• Transmission safety
• Minimum transmission times (real-time capable)
• Deterministic transmission
The DDLS 200 data transmission system, which is available in several model variations, makes possible the contact-free transmission of the following bus protocols:
•
•
•
•
•
•
•
•
PROFIBUS FMS, DP, MPI, FMS - DP mixed-operation, up to max. 1.5MBit/s, PROFISAFE

Operating principle
DDLS 200/XXX.1-YY
TNT 35/7-24V
To prevent the devices from mutually interfering with one another during data transmission in duplex
operation, they use two different frequency pairs. These are indicated by the type designation ….1
and ….2 as well as the label frequency f1 and frequency f2 on the control panel.
DDLS 200/XXX.2-YY
Optical data transmission on
two frequencies
f2
Figure 1.1:
f1
Operating principle
The receiving level is checked at both devices and can be read on a bar graph LED indicator. If the
receiving level drops below a certain value, e.g. due to increased soiling of the optics, a warning output
is activated.
All work on the device (mounting, connecting, aligning, indicator/operating elements) is performed
comfortably on the front side.

4.1
Mounting and alignment
An optical data transmission system, consisting of 2 DDLS 200 devices, involves mounting each of
the devices on mutually opposing, plane-parallel, flat and usually vertical walls with unobstructed view
of the opposing DDLS 200.
Make certain that, at the minimum operating distance Amin the optical axes of the devices are aligned
with one another within ± Amin • 0.01 to ensure that the transmission/reception beams of the two devices lie within the opening angle. This also applies for rotary transmission.
Note
The opening angle (angle of radiation) of the optics is ± 0.5° (wide angle: ± 1.0° or 1.5°) to
the optical axis! For all device models, the horizontal and vertical adjustment angles of the
fine alignment with the adjustment screws is ±6° for each. The optical transmission path between the DDLS 200s should not be interrupted. If interruptions cannot be avoided, be sure
to read the notice in chapter 11.4.
Therefore, pay close attention when selecting a suitable mounting location!

Attention!
When laying out a mobile arrangement for a DDLS 200, pay particular attention that the
alignment of the devices relative to one another remains unchanged over the transmission
path.
The transmission can be interrupted by e.g. jolts, vibrations or inclination of the mobile device due to irregularities in the floor or path.
Ensure adequate track stability! (see also "Diagnostic mode" on page 63)

Electrical connection
Attention!
Connection of the device and maintenance work while under voltage must only be carried
out by a qualified electrician.
If faults cannot be corrected, the device should be removed from operation and protected
against possible use.
Before connecting the device, be sure that the supply voltage agrees with the value printed
on the nameplate.
The DDLS 200… is designed in accordance with safety class III for supply by PELV (Protective Extra Low Voltage, with reliable disconnection).
For UL applications: only for use in class 2 circuits according to NEC.
Be sure that the functional earth is connected correctly. Error-free operation is only guaranteed if the device is connected to functional earth.
Described in the following two sub-chapters is the electrical connection of the supply voltage, the input
and the output.
The connection of the respective bus system is described in the following chapters.
4.4.1 Electrical connection - devices with screwed cable glands and terminals
To establish the electrical connections, you must first remove the red housing top with the optics. To
do this, loosen the three housing hex screws. The housing top is now only electrically connected to
the base by means of a connector. Carefully pull the housing top straight forward without skewing.

Device configuration PROFIBUS
Termination for devices with screwed cable glands and terminals
The PROFIBUS can be terminated via the switch S2 in the DDLS 200. If the termination is active
(S2 = On), internal bus resistors are connected as per the PROFIBUS standard and the PROFIBUS
is not wired through at terminals A’ and B’.
Activate the termination when the PROFIBUS segment begins or ends at the DDLS 200. The default
setting is termination inactive (S2 = Off).
Adjustment of the transmission rate
You must set the transmission rate of your PROFIBUS segment using the three DIP switches S3-1
through S3-3. Possible transmission rates are:
• 9.6 kBit/s
• 93.75 kBit/s
• 500 kBit/s 1)
• 19.2 kBit/s
• 187.5 kBit/s 1)
• 1500 kBit/s 1)
Set the transmission rate in accordance with the table printed on the connection circuit board (see
figure 5.1). The default setting is:
•
•

Changeover PROFIBUS / RS 485 (default: ’Off’ = PROFIBUS)
The DDLS 200 has, as a standard function, a repeater function (signal processing) and is, with regard
to the PROFIBUS, to be viewed as a repeater.
Note!
Please observe the guidelines specified in EN 50170 (Vol. 2) regarding the use of repeaters.
The delay time of a data transmission path is maximum 1.5 µs + 1TBit.
It is also possible to transmit other RS 485 protocols. For PROFIBUS applications, S3-4
should be set to 'Off' ('0'). DIP-switch S3-4 can be used to switch off the repeater function
for non-PROFIBUS applications (S3-4 = 'On'). In this case, no signal regeneration takes
place; the RS 485 protocol must, however, still provide certain features
Please contact the manufacturer if you would like to use the DDLS 200 for general
RS 485 protocols.

