Application examples
Linear structure
The repeater can be used to create network structures that
are tailored to the relevant application.
The limits set by the PROFIBUS standard are therefore
extended. The standard defines the following basic
specifications:
– Up to 32 devices per potential segment
– Only line structures
– Maximum bus cable length: 1200 m
– Bus cable termination at the start and end of the bus
cable
Please note that in each potential segment,
the port of the repeater must be considered as
an electrical device.
Max. of 30 devices
= Switch on bus terminating resistor
Figure 2
Branch
PROFIBUS 12 mbps
100m
Max. of 30 devices
Line structure
Bus segmentation with repeaters makes it possible to
multiply the permissible coverage of the network and to
extend the number of devices.
The full number of devices from the PROFIBUS
specification (n x 32) applies in each potential segment.
Higher transmission speeds can also be supported by
subdividing into shorter segment lengths.
100m
Example: normally, a PROFIBUS segment with a length of
200 m could only be operated at a data rate of 1.5 Mbps. If
you use a repeater after 100 m, the possible data rate is
12 Mbps.

Tree structure
Mixed/network structures, star, and tree structures can be
created using the repeaters. The repeaters can be extended
using PSI-MOS-PROFIB/FO... fiber optic converters.
In addition, the repeaters can be combined and therefore
configured to form a modular PROFIBUS hub.
6.1
Bit retiming
PROFIBUS signals with a bit distortion of up to 35 % can be
reliably detected using the bit retiming function and are
converted to their original bit form before being transferred
to the next segment.
This data processing function means that a virtually
unlimited number of repeaters can be connected without an
impermissible level of bit distortion.
6.2
Bit oversampling
The bit oversampling function can be used to detect and
filter disturbances. This means that these disturbances are
not transferred to the next segment.

take this bit delay into account when configuring the lines.
If several repeaters are connected to form a star structure,
there is no additional bit delay when distributing the data
signal via the DIN rail connector.
The corresponding bit delay must only be taken into
consideration when the telegram is received at port A or
port B. The direction (master or slave) from which the
telegram is received at the repeater is therefore not
important.

Cable configuration
•
The cable configuration is only necessary if
the repeater is operated in FILTER mode
(DIP 5 = OFF). In this case, the bit delay of
11 bits must be taken into consideration in the
cable configuration of the control system.

Configuring the network parameters in STEP 7
Open the “Properties-DP” dialog box and click on
“Properties”.
Select a subnetwork and click on “Properties”.
Switch to the “Network Settings” tab and click on
“Options”.
Switch to the “Cables” tab.
Data transmission cables and network components lead to
signal delays. The following section provides support when
calculating the necessary network parameters.
The configuration of network parameters is described using
a practical example with STEP 7® software.
The following data is required for configuration:
– Number of repeaters
– Total length of all copper cables
Tslot_Init = a + b x L + 22 x N
Tslot_Init = Minimum slot time in bit periods
a, b
= Length parameter (see table)

Assembly
Combined assembly
Observe the snap-in direction of the device
and DIN rail connector: snap-on foot below
and plug on the left.
CAUTION: Electric shock
The device is designed exclusively for SELV
operation according to IEC 60950/EN 60950/
VDE 0805. The device may only be
connected to devices, which meet the
requirements of EN 60950.
A connection station must not consist of more
than ten devices.
A
NOTE: Malfunction
Use a grounding terminal block to connect the
DIN rail to protective earth ground. The
devices are grounded when they are snapped
onto the DIN rail (installation according to
PELV).
This ensures that the shielding is effective.
Connect protective earth ground with low
impedance.
