Functional description LD-63 Profibus

LD-63 Profibus is a line splitter for use in multi-drop fibre optic networks. The LD-63 Profibus allows conversion between RS-485 and fibre optic. The unit is specially developed for Profibus and uses a Profibus standard 9-position D-sub for connection with RS-485. Possibility to connect to a 5-position screw block is also available.

The fibre optic interface uses ST-connectors and both multi mode and single mode fibre versions are available. The maximum transmission distance is calculated from the available power budget of the modems and the attenuation of the cable, splice joints and connectors. Distances up to 25 km can be reached using single mode fibres.

The modem consists of two F/O channels, each with its separate transmitter and receiver (TX1, TX2, RX1 and RX2). On the front of the unit there are seven LED’s indicating the datatransmission on the channels.

LD-63 Profibus can be used at all standard Profibus transmission speeds up to 1.5 Mbit/s and all operating parameters are set-up via DIP switches easily assessable under the lid on the top of each unit.

LD-63 Profibus is available in low (LV) and highvoltage (HV) versions. LD-63LV supports power supplies 12–45V AC ± 5% and 12–55V DC ± 5%. LD-64HV supports power suppplies 95–240V AC ± 5% and 110–240V DC ± 5%.

Retiming inactivated

Retiming implies that the incoming data on fibre side will be retimed to an exact bitlength depending on configured transmission speed. This gives the possibility to connect an increased number of units in serie. Retiming is only possible at adjustable speeds and not at ”auto detect mode”.

Number of units is depending on the data rate and the total system. Retiming (see S1:2) increases the number of possible units but also introduces a delay in the system. ”Number of units” means a typical value that can be changed depending on the structure of the total system.

Termination

The fail-safe function forces the received signal to inactive state when the connected transmitter is in tri-state (transmitter inactive).

Normally high power is used. Low power is used with fiber lengths shorter than 100 m.
