without any additional measures, such as heating, etc.

System delay in an optical network

Serial data transferred from one ODW-600 via an optical network to a second one, will be delayed due to the length of optical fibre and the signal processing within the units.

The signal processing delay is dependent on the data rate and conversions, and the fibre delay is dependent on the total length of the optical fibre.

*** The optical power should be reduced by at least 5 dB (SM-LC80) or 3dB (SM-LC80) between the optical output and input.

Optical Power Budget

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 ageing (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 transmitter’s output optical power (min) and the receiver input sensitivity (max).

… Configure the ODW-600s. Using the factory DIP-switch settings, set:

… S1: RS-232 or 2-wire RS-485, data control, 9 600 bit/s, 10 data bits

(e.g. 8 data bits, 1 start and 1 stop bit, no parity).

… S2: Protocol dependent mode, with start-bit control.

… S3: No termination and fail-safe of the RS-485 port.

… Connect The fibre link between the ODW-600s.

… Connect the power supply to both ODW-600s.

… After a few seconds the fibre link should be in operation, indicated by an active

CH1 LED.

… Connect the serial cables from PLC master and slave to respective ODW-600s.

… Frames from PLC master that are correctly received the ODW-600 should be indicated by flashing TD LED.

… Frames that are received via the fibre link will be transmitted to the PLC slave and indicated by flashing RD LED.

… Replies from slave to master will be transferred and indicated in the opposite way.

… The point to point application is up and running.

6650-2221

Hints

If the distance is too long, it may be necessary to adjust the timing of the sender of the frame to allow acknowledgement of of the received frame, during configuration of the

PLC master.

Ensure that the correct protocol dependent configuration has been selected.

Flashing of the TD LED indicates that a start-bit has been identified.

If protocol parameters, data rate and bits are unknown. Transparent mode may be used as an alternative, as long as 2-wire RS-485 is not used.

The definition of positive and negative T/R+, T/R– and R+, R– can differ between this

ODW-600 and other units so it can be helpful to reverse the connection of + and –.
