3.3 Safe Use
Before mounting
• Read and observe the safety notes in this manual.
• Ensure that the contents of this manual are fully understood by the personnel in
charge.
• Always consult with R. STAHL Schaltgeräte GmbH if using the device under operating
conditions which are not covered by the technical data.
• We are not liable for damage caused by incorrect or unauthorised use of the device or
by non-compliance with this manual.
For assembly and installation
• Have mounting and installation performed only by qualified and authorised persons
(see "Personnel qualification" section).
• During installation and operation, observe the information (characteristic values and
rated operating conditions) on the type plates, data plates and information signs
located on the device.
• Only connect the device to equipment which does not carry voltages higher than
253 V AC (50 Hz).
• The safety characteristic values of the connected field devices must correspond to the
specifications in the data sheet or in the EU Type Examination Certificate.
• The laser diode of the fibre optic isolating repeater emits laser radiation.
The laser beam is emitted through the emitting diode (TD-A, TD-B) or through the end
of the fibre optic cable. According to EN 60825-1, the laser diode is assigned to the
laser class 1M. In order to avoid eye injuries, do not view the laser beam directly with
optical instruments (e.g. magnifiers, microscopes).
Additionally for Type 9186/12
• Install the device in Zones 1, 2, 21, 22 or outside of hazardous areas.
• When used in Zones 1, 2 or 22, the device must be built into an enclosure which
corresponds to the requirements of IEC/EN 60079-7, IEC/EN 60079-15 or
IEC/EN 60079-31.
• When used in Zones 2 and 22, the intrinsically safe devices of Zones 1, 0, 21 and
20 can be connected to the intrinsically safe signal circuits.
• Separate non-intrinsically safe circuits from intrinsically safe circuits.
• Electric circuits with the "Ex i" type of protection can no longer be operated as circuits
with this protection type after being operated with circuits with other types of protection.
• Interconnecting several devices in a single intrinsically safe circuit can result in
different safety characteristic values. This may impair intrinsic safety!
• Observe the system certificate (PTB 04 ATEX 2089) and operating instructions for the
Sub-D connector (94 900 02 22 0) if the RS-485-IS interface is to be connected with
other fieldbus devices to form a fieldbus system.
• Avoid making connections or disconnections at Ex e terminals 1 and 2 for auxiliary
power supply while the system is energised. After switching off the supply voltage,
wait one minute before disconnecting the lines from the device.

Additionally for Type 9186/.5
• Install the device in Zones 2, 22 or outside of hazardous areas.
• When used in Zones 2 or 22, the device must be built into an enclosure which
corresponds to the requirements of IEC/EN 60079-15 or IEC/EN 60079-31.
• Only connect the FO interface with devices that correspond to the Ex op is type of
protection. Devices connected with the fibre optic isolating repeater may be installed
in Zones 2 or 22 or in the safe area.
• Only install the device in a de-energised state.
Commissioning, maintenance, repair
• Only have commissioning and repairs performed by qualified and authorised persons
(see "Personnel qualification" section).
• Before commissioning, make sure that the device is not damaged.
• Only perform maintenance work described in this manual.
3.4 Modifications and Alterations
DANGER
Explosion hazard due to modifications and alterations to the device!
Non-compliance results in severe or fatal injuries.
• Do not modify or alter the device.
No liability or warranty for damage resulting from modifications and
alterations.

4 Function and Device Design
4.1 Function
Application range
The fibre optic isolating repeater is used in hazardous areas to set up FO network
structures.
It enables transfer of asynchronous UART protocols such as Profibus DP and
Modbus signals over long distances.
Mode of operation
The signals are transmitted from an intrinsically safe RS-485-interface according to
PNO specification to an intrinsically safe optical interface (Ex op is).
DANGER
Explosion hazard due to improper use!
Non-compliance results in severe or fatal injuries.
• The device may only be used according to the operating conditions
described in this manual.
• Use the device only for the intended purpose specified in this
manual.

• Values a and b are dependent upon the data rate and bus profile used (see table).
Adjust the slot time TSL in the system configuration accordingly.
• Confirm that the minimum protocol processing time MIN TSDR amounts to at least
11 bit times (MIN TSDR ) 11).
Table: Programming parameters for linear structures
Operating in redundant ring
A ring structure is made of at least three type 9186 devices.
Calculate the minimum slot time TSL min according to the rule
TSL min = a + b x L + 2 x N
where:
TSL min: the minimum SLOT time in bit times
N: number of FO converters
L: Network reach in km
The data transmission lines and network components may cause signal
delays. The bus parameters must therefore by adjusted using appropriate
project engineering software. The defined maximum network reach must also
be taken into account.

• Note the maximum ring reach, which depends upon the data rate and number of
devices in use according to the table.
Example:
• Number of FO converters in the ring: 6
• Speed: 500 kbps
• Permitted total reach: 14.4 km
• Total installed length of the FO: 9.98 km => O. K.
Slot time to be set: TSL min = a + b x L + 2 x N = 211 + 9.98 x 5 + 2 x 6 = 273 bits
6.2 Modbus / ServiceBus
Calculate the signal delay dT according to the rule
dT= b x L + 2 x N
where:
Signal delay in bit times for a complete signal cycle
b: Length parameter (table)
L: Network reach in km
N: Number of fibre optic isolating repeaters
For the FO ring to function correctly, dT must be smaller than the shortest frame in bits.
Table: Correlation of data rate and length parameter b
Data transmission lines and network components may cause signal delays.
If necessary, these must be taken into account when adjusting the TIME-OUT
times of the bus system used.

ServiceBus
The number of devices is limited to a maximum of 24 when operating in ServiceBus
mode.
Table: Ring size in ServiceBus operating mode (9.6 kbps data rate)
6.3 PROFIsafe
The PROFIsafe devices differ from the standard PROFIBUS devices by assigning
4 bytes of the possible payload range of a PROFIBUS frame for the additional PROFIsafe
information (frame ID, CRC, etc.). This additional data is analysed by the master
(F-Host).
To the type 9186 fibre optic isolating repeater, the PROFIBUS frames are transmitted
transparently, irrespective of the contents of the data. All type 9186 fibre optic isolating
repeaters can consequently be operated in PROFIBUS networks with and without
PROFIsafe devices.
Also note the Watchdog monitoring, configured for all PROFIsafe devices in the control
system. In the event of very large fibre optic networks or radio transmission of PROFIBUS
data, Watchdog monitoring can be triggered. In this case the configured Watchdog time
must be adjusted correspondingly.

Based on the state-of-the-art technology, PROFIsafe devices and
PROFIBUS standard devices can be operated simultaneously in one
PROFIBUS network. It is commonly referred to as PROFIsafe in PROFIBUS
(not to be confused with PROFIsafe in PROFINET). More information on this
topic can be found in the relevant standards of the PNO.
