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 A with one another within ± A
• 0.01 to ensure that the transmission/reception beams of the two de-
min
vices 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°, resp.) 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 65)
Mount each device with 4 screws ∅ 5mm using 4 of the 5 fastening holes in the mounting plate of the device (see chapter 3.2 "Dimensioned drawings").

4.3 Cascading (series connection) of several DDLS 200 data paths

If two communicating participants (TN) are separated by several optical transmission paths between two participants, then this is called 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 5 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.

Switching input
The DDLS 200 is equipped with a switching input IN (pin 1), 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 resistance.
The upper part of the housing only needs to be removed if the switching input is to be activated/deac­tivated via switch S1 (for further information, see figure 4.4, figure 4.5 and "Switching input" on page 18).
Input voltage: 0 … 2 V DC: transmitter/receiver switched off, no transmission (relative to GND) 18 … 30 V DC: transmitter/receiver active, normal function
For easier operation, the switching input can be activated/deactivated via switch S1 (see chapter
4.4.1, figure 4.4 and figure 4.5): Position S1: On the switching input is not analyzed. The transmitter/receiver
unit is always in operation (internal preselection of the switch­ing input with Vin).
Off the switching input is analyzed. Depending on the input volt-
age, normal function or transmitter/receiver unit switched off.
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.
Switching output
The DDLS 200 is equipped with a switching output OUT WARN which is activated if the receiving level in the receiver drops.
Output voltage: 0 … 2 V DC: Operating range (relative to GND) Vin - 2 V DC: warning or shutoff range
The switching output is protected against:short-circuit, overcurrent, overvoltage,
Note!
The DDLS 200 is still completely functional when the level of the receiving signal 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.

5.1.1 Converting the PROFIBUS model with terminals to M12 connectors

Available as an optional accessory is an M12 connector set, consisting of M12 connector (A-coded, power), M12 connector (B-coded, bus) and M12 socket (B-coded, bus), with ready-made wires (Part No. 500 38937). This can be used to convert the PROFIBUS models with terminals/screwed cable glands to M12 connectors.
Conversion to M12 connectors
1. Remove screwed cable gland 1, 2 and 3 (spanner size = 20mm)
2. Screw M12 plug (power) into the thread of the screwed cable gland 1 that you have just removed and tighten it with spanner SW18.
3. Screw M12 socket (bus) into the thread of the screwed cable gland 2 that you have just removed and tighten it with spanner SW18.
4. Screw M12 plug (bus) into the thread of the screwed cable gland 3 that you have just removed and tighten it with spanner SW18.
5. Connect cables acc. to figure 5.2 and Table 5.1.

Termination for devices with M12 connectors

Note!
If the PROFIBUS network begins or ends at the DDLS 200 (not a continuing bus), the BUS OUT connection must be terminated with the TS 02-4-SA terminator plug, which is available as an optional accessory (see chapter 14.1 on page 67).
In this case, please also order the TS 02-4-SA terminator plug.

5.3 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 • 19.2 kbit/s
• 93.75 kbit/s • 187.5 kbit/s
• 500 kbit/s 1)• 1500 kbit/s
Set the transmission rate in accordance with the table printed on the connection circuit board (see figure 5.1). The default setting is:
• 9.6kbit/s for DDLS 200 PROFIBUS device models with terminal connection
• 1500kbit/s for DDLS 200 PROFIBUS device models with M12 connection

PROFIBUS / RS 485 changeover (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 + 1T
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.

9.3 Device configuration DeviceNet / CANopen

9.3.1 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.

9.3.2 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.

9.4 Wiring

• The ends of the bus lines must be terminated between CAN_L and CAN_H for each physical bus
segment (see figure 9.9 ).
• Typical CAN cables consist of a twisted-pair cable with a shield that is usually used as CAN_GND.
Only use cables recommended for DeviceNet or CANopen.
• The ground reference CAN_GND must only be connected to earth potential (PE) at one place on a
physical bus segment (see figure 9.9).

Response upon interruption of the optical data transmission path

Figure 9.12: Interruption of the optical data transmission path
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, ...).

