Converter serial interface – optical fibre

ODW-630-F2 is a fibre optic modem that converts between electrical RS-485 and a fibre optical link.

ODW-630-F2 can also be used to convert from RS-232 to RS-485 by using a ODW-620-F2 and ODW-630-F2.

Repeater – optical fibre links

ODW-630-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 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.

Data rate up to 1.5 Mbit/s

ODW-630-F2 converts data using rates from 300 bit/s up to 1.5 Mbit/s. Retiming of the data ensures that the correct signal form is transmitted from the ODW-630-F2 converter.

road and railway applications

ODW-630-F2 complies with standards for industrial environments and railway signalling and telecommunications apparatus. Additionally, the wide climatic range of the ODW-630-F2 allows it to be installed in out-door cabinets without any additional measures, such as heating, etc.

Redundant ring via fibre optical network

Under normal operation the serial data is sent over ring A. Should a fault be detected on the fibre ring then the data will be carried on rings A and B.

Ring A

Ring A Ring A Ring A

Ring B Ring B Ring B

Ring B

Note! Ring A start up at TX (channel 1) and ring B ends up at RX (channel 1).

… Normal operation, data exchange between serial master and slave.

• ODW-630-F2 unit connected to the PLC-master receives serial data at the electrical port, it converts and transfers this master frame via the fibre ring A. At this unit the repeating of transferred frames is stopped until this transferred master frame has returned 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 serial data and send it via the electrical port.

• ODW-630-F2 unit to which the addressed Slave is connected, receives serial data from the Slave. This unit 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 the “first” ODW-630-F2 unit receives the master frame (the same frame that has been transmitted by this unit), or after a timeout, data conversion at will be allowed again. The received slave frame will be converted and transmitted at the electrical port.

Page 9

6651-22651

• When the ODW-630-F2 unit connected to the PLC slave receives the slave frame (the same frame that has been transmitted by this unit), or after a timeout, data conversion at this unit 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 (local unit). During that time, the transferred data frames should be seen as corrupted or missed.

Note: Be ware of that full duplex will not work in redundant ring.

Failure Indications

Fibre interruption ring A, TX On: FL R Fibre interruption ring A, RX On: FL L Fibre interruption ring A, RX & TX On FL L Fibre interruption ring B, TX On: FL R Fibre interruption ring B, RX On: FL L Fibre interruption ring B, RX & TX On: FL L Fibre interruption ring A and B (e.g. CH1 or CH2 both TX & RX) On: FL L &/or FL R Low power on the receiver (May indicate bad fibre)

* Regarding functionality see chapter “multidrop application”

FLL flicker

… Recovery from faulty status

• ODW-630-F2 will automatically recover to the previous operating status when a

failure disappears. This involves recovery from multi drop 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.

Serial data transfer can be set in two modes: Synchronous mode: Transfer special protocols such as Manchester coded protocol.

See special switch settings on page 20. Asynchronous mode: 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.

The data is transferred via the fibre optic network to the serial ports of all units. If ODW-630-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-630-F2 optical fibre port will be repeated through the other optical fibre port and it will also convert the frame to serial data.

6651-22651

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 links. The alarm will be set until the fibre optical links are in operation and ready to transfer serial data.

Data frames are transferred over the fibre optic links as long as the links are in operation and the data rate has been detected.

When any of the fibre optic links is out of operation, this will be indicated by a local alarm, and this will set the alarm output. It will also send a remote alarm via the other link, if possible. When the link returns to operations mode, the alarm will reset automatically.

RS-485 interface

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. Manchester coded protocol can be transferred with Synchronous mode.

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

ODW-630-F2 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, allowing redundancy should either supply fail.

Single- or multimode LC fibre connectors

ODW-630-F2 use Small Form Factor Pluggable (SFP) transceivers that are in compliance with the Multi-Sourcing Agreement (MSA). This means that 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.

6651-22651

System delay in an optical network

Data exchange between a serial master and slave via ODW-630-F2 fibre optic link, will be delayed due to the length of the optical fibre and the signal processing within the ODW-630-F2. The signal processing delay is dependent on the data rate, and the fibre delay is dependent on the total length of the optical fibre.

There is no limitation of the total length of optical fibre for Multi-drop applications. In Redundant ring applications the data transfer time in a ring is limited to 10 milliseconds. This means the total length of the optical fibre ring is about 2 000 km, excluding the 1 microsecond delay at each optical repeater unit.

The additional time resulting from the optical fibre and ODW-630-F2 is the Overall system delay. The Redundant ring and Multidrop application Overall system delays differ, see below.

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).

Example:

The data speed in a particular application is 250 kbit/s.

Calculate the maximum data transition time: 1/250 x 10

= 4 x 10

Using dip-switches 1:3 – 1:6, set the transmitter on time to the closest higher value, e.i. 4.3 µs.

= 4 µs.

Note: With Bi-di fibre it is necessary to have one 1310 nm in one end

and 1550 nm in the other end.

• Bi-di 1310 nm will transmit with 1310 nm and resceive with 1550 nm.

• Bi-di 1550 nm will transmitt with 1550 nm and resceive with 1310 nm.

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 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.

The definition of positive and negative T/R+, T/R– and R+, R– can differ between this ODW-631 and other units so it can be helpful to reverse the connection of + and –.
