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.

- 3 -

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.

- 4 -

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.

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