"Monitoring" of subscribers

If a 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
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 DDLS 200 45
TNT 35/7-24V
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. CAN frames are temporarily stored (64 frames for baud rates ≥ 800kbit and 128 frames for baud rates < 800 kbit).
2. If between 30% and 70% of the memory is occupied, the "BUF" LED flashes
3. If > 70% of the memory is occupied, the "BUF" LED is constantly illuminated
4. 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.

9.7 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.

The maximum delay is dependent on various boundary conditions:
• bus load
• message priority
•history
• sorting active / not active
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 configuring the system.

9.7.3 Synchronous messages

All subscribers receive the message, but not simultaneously. Should therefore not be used for synchronization purposes. All subscribers receive the message, but not simultaneously.
The message is transmitted to all subscrib­ers. Subscribers in another segment, e.g. Segment 2, receive this telegram with a time delay and are, thus, not synchronized with the subscribers in Segment 1. All subscribers receive the message. Sub­scribers in a segment other than the producer of the message receive this information with a time delay. An error in the timing information results: min. T

9.7.4 Other implementation notes

Bus expansion is maximized by dividing into two sub-segments
• without data transmission equipment:1 x max. bus length
• with data transmission equipment:2 x max. bus length + optical path
With the DeviceNet, make certain that subscribers with large quantities of data or long response times are as high as possible in the scan list.
1. Make certain that subscribers with large quantities of data or long response times are as high as possible in the scan list. If not, the order should be rearranged.
2. Increase interscan delays until all responses are received within a single scanning cycle.

10 Ethernet

The Ethernet model of the DDLS 200 has the following features:
• Operating ranges 120m, 200m, 300 m
• Supports 10 Base-T and 100Base-TX (half and full duplex)
• Effective data transmission with 2Mbit/s full duplex
• Supports autopolarity and autonegotiation (Nway)
• Supports frames up to 1522 bytes in length
• The DDLS 200 for Ethernet does not occupy a MAC address
• Protocol-independent (transmits all protocols that are based on TCP/IP and UDP, e.g., Ethernet, Modbus TCP/IP, ProfiNet V1+V2)
• RJ-45 connector (a separate screwed cable gland is used to achieve protection class IP 65)
• M12 connectors, D-coded
• Conversion of 10Base-T to 100 Base-TX and vice versa is possible
• Internal 16 kByte message memory (sufficient for approx. 250 short telegrams)
• Increased network expandability owing to optical data transmission:
• without optical data transmission = 100m
• with optical data transmission = 2 • 100m + optical transmission path
• It is possible to cascade several DDLS 200 (see chapter 4.3)

10.3 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.

10.6 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, 10 Base-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 M 12 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. 2 Mbit/s.

The optical data path has a maximum data rate of 2 Mbit/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 upstream switch:
The upstream switch ensures that only messages for nodes located downstream of the optical data transmission path are transmitted. 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.

Commissioning / Operation (all device models)

11.3 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 may be two causes: a hardware error has oc­curred or the transmitter/receiver unit has been switched off via the IN switching input ("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 optimization 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. Both devices are located close to one another (> 1m). Ideally, the bar graphs of both devices display maximum end-scale deflection.
2. Switch both devices to "Manual" (MAN) by pressing the button for a relatively long time (> 2 s). Data transmission remains active, only the internal cut-off threshold is changed to the warning threshold (yellow LEDs).
3. 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.
4. Briefly press the button to switch both devices to the "Adjust" operating mode (ADJ). Data transmission remains interrupted.
5. The devices can now be individually aligned. The result of the alignment can be read directly in the bar graph.
6. 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.
7. 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)

11.4 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 ana­lyzing the switching output OUT WARN (with the INTERBUS fiber-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!
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.

12.1 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.

13 Diagnostics and Troubleshooting

13.1 Status display on the device

The LEDs on the control panel of the DDLS 200 provide information about possible faults and errors. The descriptions of the states of the DDLS 200's LEDs are found for
• all models in chapter 11.1
• the model PROFIBUS / RS 485 in chapter 5.4
• the model INTERBUS 500kbit/s / RS 422 in chapter 6.3
• the model INTERBUS 2Mbit/s fiber-optic cable in chapter 7.3
• the model Data Highway + / Remote I/O in chapter 8.3
• the model DeviceNet / CANopen in chapter 9.5
• the model Ethernet in chapter 10.5
Note!
The INTERBUS 2Mbit/s fiber-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

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.
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.
