Features of the DDLS 200
The fact that bus systems are found in nearly all areas of industry places high demands on data trans-
mission systems. The DDLS 200 fulfills these requirements, particularly with regard to:
• Transmission safety
• Minimum transmission times (real-time capable)
• Deterministic transmission
The DDLS 200 data transmission system, which is available in several model variations, enables the
contactless transmission of the following bus protocols:
• PROFIBUS FMS, DP, MPI, FMS - DP mixed operation, up to max. 1.5MBit/s, PROFISAFE
• INTERBUS 500kBit/s, RS 422 general, copper conductor
• INTERBUS 2MBit/s / 500kBit/s, fiber-optic cable
• Data Highway + (DH+) from Rockwell Automation (Allen Bradley)
• Remote I/O (RIO) from Rockwell Automation (Allen Bradley)
• DeviceNet
• CANopen
• Ethernet for all protocols based on TCP/IP or UDP
Other bus systems on request.
1.4 Operating principle
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.
Figure 1.1:Operating principle
The received signal level is checked at both devices and can be read on a bar graph LED indicator. If
the received signal 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, indicators and operational controls) is per-
formed comfortably on the front of the device.

4 Mounting / Installation (all device models)
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 sure that, at the minimum operating distance Amin, the optical axis of the devices is mounted
within the opening angle (angle of radiation, ± Amin • 0.01). This also applies for rotary transmission.
Mount each device with four screws  5 mm using four of the five fastening holes in the mounting plate
of the device (see chapter 3.2 "Dimensioned drawings").
Figure 4.1: Mounting the devices
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 ° each. The optical transmission path
between the DDLS 200s should not be interrupted. If interruptions cannot be avoided, be
sure to observe the notices 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 transmission path, pay particular
attention that the alignment of the devices relative to one another remains unchanged.
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 64)

4.3 Cascading (series connection) of several DDLS 200 data paths
If there are multiple optical data transmission paths between two communicating participants (TN),
one speaks of cascading. There are further participants between the individual optical transmission
paths in this case.
Figure 4.3: Cascading of several DDLS 200 systems
ATTENTION!
If, for example, participant 3 (TN3) of a multi-master bus system wants to exchange data
directly with participant 7 (TN7), then five optical transmission paths are cascaded.
This constellation can also occur if, e.g., a programming device that attempts to access
participant 3 (TN3) is connected to participant 7 (TN7) for maintenance purposes or during
commissioning of a master-slave-system.

4.4 Electrical connection
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 Allen 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.
Figure 4.4: Removing the housing top
The connection compartment in the housing base with the screwed cable glands is now freely acces-
sible.
ATTENTION!
Connection of the device and maintenance work while under voltage must only be carried
out by a qualified electrician.
If faults cannot be cleared, the device should be switched off and protected against acci-
dental use.
Before connecting the device, be sure that the supply voltage agrees with the value printed
on the name plate.
The DDLS 200 is designed in accordance with protection class III for supply with PELV
(protective extra-low voltage with reliable disconnection).
For UL applications: Use is permitted exclusively in Class 2 circuits according to NEC.
Ensure the device is correctly earthed. Unimpaired operation is only guaranteed when the
functional earth is connected properly.

Supply voltage
Connect the supply voltage, including the functional earth, to the spring terminals labeled Vin, GND
and PE (see figure 4.5).
NOTE
The connection terminals Vin, GND and PE are each available twice to simplify wiring
through the supply voltage to other devices.
The functional earth can alternatively be connected at the screw terminal in the housing
base (max. wire cross section 2.5mm2)
If you would like to wire through the supply voltage, you should replace the dummy plugs
on the right side of the housing base with an M16 x 1.5 screwed cable gland and guide the
continuing supply voltage cable through this gland. The housing seal is, in this way,
ensured (degree of protection IP 65).
The housing top can be removed and replaced while under voltage.

0…2VDC: transmitter/receiver
switched off, no transmission
18 … 30VDC: transmitter/receiver
active, normal function
Switch Function
S1 On (Default): The switching input is not
analyzed. The transmitter/receiver unit
is always in operation.
Off: The switching input is analyzed.
Depending on the input voltage, normal
function or transmitter/receiver unit
switched off.

Mounting / Installation (all device models)
18 DDLS 200 Leuze electronic
Switching input
The DDLS 200 is equipped with a switching input IN, via which the transmitter/receiver unit can be
switched off, i.e. no infrared light is transmitted and at the bus terminals the corresponding bus bias
level is present / the bus driver is high impedance.
Input voltage: 0 … 2 V DC: transmitter/receiver switched off, no transmission
(Relative to GND) 18 … 30VDC: Transmitter/receiver active, normal function
For easier operation, the switching input can be activated/deactivated via switch S1:
Position S1: On the switching input is not analyzed. The transmitter/receiver
unit is always in operation (internal preselection of the switch-
ing input with Vin).
Off the switching input is analyzed. Depending on the input volt-
age, normal function or transmitter/receiver unit switched off.
Switching output
The DDLS 200 is equipped with a switching output OUT WARN which is activated if the received sig-
nal level in the receiver drops.
Output voltage: 0 … 2VDC: operating range
(Relative to GND) Vin - 2VDC: Warning or shutoff range
The switching output is protected against: short-circuit, overcurrent, overvoltage, excess temperature
and transients.
NOTE
When transmitter/receiver unit is switched off, the system behaves in the same way as in
the event of a light beam interruption (see chapter 11.4 "Operation").
The switching input can be used, for example, during a corridor change to completely
avoid interference effects from other sensors or the data transmission.
Switch S1 is also present on the device models with M12 connectors.
NOTE
The DDLS 200 is still completely functional when the received signal level drops to the
warning signal level. Checking the alignment, and, if applicable, a readjustment and/or
cleaning of the glass pane leads to a significant improvement of the received signal level.
