Optical data coupler
LS610-DA-P/F2/146
The LS610-DA-P is a device for serial data transmission in PROFIBUS-Systems at transmission rates up to 1500 kbit/s and a
distance range covering up to 240 m. Of cause the device can be employed at transmission rates and distance below these
values without any problems. A data transmission path consists of two devices LS 610-DA-P, one working at centre frequency
F1 and one working at centre frequency F2.
Data transmission
The data transmission is carried out by means of modulated infrared light in both directions. In the Emitter, the input interface
information is modulated onto the carrier signal by frequency shift keying (FSK) in real time. In the receiver the incoming optical
signal is de-modulated and made available at the output interface.
Function indicators/Function reserve
As adjustment aid, the device is equipped with a alignment LED, which can be observed over a long distance. As soon as a
receiver detects an incoming optical signal from the opposite device, the alignment LED’s flashing frequency slows down. Going
out indicates a good alignment and sufficient function reserve. For fine adjustment the device is equipped additional with a bar
graph-Indicator (signal-indicator), which makes an optimal alignment possible.

PROFIBUS
Connection between indicator and device status
If the bus is active, a yellow LED „RX“ (receive data) and a green LED „TX“ (transmit data) light up.
Operating
Due to two membrane keys, parameters like transfer rate and telegram verification can be selected and modified. The visualization of ready status, data transfer and error message is carried out via LEDs. to avoid manipulation or inadvertently parameter
change the keys can be electrically locked.
Telegram processing
To avoid bus error, caused by light beam interruption, Telegram Verification Technology (TVT) is implemented in this device.
The TVT prevents from transfers of invalid telegrams. The data get recovered bit by bit and word-fairly and are applied to the
bus quartz-stabilized. Thus an optimal signal conditioning is performed. The signals are electrically identical and simultaneous
to the original PROFIBUS clients signals.
The TVT can be de-activated. Due to this, the data transfer is mostly protocol free and the device is suitable for transferring
RS485 protocols, which have different timing conditions to the PROFIBUS.
Bus termination
If the data coupler is located at the end of a bus topology, a bus termination is required. An external standard termination resistor
(refer accessories) has to be connected to the M12 connector „Bus OUT/Termination“.
Installation
The mounting is carried out by using the suitable mounting accessory e. g. OMH-LS610-01 for wall mounting.
The x-y-adjustable carrier is delivered pre-assembled.It can be mounted in the desired direction (±90° rotation is possible) It
may be tightened not before mounting onto the mounting bracket by means of 2 M4-screws and the central M6-screw. The final
fixation after alignment is carried out by means of the central screw.
The data coupler can be snapped onto the alignment fixture, when the both spring forced handles at the front end of the fixture
are pressed together. After snap in, the handles must be released for a reliable fixation of the device.
By means of the two adjustment screws (female hexagon 5 mm) the beam axis can be aligned in X- and Y-direction. Finally the
alignment gets fixed by tightening the central screw.
