3 Device description

3.1 Device overview

3.1.1 General information

The DDLS548i optical data transmission system transmits Ethernet network data on the basis of TCP/IP or
UDP transparently and without contact or wear via infrared light.

NOTICE

The DDLS548i devices are designed as PROFINET participants. During commissioning, the
devices are configured with a “name” during device naming as well as the corresponding IP ad­dress. Using standardized GSDML structures, the DDLS548i can itself supply information about
the device to the control (see chapter 7 "PROFINET").

A transmission path consists of two mutually opposing devices.

• One device is designated with “Frequency F3", the other with “Frequency F4".

• The devices can also be assigned via part number code DDLS5XX…3… and DDLS5XX…4….

Each device is delivered with an individual MAC address. The MAC address can be found on the name
plate and on an easily removable "Address Link Label” (see chapter 9.2.2 "MAC address") that is also at­tached to the device.

The devices are equipped with a web server for remote diagnosis.

3.1.2 Protocol-specific characteristics of the DDLS548i

The integrated switch to the web server of the DDLS548i for remote diagnosis can lead to restricted perfor­mance with some TCP/IP or UDP protocols.

It is particularly important for the user to check the usability of the DDLS548i for the following data trans­mission scenarios:

• Transmissions that make extremely high demands of real time

• Transmissions with extremely narrow specifications with regard to particular protocol architecture, delay
times and jitter tolerances.

NOTICE

Transmission problems with TCP/IP and UDP protocols!

It is the user's decision whether the DDLS548i is usable. LeuzeelectronicGmbH+Co.KG can­not accept any liability for any transmission problems that occur which are attributable to the
above-mentioned causes.

The following TCP/IP and UDP protocols must be checked individually. The list does not claim to be com­plete.

• PROFINET Profisafe

• PROFINET IRT

• All safety protocols

• The DDLS548i cannot be used in EtherCat networks.

4 Mounting

The optical data transmission systems of series DDLS500 support simple and quick basic assembly of
both mutually opposing devices.

• An optical data transmission system, consisting of two devices, involves mounting each of the devices
on mutually opposing, plane-parallel, flat and usually vertical walls with unobstructed view of the oppos­ing device.

• For installation with an integrated laser pointer (optional) see chapter 4.2 "Mounting with alignment
laser and level".

• For installation without the optional laser pointer see chapter 4.3 "Mounting without alignment laser".

NOTICE

Interruption of data transmission!

Data transmission is interrupted if the beam spread of the transmitters is no longer sufficient for
maintaining the optical link.

Ä Make certain that data transmission is not interrupted, e.g., by jolts, vibrations or inclination,

while moving a mobile device due to irregularities in the floor or path.

Ä For mobile arrangement of a device, ensure good tracking stability.

NOTICE

Select the mounting location!

Ä Make certain that the required environmental conditions (humidity, temperature) are main-

tained.

Ä For low ambient temperatures, e.g., in cold stores, use data transmission systems with inte-

grated heating.

Ä Avoid rapid temperature changes at the data transmission system to prevent condensation.
Ä Protect the data transmission system from direct sunlight.
Ä For parallel mounting of data transmission systems and other optical measurement systems,

make certain that the minimum distance between the systems is maintained (see chapter

4.5 "Mounting distance for parallel operation of data transmission systems", see chapter 4.6
"Mounting distance for parallel operation with AMS300/AMS200 laser measurement sys­tems", see chapter 4.7 "Mounting distance for parallel operation with DDLS200 data trans­mission system").

NOTICE

Installation for devices with an operating range of 200m.

Ä Always install the Frequency F4 device as stationary device for devices with an operating

range of 200m (DDLS5XX200…).

NOTICE

You will achieve greater flexibility during basic installation and fine adjustment if you mount the
devices on C profile rails.

NOTICE

If the device is mounted instead of a DDLS200, use the adapter plate – to be ordered sepa­rately – if necessary (see chapter 13.3 "Other accessories").

4.2 Mounting with alignment laser and level

The optional alignment laser simplifies mounting of the mutually opposing devices.

Leuze electronic DDLS 548i 24

• The alignment laser consists of an integrated laser with special beam optics. In addition, a level is inte­grated in devices with alignment laser.

• Alignment laser, level, transmission optics and installation in a device housing form an axially parallel
unit.

• The laser spot of the alignment laser shows the installation position of the mutually opposing device.

