Introduction
There are two variations of PROFIBUS protocol, PROFIBUS DP
(Decentralized Peripherals) and PROFIBUS PA (Process Automation).
PROFIBUS PA is used with applications for which the end device needs a
power supply from the PROFIBUS PA device and where an intrinsic safe
mechanism is also required. Due to the power supply criteria, the number
of attached devices is limited. PROFIBUS DP is used in production
automation and when centralized controllers are used to manage the
system. It supports up to 126 attached devices and is the most commonly
used PROFIBUS specification.
The ICF-1180I series PROFIBUS-to-fiber converters are based on
PROFIBUS DP. ICF-1180I products are used to convert PROFIBUS signals
from copper to optical fiber. ICF-1180I multi-mode models can be used to
extend PROFIBUS signal transmission up to 4 km and ICF-1180I
single-mode models can extend PROFIBUS signal transmission up to 45
km. ICF-1180I converters provide 2 kV isolation protection for the
PROFIBUS system and have dual power inputs to ensure uninterrupted
operation of the PROFIBUS device.
Why Convert PROFIBUS to Fiber?
Optical fiber communication not only extends the communication
distance, but also provides many advantageous features.
IMMUNITY FROM ELECTRICAL INTERFERENCE: Fiber is immune
from electromagnetic interference or radio frequency interference. It
provides a clean communication path and is immune to cross-talk.
INSULATION: Optical fiber is an insulator interface; the glass fiber
eliminates the need for using electric currents as the communication
medium.
SECURITY: Fiber cannot be tapped by conventional electronic means
and is very difficult to tap into optically while radio and satellite
communication signals can be captured easily for decoding.
RELIABILITY & MAINTENANCE: Fiber is immune from adverse
temperature and moisture conditions; hence, it does not corrode or lose
its signal, and is not affected by short circuits, power surges, or static
electricity.
Auto/Manual Baudrate Settings
The ICF-1180I series converts signals back and forth between PROFIBUS
and fiber and supports baudrates from 9.6 kbps to 12 Mbps. Engineers do
not need to know the baudrate of the connected PROFIBUS device since
the ICF-1180I can automatically detect the baudrate of the PROFIBUS
device and apply this baudrate directly. This is an extremely convenient
feature. If necessary, baudrates can be set to a fixed value via DIP
switches.

PROFIBUS Fail Safe
When the PROFIBUS device malfunctions or the serial interface fails, it
will generate electrical noise that can cause bus failure. Traditional media
converters will let the noise signal pass through the fiber and on to the
other converter, disrupting data communication between the two buses
and eventually causing communication to cease across the entire system.
When this occurs, engineers will not be able to easily locate the failed
device because the entire PROFIBUS network is down. To avoid this
situation, the ICF-1180I is designed to detect and recognize noise signals.
If the bus fails on one side, the noise signal will not propagate through the
ICF-1180I and affect additional bus segments. In addition, the ICF-1180I
will also trigger an alarm notification to the field engineer on the location
of the failure.
Fiber Link Monitor
The ICF-1180I series’ Fiber Link Monitor function detects communication
errors on either the fiber side or the PROFIBUS side. When a
communication error occurs, the corresponding LED will shine red and the
relay alarm will activate.
Reverse Power Protection
The Reverse Power Protection feature provides extra protection against
accidentally connecting the power cables to the wrong terminal. The
converter is designed to detect automatically which power wire is positive
and which is negative, and then adjust the power supply accordingly.
Remote Fiber Diagnosis
Fiber optic cables are often deployed for long distance communication
and a fiber optic inspection pen is used by engineers to detect
communication quality issues. ICF-1180I series converters eliminate the
need for a fiber optic inspection pen by providing a Fiber Test function
that uses DIP switch adjustments. By using the Fiber Test function, users
can determine which side (Tx or Rx) is causing the problem on the
converter. Fiber cable abnormalities can be automatically detected and
identified by the LED indicator.

Using Remote Fiber Diagnosis:
Set DIP switch SW8 to the ON position on any ICF-1180I converter and
then look at the Ready LED status. A flashing green Ready LED indicates
that the Fiber Test has finished. The P1 (Fiber port) LED indicates which
side (Tx or Rx) is causing the problem. If there are no fiber connection
errors in the entire topology, the related LEDs will shine green or remain
OFF. If the fiber connection error is adjacent to the converter, the status
will also be indicated by the P1 LEDs. A flashing red light on P1 means that
the Rx fiber cable connected to this port is broken. Similarly, a solid red
light on P1 means that the Tx fiber cable in this port is broken. Further
descriptions and troubleshooting can be found in the Troubleshooting
table.

ATTENTION
Electrostatic Discharge Warning!
To protect the product from damage due to electrostatic
discharge, we recommend wearing a grounding device when
handling your ICF-1180I.

Mounting
The aluminum DIN rail attachment plate should be fixed to the back panel
of the ICF-1180I when you take it out of the box. If you need to reattach
the DIN rail attachment plate to the ICF-1180I, make sure the stiff metal
spring is situated towards the top, as shown in the figures below.
STEP 1:
Insert the top of the DIN rail into
the slot just below the stiff metal
spring.
STEP 2:
The DIN
-rail attachment unit will
snap into place as shown below.
To remove the ICF-1180I series from the DIN rail, simply reverse Steps 1
and 2 above.
Wiring the Alarm Contact
The alarm contact is made up of the two middle contacts of the terminal
block on the ICF-1180I’s top panel. Refer to the next section for detailed
instructions on how to connect the wires to the terminal block connector,
and how to attach the terminal block connector to the terminal block
receptor.
In this section, we explain the meaning of the two contacts used to
connect the alarm contact.
FAULT: The two middle contacts of the 6-contact
terminal block connector are used to detect both
power faults and port faults. The two wires
attached to the Fault contacts form an open
circuit when:
1. The ICF-1180I has lost power from one of
the DC power inputs.
OR
2. One of the ports for which the
corresponding PORT ALARM Dip Switch is
set to ON is not properly connected.
If neither of these two conditions occurs, the
Fault circuit will be closed.

Wiring the Redundant Power Inputs
STEP 1: Insert the negative/positive DC wires
into the V
-/V+ terminals.
STEP 2:
To keep the DC
wires from pulling loose,
use a small flat
-
blade screwdriver to tighten the
wire
-clamp screws on the front of the terminal
block connector.
STEP 3:
Insert the plastic terminal block
connector prongs into the terminal block
receptor, which is located on the
ICF-1280I
’s top
panel.
ATTENTION
Before connecting the ICF
-1180I
to the DC power inputs, make
sure the DC power source voltage is stable.
You should also pay attention to the following:
•The temperature rating of the input connection cable should be higher
than 91°C.
•The cross sectional area of the ground wire should be at least 3.31
mm2.
•The terminal block plug should be suitable for 28-12 AWG
(0.0804-3.31 mm2) wire and a torque of 4.5 lb-in.

Slot Time Settings
When ICF-1180I converters are used as part of a PROFIBUS network,
frame delays can occur, with the time of the delays determined by the
total cable length and network topology. In this case, a sufficient “slot
time” should be configured to prevent the PROFIBUS master from timing
out. We recommend using the following formula to calculate the preferred
PROFIBUS master’s slot time.
For a point-to-point topology:
Slot time = A + B × L + 13 × N
