ProfiHub F1 is a registered trademark of PROCENTEC. Other products or company names are or may be

The interface modules ProfiHub F1 couple PROFIBUS-DP or PROFIBUS-FMS two-wire-segments (RS-485) via optical fibres. The module can work as a ring module or work in a Line- or Point-to-point-structure. This can be set
by a DIP-switch.
They are equipped with two supply voltage inputs to provide redundant power supply. The integrated error
relay can be used to indicate malfunctions.
The PROFIBUS-data rates 9,6KBit/s, 19,2KBit/s, 45,45KBit/s, 93,75KBit/s, 187,5KBit/s, 500KBit/s, 1,5MBit/s,
3MBit/s, 6MBit/s and 12MBit/s are automatically detected by the module.
Power off the devices, which will be connected by using the fiber optic system.
Snap the system onto the DIN EN rail and check the correct holding!
Use only the correct optical connectors for the fiber optic system. Using incorrect connectors can
cause damage to the fiber optic system. Take care that connectors with a latch can only be mounted
in a defined position.
Don't stare into the optical cable or the transmitter of the fiber optic system. Visible and non-visible
light (depending on its wavelength) of the optical transmitter can cause eye-damages!
Connect the fiber optic system by using the correct fiber optic cable. Take care that you always have to connect
an optical transmitter and an optical receiver.
Use the plugs to save the unused optical receiver and transmitter against impurity.
Don't bend the fiber optic cable! Please refer to the specifications of the cable manufacturer.
Otherwise the fiber optic cable can be damaged or the communication will be disturbed.
Power on the devices. Please use a power supply of 12-30VDC, connected to the terminals marked with VDC1,
VDC 2 and GND. Note, that VDC 1 and VDC 2 are redundant power inputs with reverse voltage protection.
Function of the DIP-Switch :
SW1 to SW3 : PROFIBUS termination between “A” and “B” line
SW4 : Choose Ring or Line / Point-to-Point structure
SW5 : Disables Fiber Port CH2
SW6 : Disables Fiber Port CH1
Function of the Status-LEDs:
VDC : Power Supply at VDC1 or VDC2
FAIL : Failure group signal and failure relay opened
Status : No data rate detected yet or bus-error (to long data-
frame or to long duration of a zero). Changed PROFIBUS-wires can be detected by the status-led when the
termination of the ProfiHub F1 is turned off (DIP-switches 1 to 3).
Rx : Data being received. A received frame is only shown at the Rx-led of the channel where it arrives first. Thus
it can happen that although working in a ring, only one of the Rx-leds lights or both Rx-leds of the ProfiHub F1
are blinking.
Function of the Status-LEDs Fiberview:
Fail : Received optical signal failed
Limit : System reserve reached
Link / Act : Transmitting or receiving data
Failure Relay: Terminals K1 to K3 are connected to a potential free relay. If the optical connection works
without failures the relay gets active and closes K1 to K2 and opens K2 to K3. If the optical connection is
disconnected or power supply at VDC1 or VDC2 fails, the relay will get inactive and K1 to K2 opens and K2 to K3
closes
Function of K1 – K2: Potential free failure relay contact NC.
Function of K2 – K3: Potential free failure relay contact NO.
Systems with 2 FX-Ports always have transceiver CH1 as the upper one.
Start-up: After having applied the supply voltage the module start the data rate detection. When the data rate
is detected, the transmission of the received data is started.
Thus, at slow data rates and in ring structures with many converters closing the ring at start-up can take some
seconds. As well, after having changed the data rate of the system, the ring may take some seconds before
adjusting the new data rate.
The fail-led of the PROFIBUS-connector lights until the first data rate is detected. After the data rate detection
it only lights to show bus-errors.
To meet the required values a PROFIBUS-cable has to be used and modules and cable-shield have to
be grounded properly.
POF-connection:
To connect the POF cable into the Optolock, the end of the cable is cut cleanly. Use a POF-Cutter to make a
straight cut in an angle of 90° at the chose position of the cable. After that the end of the two strands are
separated. Then the strands are inserted into the two holes in the termination housing, which is then pressed
close to hold the POF in place.
Pay attention on the bending radius of the optical cables while installing them and check the temperature
range of the used plugs.
When planning a ring structure the following things have to be considered:
• Set DIP-switch 4 ON, 5 and 6 to position OFF
• The minimum response time of the slaves (min T
• The slot time or the PROFIBUS (T
) must be adjusted to a value high enough to guarantee that the answers
SL
of all slaves are at the master within the slot time, even when an optical connection is broken. The
minimum slot time depends on the data rate, the length of the optical fibre and on the number of ProfiHub
F1 in the ring. It can be calculated using the formula below

: maximum response time of the slaves.
SDR
: Length of the whole optical fibre in the ring. The two longest branch lines – if there are any –
should be added to the length of the fibre optical in the ring.
: Constant considering the bit times per km fibre optical cable (see table)
LWL
: Number of ProfiHub F1 in the ring.
n
DL
: Constant considering the delay time (in bit times) of one ProfiHub F1 (see table below).
A ring topology must be connected from CH1 to CH1 and CH2 to CH2. Only with an uneven number
of FO modules, the cables may be connected from CH1 to CH2 and CH2 to CH1 (only once per ring).
As standard, the system has a clip for 35mm DIN rails according to DIN EN 60175.
For mounting the system please engage it onto the rail at the bottom side (see left picture), press it against the
spring force to the top (1) and then towards the mounting plate (2). The system latches as shown in the picture
at the right. Please refer to the above mentioned steps in reverse order to demount the switch.
As an option, a wall mount kit is also available. If the system should be fixed onto the wall, the clip for DIN rail
mount has to be unscrewed first.