4.2.1 Horizontal mounting (travel axis) with the alignment laser

A drilling template is included with the packaging.

all dimensions in mm

Fig.4.1: Drilling template

NOTICE

When performed using the drilling template, the described mounting procedure results in a set­up with the housings of the devices offset relative to one another (see figure). The transmitted
beam of one device is thereby aligned with the center of the receiver optics of the mutually op­posing device.

Fig.4.2: Mounting with offset housings

Overview:

• The alignment laser projects a target spot on the opposing side.

In addition to the target spot, the beam optics produce four individual laser spots that are projected on
the floor.

• The device is aligned vertically and horizontally with two alignment screws using the integrated level
and the laser spots that are projected on the floor.

• The second device is mounted on the horizontally opposing target spot with the aid of the supplied
drilling template.

Ä Depending on mechanical conditions, mount the stationary or mobile device with four M5 screws via

the fastening holes in the mounting plate of the device.

ð Check the vertical mounting with a separate level.
ð Place the level on the edge of the mounting plate.

Ä Connect the device electrically (see chapter 5 "Electrical connection"). The AUT LED (continuous light)

indicates that the start-up phase of the device after "POWER on" has been concluded.

ð After the start-up phase, the operating mode can be changed.

Ä Switch on the alignment laser. Activate the LAS (Alignment laser) operating mode to switch on the

alignment laser (see chapter 6.1 "Setting the operating mode").

NOTICE

Data transmission is active while changing the operating mode and with activated alignment
laser.

The alignment laser projects four spots along a straight line on the floor and a target spot on the opposing
wall.

The distance of the laser spots is dependent on the mounting height of the device. The values in the table
will help you find the laser spots on the floor.

For marking and for better visibility of the laser spots on the floor, four self-adhesive labels are included in
the package.

NOTICE

The integrated alignment laser, the level, as well as the device transmitter are optimally
matched to one another ex works. Minimal mechanical tolerances are, however, unavoidable
and generate a very small error angle. The use of the alignment laser is therefore limited to a
maximum distance between the devices.

used as a function of the mounting height of the device.

systems

The mounting of an AMS 300/AMS 200 laser measurement system does not affect data transmission if the
devices are correctly aligned.

• The reflector size of the AMS300/AMS200 determines the minimum mounting distance of the device
to the AMS.

Reflector sizes from 200x200mm to 1000x1000mm are permissible.

Details on the permissible reflector types can be found in the "Technical description" of the AMS300/
AMS200.

4.8 Cascading (series connection) of multiple data transmission systems

If there are multiple optical data transmission paths between two participants (TN), one speaks of cascad­ing.

1 Optical data transmission path 1

2 Optical data transmission path 2

Fig.4.14: Example: Cascading of multiple data transmission systems

Cascading the devices

Cascading is possible if the specifications of the protocols to be transmitted are not violated with respect to
delay times or jitter tolerances (see chapter 3.1.2 "Protocol-specific characteristics of the DDLS548i").

Due to the very short delay times of the devices, cascading is possible without problem for very many Eth­ernet protocols.

For transmission protocols that are very tightly specified with respect to delay times and jitter tolerances
(e.g., for synchronous transmissions), the user must check the suitability of the devices individually.

• Protocol propagation times:

Constant delay time per path (2 devices): 5µs

6.2 Fine adjustment

6.2.1 General procedure

Fine adjustment of the data transmission must be carried out after installation.

Prerequisites:

• The devices are mounted mutually opposing one another, are electrically connected and are roughly
aligned (see chapter 4 "Mounting").

• The devices are opposite one another at a close distance (>1m). The SIGNAL QUALITY indicator
shows at least one or two green LEDs on both devices.

Perform fine adjustment

There are two processes for performing the fine adjustment:

• The patented single-handed adjustment (SHA) procedure makes it possible for a single person to moni­tor the "Signal Quality" and adjust the transmitter (see chapter 6.2.2 "Fine adjustment with the single­handed adjustment (SHA) process").

• The alternative procedure requires two people (see chapter 6.2.3 "Fine adjustment without the single­handed adjustment (SHA) process").

• One person monitors the "Signal Quality".

• The second person adjusts the transmitter at the mutually opposing device.

Decide which of the two processes to use; explanations can be found in the following chapters.

Starting up the device

6.2.2 Fine adjustment with the single-handed adjustment (SHA) process

The SHA process is a standard function that is implemented in every device. With the SHA process, you
can perform the fine adjustment with just one person.

Ä Activate the MAN (Manual) operating mode on both devices (see chapter 6.1 "Setting the operating

mode").

Ä Enter a travel command for the travel axis or lifting axis to the end of the transportation path or move

the axis manually or in automatic mode to the end of the transportation path.

