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.

4.1 Mounting instructions

Mounting

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.
