Product Description
4 Product Description
4.1 LS680-DA - Use and application
The optical data coupler serves as an optical link between two Ethernet devices;
typically one is mobile. The opening angle is optimized for operations in high rack
storage.
With the optical data coupler, devices with industrial Ethernet topologies, such as
PROFINET, Ethernet/IP and other Ethernet protocols, can be connected. The
physical transfer takes place protocol-free with 100 MBit/s full duplex. The
connection to a number of modules must be implemented using switches that
have been certified for use with the bus system in question. All layer 2 telegrams
(IEEE 802.3 Clause 25) are physically transported. There is no saving of
telegrams, so the transfer is not delayed at all.
Modules operating at a data rate of 10 MBit/s can be connected using a switch.
Isochronous real-time systems can also be driven to a certain extent on account
of the variable light propagation time.
The LS680 uses semiconductor lasers as optical transmitters. The dilation of the
light beam and the use of return map blocks guarantee the harmlessness of the
devices in accordance with laser class 1M. The transmitting beam must not be
viewed with telescopes or binoculars from distances of less than 20 m. At longer
distances, the limit values for laser class 1 are not exceeded, even when viewed
through a telescope with a 50 mm aperture.

PWR
Lights up when the device is connected to the supply voltage.
ERR
Status of the overall connection. Lights up if the signal is not strong enough to establish a connection (if misaligned or if the light beam is obstructed) and also when there is a fault on the optical
channel, e.g., as a result of extraneous light. It must not illuminate under normal circumstances.
LAN
Status of the cable connection. The LAN LED (yellow) indicates a physical connection to the next
module on the cable. If it is not on, this indicates a connection problem. The LAN LED lights up permanently as long as no data is being transferred. Flashing of the LAN LED indicates the presence
of data packets on the LAN.
OPT
Status of the optical connection. The OPT LED flashes when the optical connection is stabilized
through correct alignment.
SIGNAL
Indicate the reception signal strength. Reaching the yellow area is sufficient to indicate error-free
reception. If the alignment is correct, two green LEDs should light up at the nominal det ection range.
To avoid excessive bus loading due to transmission errors, data transfer is blocked below the yellow area.
LASER ERROR
If the permitted internal temperature is exceeded, this LED will flash, although the transmission
power is not reduced. If an internal activation error such as overcurrent is detected, the laser is
switched off, and an attempt then made every second to resume normal operation. Meanwhile, the
LASER ERROR LED lights up for 30 secs ... 60 secs, even if the process was unique, e.g., as the
result of an EMC event.

Installation
Mounting on a P+F adjustment device
The mounting accessories (OMH-LS610-01) consist of a mounting bracket and
an integral alignment device (in x and y axes). The required beam direction (± 90°
rotation) can be set using the mounting accessories, which are fastened to the
mounting bracket using two M4 screws and the central M6 screw. The central
screw is for securing the unit in place following adjustment and should not be
tightened until the adjustment is finalized. To mount the optical data coupler,
squeeze the two front levers together and place feet into the four openings in the
adjustment device. The feet have to lock into place so that the levers can be
released outwards as far as the stop; if necessary the optical data coupler has to
be pressed down applying some force from the top to the center.
5.3 Connection
Connecting the power supply
The device conforms to protection class III. This means that the power has to be
supplied as a low protective voltage (PELV) and limited according to UL Class 2
(100 W). The power supply of the optical data coupler is a 18 V to 30 V DC. The
dielectric test voltage (shield against power/GND) is 50 V maximum.
To supply power to the sensor, proceed as follows:
1. Plug the 4-pin M12 mating cordset into the connector on the rear of the housing.
2. Screw the cap nut as far as it will go over the connector. This ensures that the
power cable cannot be inadvertently pulled out.
3. Now connect the supply voltage to the cable provided.
The sensor is now ready for operation.

