Function
The LS611-DA-P is a device for serial data transfer in PROFIBUS systems with transfer rates up to 1500 kbit/s and ranges up
to 300 m. But the device can also be used without problem for data rates and operating ranges below these values. Two identical
LS611-DA-P devices are required to create the data transfer path.
Data transfer
The data are transfered in both directions by means of modulated infrared light. In this process the information at the input interface is modulated on the carrier signal in real time by means of Frequency Shift Keying (FSK). The appropriate demodulation
and output on the output interface takes place in the receiver.
Function displays/Stability control
A high-visibility alignment LED on the front of the device is provided to aid alignment. As soon as a receiver detects the light
emitted from the opposite device the flashing frequency of the alignment LED reduces. By going out, the same LED finally signals that the devices are optimally aligned with each other and that there is adequate stability control. For fine adjustment, the
optical data coupler is additionally provided with a bar graph display (Signal display), which provides a means of optimum adjustment.

Operation
The baudrate can be selected and modified by means of a push button. Operational readiness, data activity and fault signals
are indicated via LEDs. The push button can be inhibited to prevent manipulation and unintentional parameter changes via an
electrical signal.
Message processing.
In order to prevent the operation
of the connected bus from malfunction in the event of the interruption of the light beam, the
transfer of invalid messages is prevented. The signals are regenerated with bit and sign accuracy and sent to the bus with quartz
stability. This also provides the additional effect of optimum signal processing; the signal quality is electrically and timewise identical to that of the original PROFIBUS station.
Collision suppression
In systems with a number of light paths, in which there are active PROFIBUS stations ("Masters", e.g. operation panels) on the
moving side, a sequential fault can occur after a light path from a master has been broken, which leads to a collision with the
more important master of the master terminal station (Control), resulting in the considerable disruption of the data exchange on
the stationary side or even disruption of the data traffic with other light paths.

Optical data coupler
In order to avoid such a collision the function C1CP (Class 1 Master Collision Protection) can be brought into the circuit on the
stationary side. This prioritises the direction of transfer on this side after a light beam has become broken.
Mounting
Mounting takes place using an appropriate accessory, e.g. OMH-LS610-01 for wall mounting.
The x-y positioning is set prior to delivery. The device is secured in the desired beam direction (±90° rotation is possible) on the
support bracket.
