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.