Installation
Grounding / Shielding
This type of grounding is not protective grounding, it acts solely as a down
conductor for cable-related faults and is not subject to any safety guidelines (e.g.
personnel protection). Functional grounding of the shields is required to provide
immunity to interference.
To ground the device, proceed as follows:
1. Make up a ground cable using a 6 mm flat connector with an adequate crosssection ( 1.5 mm²).
2. Plug the flat connector onto the pre-mounted insertion prong on the device.
3. Connect the other end of the ground cable to adjacent metal components
(e.g. mounting base, frame, etc.).
The device is now grounded.
Connecting the network
Both devices are connected to an M12 D-connector with the standard assignment
for PROFINET or Ethernet/IP. The LS680 automatically locates transmit and
receive lines (Auto-MDIX), so no crossover cable has to be used.
To connect the sensor to a network, proceed as follows:
1. Plug the 4-pin M12 mating cordset into the network connector on the rear of
the housing.
2. Screw the cap nut as far as it will go over the connector. This ensures that the
power cable cannot be inadvertently pulled out.
3. Now connect the network cable to the network connection provided for this
purpose.
The sensor is now ready for operation.
Note!
Data cables must conform CAT5. Do not use UTP (unshielded twisted pairs) for
reasons of electrical immunity.
5.4 Storage and transport
For storage and transport purposes, package the unit using shockproof
packaging material and protect it against moisture. The best method of protection
is to package the unit using the original packaging. Furthermore, ensure that the
ambient conditions are within allowable range.

6.1 Adjustment
Alignment aid/ signal strength
An alignment LED, which can be seen from a long way off, is located on the front
panel as an alignment aid. As soon as a receiver detects the transmitter light of
the device opposite it, the flashing frequency of the alignment aid decreases. If
the light goes out, this indicates that the devices are optimally aligned and
sufficient signal strength is available. The bargraph display shows the receiving
level. The optical data coupler is designed to ensure that an adequate level of
received light is obtained over the entire transmitter. For technical reasons,
however, the maximum received light is often not in the center of the spot. To
ensure the best possible alignment, center the light spot horizontally and vertically
with the other optical data coupler device. The drop-off in intensity at the edge of
the spot is very pronounced, which makes the edges easy to locate.

Figure 6.1 Explanation of display and operating state
In “high signal strength” mode (green zone), the received signal strength of the
optical data coupler is sufficient for operational purposes. The optical data coupler
should operate in the green zone within the nominal range (at least one green
LED); if the received strength drops below this limit level, the alarm output is deenergized. Telegrams continue to be sent until the received strength drops below
the level required for operational purposes (red LED only).

Commissioning
Aligning using the adjustment alignment aid
The beam axis is aligned in the x and y direction using the two adjustment screws
(hollow, 5 mm). This position is then fixed by tightening the central screw. Ethernet
data communication is not needed for the alignment.
Alignment sequence
1. Place the adjustment alignment aid on the bracket in the required direction and
tighten the two M4 nuts. Screw in the M6 central screw, but do not tighten it yet.
2. Place the optical data coupler in the adjustment alignment aid. Connect the
power supply (Power).
3. Roughly align the device at a distance of around 3 - 5 m until both signal
indicators lie in the green zone. Ensure that the optical data couplers are at
the same height and are not offset.
4. Move both optical data couplers about 20 m apart and turn the adjustment
screws Y until the alignment LED starts to flash slowly. Now turn the same
screw in the opposite direction, counting the number of turns that the
alignment LED remains off before it starts flashing again. Finally, turn the
adjustment screw back (towards the middle) by half the number of turns.
Perform the same procedure in the x direction.
5. Increase the distance to maximum. Adjust the device further if necessary.

Parallel light paths
If two transmission paths are installed next to each other without any optical
separation, then the optical data couplers must be installed opposite in pairs to
avoid cross-talk. A minimum distance ‘a’ between the beam axes is not required,

adjustment, as the height adjustment can mechanically modify the lateral
position, but not the other way round.
Once you have made the adjustments, tighten the central M6 screw to fix
the position in the horizontal direction.

In such arrangements, disconnecting one side of an optical data coupler is not
permitted. Similarly, the light beam must not be obstructed.

Parallel arrangement with VDM100 distance measurement sensors
The optical data coupler and distance measurement sensors of the type VDM100
can be arranged in parallel. A minimum distance of the units is not required.
6.2 Topology
The optical data coupler does not contain any address routing logic (switch). This
means that the distribution of the information must always be controlled by an
external switch. The internal Ethernet adapter is permanently set to 100 MBit full
duplex, as this is the only format that is converted for the optical transmission. Any
adjustments required to connection modes must be made using the external
switch. The pair of optical data couplers effectively replace a cable, the maximum
cable lengths always relate to the distance from the ODC to the appropriate
switch. The signal propagation time, on the other hand, depends on the physical
distance between the two ODCs; it amounts to 3.3 ns for each meter of light path.
