1 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. A complete PROFIBUS field bus network
with repeaters in line, star or ring topology, and an arbitrary combination of
these, can also be built up.
Device casing
The device is supplied in a metal housing. You have the option of
mounting the device onto the DIN rail.
Glass fiber technology
The use of glass fiber transmission technology enables a very large
transmission range and ensures optimal protection from EMC effects on
the transmission path and – due to the potential separation – on the
Repeater itself.
Transmission rate
The OZD Profi 12M ... supports data rates from 9.6 kBit/s to 12 Mbit/s.
Redundancy
The redundant ring enables a very high level of transmission reliability.
The redundant operating power supply can further improve the operating
reliability.

12 Installation OZD Profi 12M ...
Release 01 07/2017
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.

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. There is no load
distribution between the sources. With redundant supply, the power
supply unit with the higher output voltage must supply the repeater alone.
Signal contact
A signal contact (relay with unconnected contacts) is used to signal
various disruptions in the repeaters. The signal contact is also connected
to the 8-pin screw type terminal block.

One measuring output is available for each optical port. The measuring
output is connected to the 8-pin screw type terminal block.
Configuration
You can easily set the configuration to meet your specific requirements by
means of DIP switches, which can easily be operated from outside.

1.1 Non operating mode related functions
Transmission rate
The OZD Profi 12M ... support all the transmission rates defined in the EN
50170 standard:
9.6 kBit/s, 19.2 kBit/s, 45.45 kBit/s, 93.75 kBit/s,187.5 kBit/s and
500 kBit/s and additionally 1.5 MBit/s, 3 MBit/s, 6 MBit/s and 12 MBit/s.
The transmission rate is set automatically as soon as the OZD Profi 12M
... receives a frame. The setting or adjustment is dependent on the
transmission rate and the set operating mode. Depending on the OZD
Profi 12M ... this can last up to several seconds.
If the transmission speed has not been recognized, the outputs of all ports
are blocked. If the transmission rate changes during operation, this is
detected by the repeaters, which then automatically adjust their settings
accordingly.
Transfer malfunctions may temporarily occur while the rate is being
altered.
Signal regeneration
The repeaters regenerate the signal form and amplitude of the data
received. This allows up to 122 OZD Profi 12M ... to be cascaded (limited
by the address space in PROFIBUS networks).
Help when setting up
At least one bus subscriber must be switched on and active in order to
check the optical fiber connections during the installation. This bus
subscriber serves as the frame source. The OZD Profi 12M ... act
passively when it is switched on. They recognize the transfer rate from the
frames sent by the bus subscriber. An optical help when putting the
device into operation is provided by the port LED which then lights up.

16 Installation OZD Profi 12M ...
Release 01 07/2017
1.2 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.
1.2.1 Segment monitoring at the RS 485 port
If the operating mode ”Electric channel with segment monitoring“ is set, each
receiver monitors the RS 485 bus segment connected to it for faulty frames
or continuously busy networks. If faulty frames are received by the receiver,
or if the network is busy for longer than the maximum permitted send time,
forwarding of the received signals is blocked until frames can be received
again correctly, or if no signal is received for one second.
The RS 485 bus segment is not monitored in the operating mode ”Electric
port without segment monitoring“. Interference from the electrical segment
affects the entire network.
The following functions are only available for the optical channels. Whether
the functions can be activated depends on the operating mode which has
been set.
Line monitoring with echoes
The repeaters enable the connected optical paths to be actively
monitored for interruptions in the fiber line by means of the functions
”Send echo“, ”Monitor echo“ and ”Suppress echo“.
Send echo
A frame which is received by a repeater via any port is transmitted to all
other ports. If the receiving port is an optical port, the repeater sends the
frame back to the corresponding optical sender.
Monitor echo
If a repeater sends a frame - no echo – to an optical port, the repeater
expects to receive an echo. If the echo is not received after a predefined
time, an echo monitoring error is indicated by a red LED belonging to the
port.
Suppress echo
The relevant receiver is separated from the other ports from the moment
a frame is sent until the echo has been received correctly.

Installation OZD Profi 12M ...
Release 01 07/2017 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. Both repeaters connected to the segmented
field bus partial network send test frames to the segmented ports. These
test frames – which are to be received regularly – can be used by both
repeaters to check the status of the field bus partial network. The
segmentation is automatically lifted as soon as the test frames indicate to
both repeaters that the segmented field bus partial network is no longer
disturbed. If all active bus subscribers are deactivated in a previously
active network, the repeaters are segmented cyclically in order to check
the fiber links to the neighboring repeaters. If there is no frame traffic, but
the fiber links are intact, the port LEDs of the optical ports flash yellow
cyclically.