Ä Data transmission is automatically deactivated when the last green LED in the SIGNALQUALITY dis-

play goes out.

ð The travel axis or lifting axis is normally stopped automatically if data transmission is interrupted. If

not, stop the axis manually.

ð One orange LED must still be illuminated in the SIGNAL QUALITY indicator.

Ä Activate the ADJ operating mode (alignment) (see chapter 6.1 "Setting the operating mode").

NOTICE

If the MAN operating mode (manual) is activated on both devices, the mutually opposing device
is also switched to the ADJ operating mode (alignment) upon switching to the ADJ operating
mode (alignment).

Adjust the first device as follows:

Ä Rotate the upper alignment screw to the right until the last green LED on the SIGNAL QUALITY indica-

tor switches off (see chapter 3.1.1 "Device construction", point 11).

Ä Then rotate the alignment screw to the left until the last green LED on the SIGNAL QUALITY indicator

switches off. Count the number of rotations.

Ä Then rotate the alignment screw half the number of rotations that was counted to the right again.

ð Data transmission is now vertically aligned in the exact center.

Leuze electronic DDLS 548i 44

Starting up the device

Ä Rotate the lower alignment screw to the right until the last green LED on the SIGNAL QUALITY indica-

tor switches off (see chapter 3.1.1 "Device construction", point 12).

Ä Then rotate the alignment screw to the left until the last green LED on the SIGNAL QUALITY indicator

switches off. Count the number of rotations.

Ä Then rotate the alignment screw half the number of rotations that was counted to the right again.

ð Data transmission is now horizontally aligned in the exact center.

Go to the second device. There, the ADJ (Adjust) operating mode is activated.

Ä Adjust the second device in the same way that the first device was adjusted.
Ä First align data transmission vertically, then horizontally.

ð Both devices are optimally aligned for the current distance.

Ä Repeat the process several times if necessary starting with the second step (“Travel command for

travel axis or lifting axis”) until the maximum transmission distance is reached.

NOTICE

Alignment at maximum transmission distance!

Ä At the maximum transmission distance, The procedure must be carried out for the last time

starting with the fourth step (“Operating mode ADJ”). Only then are the devices optimally
aligned with each other.

Ä Activate the AUT (Automatic) operating mode on both devices (see chapter 6.1 "Setting the operating

mode").

ð The devices are now ready.

NOTICE

At the maximum transmission distance, the SIGNAL QUALITY indicator may be one or two
green LEDs short of end-scale deflection. Data transmission is, however, still active.

6.2.3 Fine adjustment without the single-handed adjustment (SHA) process

For fine adjustment without the SHA process, two people are needed. Both people must communicate with
one another.

• One person monitors the stationary device.

• The second person monitors the mobile device.

Ä Activate the AUT (Automatic) operating mode on both devices (see chapter 6.1 "Setting the operating

mode").

Ä Move the travel axis or lifting axis in the direction of maximum distance.

ð The person at the mobile device and the person at the stationary device each monitor the respec-

tive SIGNAL QUALITY indicator.

Ä Stop the axis as soon as the SIGNALQUALITY indicator on either of the devices no longer shows any

green LEDs.

Adjust the mobile device if the stationary device shows a reduced received signal level (SIGNAL QUAL­ITY).

Ä Rotate the upper alignment screw to the right until the last green LED on the SIGNAL QUALITY indica-

tor switches off at the mutually opposing device (see chapter 3.1.1 "Device construction", point 11).
To do this, communication with the second person is required at the mutually opposing device.

ð Note: The second person on the mutually opposing device notifies you of their "SignalQuality" indi-

cator.

Ä Then rotate the alignment screw to the left until the last green LED on the SIGNAL QUALITY indicator

switches off. Only count the number of rotations.

Ä Then rotate the alignment screw half the number of rotations that was counted to the right again.

the Service operating mode.

7.1 Configuring the PROFINET interface

The DDLS548i is designed as a PROFINET-RT device (Real Time; acc. to IEEE802.3). It supports a
transmission rate of up to 100Mbit/s (100BaseTX/FX), full duplex, as well as auto-negotiation and auto­crossover.

• The functionality of the DDLS548i is organized via modules. The modules are part of the Generic Sta­tion Description Markup Language (GSDML) file.

• Each DDLS548i has a unique MAC address (Media Access Control) that is specified on the name
plate. The MAC address (MAC-ID) is linked to an IPaddress during the course of configuration.