The DDLS 200 is an INTERBUS subscriber (Ident-Code: 0x0C = 12dec). A current CMD subscriber description can be downloaded from http://www.leuze.de.
If the value falls below the warning level (bar graph), a peripheral error message is transmitted via the INTERBUS. When this error message is transmitted, the usual cause is soiling
of the glass optics (see chapter 12.1 "Cleaning"), an incorrectly adjusted data transmission
path, or an interrupted light path.

9.2.1 Baud rate conversion
Through the use of an optical transmission system, the bus is divided into two segments. Different
baud rates can be used in the physically separated segments. The DDLS 200s then function as baud
rate converters. During baud rate conversion, it must be ensured that the bandwidth of the segment
with the lower baud rate is adequate for processing the incoming data.
9.2.2 Sorting (switch S4.1)
With the aid of switch S4.1, sorting of the internal memory can be activated and deactivated. If sorting
is deactivated (switch S4.1 = OFF, default), CAN frames are handled according to the FIFO principle
(First-In-First-Out).
If sorting is active (switch S4.1 = ON), CAN frames are sorted according to their priority. The message
with the highest priority in memory is the next one to be put onto the connected network for arbitration.

"Monitoring" of subscribers
If an DDLS 200 optical data transmission system is used in a DeviceNet or CANopen system, it is beneficial to monitor all subscribers to determine whether they are still participating in data exchange. The
following mechanisms are available for this purpose:
Heartbeat
Subscribers transmit cyclical heartbeat messages. If a message is not received for a certain period of
time, this is detected by the connected subscribers as a "Heartbeat Error".
Node / Life Guarding (CANopen)
The NMT Master (Network Management Master) cyclically queries all subscribers and expects an answer within a certain period of time. If this response is not received, a "Guarding Error" is detected.
Leuze electronic
Technical description DDLS 200

TNT 35/7-24V
If only data fragments are received as the result of the interruption in the optical transmission path,
these are detected and are not transmitted to the CAN bus segment. The connected subscribers are
not informed of an interruption in the optical transmission path via the protocol (switching output is activated). Data transmitted during the interruption are lost. The primary protocol is responsible for management of the subscribers. For this reason, the monitoring mechanisms of the primary protocol
should be used (Node/Life Guarding, Heartbeat, ...).
Leuze electronic
DeviceNet / CANopen
Response in the event of buffer overload
If, as the result of errors on the CAN bus segment, no DDLS 200 data can be transmitted to this segment or data can be transmitted only sporadically, the DDLS 200 reacts as follows:
1.
2.
3.
4.
CAN frames are temporarily stored
(64 frames for baud rates * 800kBit and 128 frames for baud rates < 800kBit).
If between 30% and 70% of the memory is occupied, the "BUF" LED flashes
If > 70% of the memory is occupied, the "BUF" LED is constantly illuminated
In the event of a buffer overflow, the memory is completely deleted.
Response in the event of errors on a sub-segment
Other segments are not informed of errors on a sub-segment.

Important notices for system integrators
Attention!
The notices provide initial information and describe the working principles of the optical data
transceiver with DeviceNet and CANopen.
The notices must be read by each user before the first commissioning of the DDLS 200 with
DeviceNet and CANopen.
Possible restrictions in the timing of the optical data transmission in comparison to copperbased data transmission are described here.
Due to the bit-synchronous arbitration mechanism in the CAN and the resulting high time requirements, arbitration via the optical, free-space data transmission system (abbreviated DT) is not possible. One original segment is divided into two sub-segments. Because of the division into multiple
segments, there are several points which must be observed when designing the system.

directly from there.
• The transmitted data are received by the DT2 and written in reception buffer OP (64 frames >
800kBit and 128 frames < 800kBit).
• Data in reception buffer OP are sorted by priority or processed according to the FIFO principle
(depending on the operating mode used)
• Data in reception buffer OP are passed to Segment 2 for arbitration.
• The same process also occurs when transmitting data from Segment 2 to Segment 1.

