1. Short description
AUMA actuator controls with FO connection are intended for use in optical fieldbus
networks.
The FO connection integrated in the electrical connection enables the conversion
from electrical RS-485 signals into optical signals and vice versa.
FO connection behaviour is passive at the bus, i.e.control of AUMA actuators is via
bus is made in the same way as for a connection via copper cables (RS-485).
Contrary to RS-485 based systems, different topologies are possible:
●Line topology
●Star topology
●Redundant loop topology
Apart from the large distances, FO cables offer further advantages:
●In environments with electromagnetic interference
●Lightning arrester or overvoltage protection
●Equipotential earth bonding and earthing
●Galvanic separation of the actuator
●Use of common cable trenches for power and signal cables
●Prevention of interference emissions along the transmission line
This allows for customised solutions for various applications such as water/waste
water industries, tunnelling, power plants, thermal industry or telecontrol engineering.

2. FO connection
2.1 Basic information
Hazardous voltage!
Risk of electric shock.Failure to observe this warning can result in death or serious
injury.
→The connection must be carried out exclusively by suitably qualified personnel.
→Prior to opening: Disconnect both system and device from the mains.
→Observe basic information contained in this chapter.
→Observe safety instructions contained in the operation instructions pertaining
to the actuator.
Eye damage caused by open fibre optic cable ends!
→NEVER look directly into open cable ends or FO cable connections.
Connection or receive problems when ignoring the installation instructions!
→Only using FO cable connection (connector types) with the wiring techniques
indicated in these instructions.
→Only mount connector types with locking mechanisms in the defined position.
→Protect unused FO cable connections against contamination or dust with protec-
tive caps/plugs supplied by the factory.
→Connect incoming FO cable with the optical receiver, the outgoing FO cable
with the optical sender. NOT vice versa!
→Do NOT kink FO cables! Observe bending radius of cable manufacturer.

FO connection

3. Network topologies
When connecting several terminal devices (actuators) in a network, the structure is
called network topology.AUMA offers 3 different network topologies.
3.1 Line topology
Figure 8: Structure for line topology
Max. FO cable range in km (observe technical data!)
[1] Channel 1
[2] Channel 2
[3] Any Profibus DP device
[4] FO coupler at DCS (mandatory)
[5] FO coupler for any Profibus field device
Special features of line topology
The optical signal is converted into an electrical signal at each device. Prior to
transmission to the next device, the electrical signal is converted into an optical
signal.
Interruption of an FO cable (case A) or failure of an FO connection board (case B)
results in a loss of control for the subsequent actuators:
Case A
(standard)
As soon as the electrical connection is removed from the , the FO connection of this
actuator is no longer available. As a consequence, communication with the
subsequent actuators is lost.To prevent this, the FO connection used in the can also
be externally supplied with 24 V DC.
Case B
(option)
As soon as the actuator is switched off (motor voltage), the FO connection board of
this actuator is no longer available. As a consequence, communication with the
subsequentactuatorsislost.Topreventthis,thecompletecanbeexternallysupplied
with 24 V DC.

Network topologies

Information ●Communication of the following devices is monitored by channel 2.In the event
of loss of communication (i.e.no response from the next device), the shows
the following indication: Wrn FOC.
●If the actuator is the last device of the line topology, the monitoring function
should be deactivated (parameter FO cable monitoring M0709 = Off (final devi-
ce).
●Ensure proper termination for RS-485 connection of FO coupler.
3.2 Star topology

Special features of star topology
Failure of an FO cable section or of an actuator's FO connection board has no effect
on the operability of the remaining actuators.
Information ●As all AUMA actuators are operated at the end of the FO cable section and
controlled via channel 1, the parameter FO cable monitoring M0709 should be
set to Off (final device).
●Ensure proper termination for RS-485 connection of FO coupler.

Special features of loop topology
●The interruption of an FO cable between two actuators is recognised by the
redundancymodules(viaparameterFO cable monitoring =On (not final device)).
Both display and the bus indicate Wrn FOC.The network is then operated as
an optical line and all actuators remain available.
●If one module fails (i.e.when the voltage supply is interrupted), only the actuator
connected to this module is disconnected from the loop, the remaining network
stays operative as a line. All other actuators remain available.
●The actuators have a redundant FO cable connection with a standard Profibus
DP interface (not redundant).
Cable routing and PLC fault evaluation
●To increase service safety, install cables for go-and-return in the loop on sepa-
rate lines.
●To achieve complete monitoring of the redundant optical loop, all FO fault signals
(including the fault output of the FO coupler) at the master must be evaluated
by the PLC controls.
Setting response and slot time
The following settings should performed at the master:
10
Network topologies

●The minimum response time of all slaves (min TSDR) has to be set to a value
of 11 bit times (basic setting) or more.In the event of continuous communication
faults, this value has to be verified.
●The Profibus slot time (TSL) must be set as to ensure that on request of the
master, the response of the slaves arrives at the master within the slot time -
even in the event of a fault in the fibre optic cable.The minimum slot time in bit
times depends on the data rate, the total length of the fibre optic cable and the
number of actuators used within the loop.
Calculation of slot time:
TSL ≥max_TSDR + LFO * tFO + nDL * tDL
TSL Slot time
max_TSDR Maximum response time of the slowest slave in bit times.In the table below, the
values of the AC 01.2 have been entered.
LFO Overall cable length of the FO cable used within the loop in km.
If bus segments start from the loop couplers, which have been extended beyond the
maximum electrical cable lengths using FO couplers or repeaters, the two longest
bus segments should be added to the FO cable length within the loop.
tFO Constant that accounts for the bit times per FO cable (refer to table)
nDL Number of actuators used within a loop
tDL Constant that accounts for the running time of an FO module in bit times (refer to
table)