The MAC address can be found on the name plate and on an easily removable "Address Link La­bel” (see chapter 9.2.2 "MAC address") that is also attached to the device.

• The Simatic Manager for creation of PROFINET networks links the IP address to a freely selectable de­vice name which may only exist once in the network.

7.1.1 PROFINET‑communication profile

The PROFINET communication profile defines how participants serially transmit their data via the transmis­sion medium. Data exchange with the devices occurs primarily cyclically. For configuration, operation, ob­servation and alarm handling, acyclic communication services are, however, used as well.

Depending on the communication requirements, PROFINET offers suitable protocols and transfer methods:

• RealTime communication(RT) via prioritized Ethernet frames:

• Cyclical process data (I/O data stored in the I/O area of the control)

• Alarms

• Clock synchronization

• Neighborhood information

• Address assignment/address resolution via DCP

• TCP/UDP/IP communication via standard Ethernet TCP/UDP/IP frames:

• Establishing communication

• Acyclic data exchange, i.e., transfer of various types of information:

7.1.2 Conformance Classes

PROFINET devices are categorized into conformance classes to simplify the evaluation and selection of
the devices for the users.

The DDLS548i corresponds to Conformance ClassB (CC-B) and can use an existing Ethernet network in­frastructure.

The DDLS548i supports the following characteristics:

• Cyclical RT communication

• Acyclic TCP/IP communication

• Alarms/diagnostics

• Automatic address assignment

• Neighborhood detection basic functionality

• FASTEthernet100 Base-TX/FX

• Convenient device exchange without engineering tools

• SNMP support

7.1.3 DDLS548i single-port device

The DDLS548i is registered and certified as a single-port device in accordance with the PNO (PROFIBUS
user organization) device classifications. This classification is stored in the GSDML file of the DDLS548i,
where it cannot be modified.

• A DDLS548i device is shown with a Tx port in the hardware configuration in accordance with this clas­sification (connection of the PROFINET data line).

• Although it is physically present, the Fx port is not displayed in the hardware configuration as the opti­cal link to the mutually opposing DDLS548i device.

PROFINET

Topology editor

When a PROFINET network is created with a topology editor, port-specific networking of the participants is
configured.

Although it is physically present, the Fx port is not displayed in the topology editor as the optical link to the
mutually opposing DDLS548i device.

Fig.7.3: PROFINET topology with DDLS 548i in the topology editor

Behavior of the DDLS548i with manual name assignment, automatic name assignment and
topology detection

• Manual device naming/name assignment

Device naming and name assignment on the DDLS548i takes place unrestrictedly in accordance with
the generally applicable procedure (see chapter 7.3 "Configuring for the Siemens SIMATIC-S7 con­trol"). The DDLS548i is no different from other I/O devices in this respect.

• Automatic name and address assignment during initial commissioning

The networking of all participants can be configured in a port-specific way using the topology editor. If
the installed topology corresponds 1:1 to the configured specification, the name and address of all par­ticipants installed in the network can basically be assigned automatically via the engineering tool (con­figuration tool).

Since the DDLS548i is defined as a single-port device, names and addresses are automatically as­signed as far as the first DDLS548i in the chain.

If automatic name and address assignment is to be continued via the optical link of the DDLS548i, the
following DDLS548i must be made known to the topology editor by means of manual name assign­ment. Once this has been done, automatic name and address assignment continues.

• Device exchange with automatic name assignment

The configured network topology must be prepared and configured for the exchange of participants and
the resulting automatic name assignment:

• A port-specific topology is stored in the control.

• The installed participants correspond to at least CLASS B.

If these prerequisites are fulfilled, an individual participant can be replaced with a new participant.

• The default settings for the addresses must be stored in the new participant (IP address, subnet
mask, gateway address and name).

• The name and address are assigned using the optical link of the DDLS548i.

• The previously configured name is assigned to the new participant automatically when exchanging
a DDLS548i, regardless of whether the DDLS548i was exchanged before or after the optical link.

NOTICE

If several participants need to be exchanged at the same time, the device naming for the new
participant must be carried out manually.

Leuze electronic DDLS 548i 49

• Reading in an existing actual topology

The actual topology installed in the field can be read in using the engineering tool (configuration tool)
and input into the control to provide a valid, port-specific target topology.

• The DDLS548i is read in as a single-port device.

• The optical port of the DDLS548i is not displayed. Nevertheless, all participants are shown in a
port-specific way in accordance with the optical data transmission path, including the DDLS548i.

The actual topology can be defined for the target topology using a DDLS548i data transmission path.