If a slave is addressed by a subscriber along an entire segment and expects an answer, twice the
propagation time must be planned for (twice the optical path).
If multiple optical paths are used in a system, the delay times may be added (depending on the constellation in the bus).
The increased delay times must be taken into consideration when parameterising the system.

Device configuration Ethernet
10.3.1 Autonegotiation (Nway)
If the switch S2.1 of the DDLS 200 is set to ON (default), the device is in autonegotiation mode. This
means that the DDLS 200 detects the transmission characteristics of the connected partner unit automatically (10Mbit or 100Mbit, full or half duplex) and adjusts itself accordingly.
If both devices are in autonegotiation mode, they adjust to the highest common denominator.
If a certain transmission type is to be required, the autonegotiation function must be deactivated (S2.1
= OFF). The transmission characteristics can then be set using the switches S2.2 and S2.3.
10.3.2 Transmission rate conversion
Through the use of an optical transmission system, the Ethernet is divided into two segments. Different transmission rates can be used in the physically separated segments. The DDLS 200s then functions as transmission rate converter. During transmission rate conversion, it must be ensured that the
bandwidth of the segment with the lower transmission rate is adequate for processing the incoming
data.

Important notices for system integrators
Attention!
The notices provide initial information and describe the working principles of the optical data
transceiver with Ethernet.
The notices must be read by each user before the first commissioning of the DDLS 200 with
Ethernet.
Possible restrictions in the timing of the optical data transmission in comparison to copperbased data transmission are described here.
Using the DDLS 200 for Ethernet, 10Base-T or 100Base-TX with 2Mbit is transmitted optically e.g. to
a moving rack serving unit where it is then converted back into 10Base-T or 100Base-TX.
The DDSL200 is connected to the Ethernet via a twisted pair port with an RJ45 connector or an M12
connector. An external switch reduces the data flow along the optical transmission path by filtering the
messages. Only messages for nodes located downstream of the optical data transmission path are
actually transmitted. The data throughput rate of the optical transmission path is max. 2Mbit/s.

Figure 10.10: Typical Ethernet bus configuration
The optical data path has a maximum data rate of 2MBit/s in each direction of data transmission. In
the network, it must be ensured that the average data rate in each direction of transmission is less
than or equal to 2MBit/s. This is, amongst others, achieved by the following measures.
• Address filtering by a preceding switch:
The preceding switch ensures that only messages are transmitted that are intended for the participant on the other end of the optical data transmission path. This leads to a significant reduction in
data
• Receiver buffer:
Via the 16kByte receiver buffer, brief peak loads can be managed without data loss. If the receiver
buffer overflows, the subsequent messages are rejected (dropped).
• Primary transmission protocol:
The primary protocol (e.g., TCP/IP) ensures that messages are re-sent if they are lost or have
remained unacknowledged. In addition, protocols such as TCP/IP automatically adapt to the available bandwidth of the transmission medium.

Changing the operating mode
AUT –> MAN Press the operating mode button for more than 2 seconds.
Only the device on which the button was pressed switches to the "Manual" operating
mode (MAN LED illuminates).
MAN –> ADJ Press the operating mode button on one of the two devices.
Both devices switch to the "Adjust" operating mode (both ADJ LEDs illuminate) when
both were previously in the "Manual" operating mode.
MAN –> AUT Press the operating mode button for more than 2 seconds.
Only the device on which the button was pressed switches to the "Automatic" operating mode (AUT LED illuminates).
Note!
If, while in the AUT operating mode, the operating mode button is pressed for longer than
13s, the device switches to a special diagnostic mode. The AUT, MAN and ADJ LEDs illuminate simultaneously (see chapter 13.2 "Diagnostic mode" on page 63).
To switch to the "Adjust" (ADJ) operating mode, both devices belonging to a transmission
path must first be in the "Manual" (MAN) operating mode. It is not possible to switch directly
from the "Automatic" to the "Adjust" operating mode or vice versa.

