1.3 Short description

Where data have to be transmitted to and from moving objects, optical data transmission systems provide an ideal solution.

With the DDLS 200 Series, Leuze electronic offers optical, high-performance data transmission systems. The data transmission units are robust and are not subject to wear.

A DDLS 200 data transmission system consists of a set of two transmission and reception units: e.g. DDLS 200/200.1-10 and DDLS 200/200.2-10.

General Information

Optical data transmission on

two frequencies

Features of the DDLS 200

The fact that bus systems are found in nearly all areas of industry places high demands on data transmission 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, 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

• INTERBUS 500kbit/s, RS 422 general, copper cable

• 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 f

and frequency f

on the control panel.

DDLS 200/XXX.1-YY DDLS 200/XXX.2-YY

Figure 1.1: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 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.

4.4 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 (P tective E 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.

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 provided double 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. core cross section 2.5mm

If you would like to wire through the supply voltage, you should replace the filler 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 (Protection Class IP 65).

The housing top can be removed and replaced while under voltage.
