ICF-1280I Series Quick Installation Guide Moxa Industrial PROFIBUS-to-Fiber Converter Edition 5.0, February 2017 Technical Support Contact Information www.moxa.
Introduction The ICF-1280I series PROFIBUS-to-fiber converters are based on the PROFIBUS DP standard, and are compliant with EN 50170. The converters are mainly used to extend the transmission distance of PROFIBUS devices over optical fiber, and provide redundant transmission. More specifically the ICF-1280I series converts PROFIBUS signals between copper and fiber wires, and extends PROFIBUS transmission up to 4 km (for multi-mode models) or up to 45 km (for single-mode models).
halt. 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-1280I series converter has a mechanism to detect and recognize noise signals. If the bus fails on one side, the noise signal will not propagate through the ICF-1280I converter and affect additional bus segments. In addition, the ICF-1280I converter will also trigger an alarm to provide the location of the failure to the field engineer.
Using Remote Fiber Diagnosis: Set DIP switch SW8 to the ON position on any ICF-1280I converter and then note the status of the Ready LED. A flashing green Ready LED indicates that the Fiber Diagnosis has finished. The Fault LED indicates the location of the fiber connection abnormality. The P1 or P2 LED indicates which side (Tx or Rx) is causing the problem. The Fault LED will shine a steady red to indicate an adjacent fiber connection error, or flash red to indicate a non-adjacent fiber connection error.
• Remote Fiber Diagnosis • Auto baudrate detection and data speeds up to 12 Mbps • PROFIBUS bus fail safe • Alarm by relay output • Provides 2 kV galvanic isolation • Power polarity protection • Extend PROFIBUS transmission distance: Up to 45 km with single-mode (ICF-1280I-S models) Up to 4 km with multi-mode (ICF-1280I-M models) • Point-to-point, linear (bus), star, and redundant ring topologies • Dual power input for redundancy • Wide operating temperature from -40 to 75°C (for “
ICF-1280I Panel Layouts Top View Bottom View Front View ATTENTION Electrostatic Discharge Warning! To protect the product from damage due to electrostatic discharge, we recommend wearing a grounding device when handling your ICF-1280I series converters. Mounting The aluminum DIN rail attachment plate should be fixed to the back panel of the ICF-1280I converter when you take it out of the box.
STEP 1: STEP 2: Insert the top of the DIN rail into The DIN rail attachment unit will the slot just below the stiff metal snap into place as shown below. spring. To remove the ICF-1280I series converter from the DIN rail, simply reverse Steps 1 and 2 above. Wiring the Alarm Contact The alarm contact is made up of the left two contacts of the terminal block on the ICF-1280I’s top panel.
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. • • Fiber Cable ST-Port Pinouts ST-Port to ST-Port Cable Wiring PROFIBUS Pin Assignment PIN 1 2 3 4 5 6 7 8 9 Signal Name N.C.

5. Conditions of safe usage: • This equipment must be installed in an enclosure that can only be accessed with a key or other tool, and which provides a degree of protection not less than IP54 in accordance with IEC 60079-15. • These devices are designed for use in an area of not more than pollution degree 2 in accordance with IEC 60664-1. • Transient protection must be provided and set at a level not exceeding 140% of the peak rated voltage value at the supply terminals to the equipment.
DIP Switch Settings There are 8 DIP switches on the top panel of the ICF-1280I series converter. All DIP switches except SW5 are set to the factory default OFF position. Transmission Speed (kbps) Auto (default) 12000 6000 3000 1500 500 187.5 93.75 45.45 19.2 9.
LED Indicators There are 9 LED indicators on the front panel of the ICF-1280I. LED Color PWR1/PWR2 Solid green Off Ready Solid green P1 Level/ P2 Level Flashing green* Flashing red* Flashing red and green* Off Green Orange Red P1/P2 (Fiber) Flashing/ solid green Solid red* Description Relay Status Closed Open Power is on Power is off, or power error condition exists Baudrate is detected, converter is Closed ready for communication Fiber diagnosis is finished Closed Detecting baudrate.
Troubleshooting LED Indicators and Fiber Diagnosis LED Ready Status Flashing green Description Fiber diagnosis finished Status/Troubleshooting Check Fault LED; At least one converter is in Fiber Diagnosis mode; Check PROFIBUS master settings; Tx and Rx cables crossed Flashing Detecting No PROFIBUS node; red baudrate No PROFIBUS signal received; Tx and RX crossed over; Baudrate setting is incorrect.
ATTENTION This is a Class 1 laser/LED product. Do not stare into the laser beam. Fiber Signal Intensity Diagnosis In some circumstances you may need to measure the receive level of fiber optic channels P1 and P2 with a voltmeter, which can be connected while the device is operating (doing so will not affect data transmission).
When taking measurements, use a standard ungrounded, high-resistance voltmeter. The internal resistance of the measurement sockets is approximately 30 kΩ. • Multi-mode: ICF-1280I-M-ST • Single-mode: ICF-1280I-S-ST NOTE These charts are not suitable for use with a Remote Fiber Diagnosis test.