Commissioning / Operation (all device models)
11.3
Leuze electronic
Initial commissioning
11.3.1 Switch on device / function check
After applying the operating voltage, the DDLS 200 first performs a self-test. If the self-test is successfully completed, the PWR or UL LED illuminates continuously and the DDLS 200 switches to the "Automatic" operating mode. If the connection to the opposing device exists, data can be transmitted
immediately.
If the PWR or UL LED flashes after switching on, there are two possible causes: either a hardware
error has occurred or the transmitter/receiver unit has switched off via the switching input IN("Switching input" on page 18).
If the PWR or UL LED remains dark after switching on, there is either no voltage supply present (check
connections and voltage) or a hardware error has occurred.
11.3.2 Fine adjustment
If you have mounted and switched on the two DDLS 200s of a given optical transmission path and
they are both in the "Automatic" operating mode, you can perform the fine adjustment of the devices
relative to one another with the aid of the three alignment screws.
Note!
Note that with "alignment", the transmitter with the beam which is to be positioned as exactly
as possible on the opposing receiver is always meant.
At the maximum sensing distance, the bar graph does not show end-scale deflection even
with optimal alignment!
The DDLS 200 supports fast and easy fine adjustment. The optimisation of the alignment between
the two devices of one transmission path can be performed by just one person. Use the following
descriptive steps as a set of numbered instructions:
1.
2.
3.
4.
5.
6.
7.
60
Both devices are located close to one another (> 1m). Ideally, the bar graphs of both devices
display maximum end-scale deflection.
Switch both devices to "Manual" (MAN) by pressing the button for a relatively long time (> 2s).
Data transmission remains active, only the internal cut-off threshold is changed to the warning
threshold (yellow LEDs).
While in the "Manual" operating mode, move until data transmission of the DDLS 200 is interrupted. You can normally give the vehicle a run command up to the end of the lane. The vehicle
stops immediately upon interruption of data transmission. The devices are not yet optimally
aligned with one another.
Briefly press the button to switch both devices to the "Adjust" operating mode (ADJ). Data
transmission remains interrupted.
The devices can now be individually aligned. The result of the alignment can be read directly in
the bar graph.
When both devices are aligned, briefly pressing the button on one of the devices is enough to
switch both back to the "Manual" operating mode (MAN). Data transmission is again active; the
vehicle can continue its path. If data transmission is interrupted again, repeat steps 3 through 6.
If the data transmission and the alignment are OK through the end of the path of motion, switch
both devices back to the "Automatic" (AUT) operating mode by pressing the button for a relatively long time (> 2s). The optical data transceiver is now ready for operation.

Commissioning / Operation (all device models)
Operation
In running operation ("Automatic" operating mode) the DDLS 200 operates maintenance-free. Only
the glass optics need to be cleaned occasionally in the event of soiling. This can be checked by analysing the switching output OUT WARN (with the INTERBUS fibre optic cable model, a peripheral error message is also available). If the output is set, soiling of the DDLS 200's glass optics is often the
cause (see chapter 12.1 "Cleaning").
It must still be ensured that the light beam is not interrupted at any time.
Attention!
If, during operation of the DDLS 200, the light beam is interrupted or one of the two devices
is switched voltage free, the effect of the interruption on the entire network is equivalent to
the interruption of a data line!
TNT 35/7-24V
In the event of an interruption (light beam interruption or switched voltage-free), the
DDLS 200 switches off the network to a non-interacting state. The system reactions in the
event of an interruption are to be defined together with the supplier of the PLC.

Cleaning
The optical window of the DDLS 200 is to be cleaned monthly or as needed (warning output). To
clean, use a soft cloth and a cleaning agent (standard glass cleaner).
Attention!
Do not use solvents and cleaning agents containing acetone. Use of improper cleaning
agents can damage the optical window.

Note!
The INTERBUS 2MBit/s fibre optic cable model of the DDLS 200 is an INTERBUS subscriber (Ident-Code: 0x0C = 12dec). You can also use the diagnostic options available via the
INTERBUS.
13.2
Diagnostic mode
To enter the diagnostic mode, the DDLS 200 must be in the AUT state and the operating mode button
must be pressed for longer than 13s. After the button is released, all 3 operating mode LEDs illuminate. If the light beam is interrupted now, the 3 operating mode LEDs start to flash. This state is maintained until the flashing is acknowledged by a brief press of the button. Afterwards, the 3 operating
mode LEDs light-up permanently again. To exit the diagnostic mode, the button must pressed for more
than 13s.
Function-wise, the DDLS 200 acts during the diagnosis as if it were in AUT state. Hence, just a normal
data transmission takes place, and the thresholds for warning and switch-off are also the same as in
AUT mode.
Each DDLS 200 must individually be set to diagnostic mode. This is in contrast to switching from MAN
to ADJ mode, where both DDLS 200 change to ADJ state if one side has its button pressed.

In the diagnostic mode, the optical received signal level of the DDLS 200 is monitored. This function
is designed to support the diagnosis of short optical light beam interruptions as part of the bus diagnosis.