7.2 Starting the device

Start the DDLS548i as follows:

Ä Connect the supply voltage.
Ä Configure the DDLS548i, e.g., for a Siemens SIMATIC-S7 control.
Ä Assign the DDLS548i an individual device name and name the device.

7.3 Configuring for the Siemens SIMATIC-S7 control

The functionality of the DDLS548i is defined via input/output data, which is organized in modules. The
modules are part of the GSDML file. Download the corresponding GSDML file from the Leuze electronic
homepage.

By using a user-specific configuration tool, such as SIMATIC Manager or TIA Portal for the Siemens pro­grammable logic control, the required modules are integrated in a project during commissioning. These
modules are provided by the GSD file.

NOTICE

General information on the GSDML file

The term GSD (Generic Station Description) stands for the textual description of a PROFINET
device model. For the description of the complex PROFINET device model, the XML-based GS­DML was introduced. In the following, the terms "GSD" or "GSD file" always refer to the GS­DML-based format. The GSDML file can support an arbitrary number of languages in one file.
Every GSDML file contains a version of the DDLS548i device model. This is also reflected in
the file name.

In the GSDML file, all data necessary for operating the DDLS548i is described in modules: In­put and output data, definition of the control and status bits.

If parameters are changed in the project tool, for example, these changes are stored by the PLC
in the project, not in the GSDML file. The GSDML file is a certified and integral part of the device
and must not be changed. The file is not changed by the system either.

The functionality of the DDLS548i is defined via modules in the GSDML file. A user-specific
configuration tool is used during PLC program creation to integrate the required modules and
configure them appropriately for their respective use.

When operating the DDLS548i on the PROFINET, all input/output data is occupied with default
values. If this input/output data is not changed by the user, the device operates with the default
settings set by Leuze electronic on delivery. You can find the default settings of the DDLS548i
in the module descriptions.

GSDML file name structure

The file name of the GSDML file is constructed according to the following rule:

GSDML-[GSDML-schema-version]-Leuze-DDLS548i-[date].xml

[GSDML schema version] = Version identifier of the GSDML schema version used, e.g., V2.31

[Date] = Release date of the GSDML file in the format yyyymmdd

This date also stands for the release date of the file.

Example: GSDML-V2.31-LEUZE-DDLS548i

Ä Configure the hardware of the S7 PLC:

• Insert the DDLS548i in your project. The PROFINET system is configured with the help of the hard­ware configuration (HW-Config) of the SIMATIC Manager.

• Assign an IP address a unique device name.

Ä Transfer the PROFINET configuration to the IOController (S7 PLC).

Following successful transfer, the following activities take place automatically:

• Check of device names

• Assignment of the IP addresses that were configured in the HW Config to the IOdevices

• Establishment of a connection between the IOController and configured IOdevices

• Cyclical data exchange

Ä Set the device name.

• The PROFINET device has a unique MAC address that is part of the factory settings. The MAC ad­dress may be found on the name plate of the DDLS548i. Multiple DDLS548i devices are distinguished
by the displayed MAC addresses.

• This information is used to assign a unique, plant-specific device name ("NameOfStation") to the device
via the "Discovery and Configuration Protocol (DCP)".

• Every time the system is started up, PROFINET uses the DCP protocol for the IP address assignment,
provided the IO-device is located in the same subnet.

Ä Assign the device names to the configured IO devices.

• Select the DDLS548i using the MAC address.

• The DDLS548i is then assigned the unique device name. The device name must match the device
name configured in the HW Config.

Ä Assign the IP address to the MAC address (individual device name).

• At this point, assign another IP address (suggested by the PLC), a subnet mask and, if required, a
router address, and assign this data to the named participant (device name).

• From now on, and when programming, only the unique device name (max. 240characters) is used.

Ä After completing the configuration phase, check the device names that have been assigned.

NOTICE

Assign unique device name!

Ä Ensure that the device names are unique and that all participants are located in the same

subnet.

7.4 PROFINET project modules

NOTICE

Overwriting of data by PLC!

Ä Note that the PLC overwrites the data set in the Service operating mode of the webConfig

tool. When switching the webConfig operating mode from Service to Process, all service set­tings are overwritten by the GSDML modules of the control or its default values.

Ä During the configuration phase, the DDLS548i receives data telegrams from the IO con-

troller (master). Before the data telegrams are evaluated and the respective settings are
made, all interface-specific settings are reset to default values. This ensures that the set­tings of modules that are not selected are set to the default values.

NOTICE

You can find the default values of the DDLS548i in the module descriptions.
