Description The PROFIBUS Repeaters are designed to be used in optical PROFIBUS field bus networks according to IEC 61784. They enable electrical PROFIBUS interfaces (RS 485 level) to be converted into optical PROFIBUS interfaces and vice-versa. By profiting from the familiar advantages of optical transmission technology, the repeaters can be integrated into existing PROFIBUS field bus networks.
Page 12
Port Depending on a device variant, each device has 2,3,4 mutually independent ports (channels), which in turn consist of a transmitting and a receiving component. The electric ports are a 9-pole D-Sub socket (female). A PROFIBUS bus segment can be connected to this ports. The optical ports are BFOC/2.5 (ST ®) sockets.
Page 13
Power supply The power supply is 24 V direct current. To improve the operating safety, a redundant operating power supply consisting of two separate sources can be used. For this purpose, you must connect the two supply voltages to two different terminals of the 8-pin screw-type terminal block.Both connections are uncoupled by means of diodes to prevent reverse voltage supply or destruction through incorrect pole connection.
Page 14
Measuring output One measuring output is available for each optical port. The measuring output is connected to the 8-pin screw type terminal block. +24V Fault +24V Configuration You can easily set the configuration to meet your specific requirements by means of DIP switches, which can easily be operated from outside.

The transmission rate is set automatically as soon as the OZD Profi 12M ...
Operating mode related functions The operating mode is set using switches located on the front of the repeater. A sticker attached to the side of the repeater provides assistance with the settings. The OZD Profi 12M ... must be switched off when switching over DIP switches.
Page 17
Segmentation If an echo monitoring error or a frame falsification arises at an optical port, the repeater assumes that the line is faulty and blocks this port for user data. The connected field bus partial network is then segmented (cut off). This segmentation causes the repeater at the other end of the optical fiber to be segmented as well.

The following ambient conditions must be fulfilled to ensure that the network configuration functions correctly: The operating mode ”Redundant optical ring“ must be set at both optical ports of all the OZD Profi 12M .. All repeaters in a ring must be connected to one another by fiber lines. The ring may not include an RS 485 bus line.
Installation guidelines Electromagnetic compatibility (EMC) Electromagnetic compatibility (EMC) covers all aspects regarding the effects of radiated and received electrical, magnetic, and electromagnetic emissions. In order to prevent interference in electrical systems, these effects must be reduced to a minimum. The structural design and correct connection of bus lines as well as the interference suppression of switched inductances play a major role in limiting interference.
Arrangement of devices and cables 3.3.1 Reducing interference by providing adequate space: A simple yet effective way of reducing interference is to separate devices and cables causing interference from those affected by interference. Inductive and capacitive interference injection decreases by the square of the distance between the elements concerned.
Note: If differences in potential occur between the grounding points, an inadmissibly high compensating current could flow across the shielding connected at both ends. Never eliminate this problem by removing the shielding from the bus line. The following solution is permissible: Lay an additional equipotential bonding cable parallel to the bus line.
Laying cables inside of buildings Laying cables within control cabinets If a repeater is installed within a control cabinet, the cable shield of the incoming bus cable should be electrically connected to a grounding rail as close as possible to the cable lead through using a shield grounding clamp or similar.
