ICF-1180I/1280I Series Serial Media Converters > Serial Media Converters 14-32 www. m oxa. com 14 ICF-1180I/1280I Series Industrial PROFIBUS-to-fiber converters with redundant fiber ring Overview The ICF-1180I/1280I series industrial PROFIBUS-to-fiber converters are used to convert PROFIBUS signals from copper to optical fiber. The converters are used to extend serial transmission up to 4 km (multi- mode fiber) or up to 45 km (single-mode fiber). The ICF-1180I/1280I provides 2 kV isolation protection for the PROFIBUS system and dual-power inputs to ensure that your PROFIBUS device will perform uninterrupted. Optical-fiber cables are often deployed for long distance communication, and a fiber optic inspection pen is used by engineers to ensure proper communication quality of the fiber cable. The ICF-1180I/1280I series converters eliminate the need for a fiber-optic inspection pen by providing a Remote Fiber Diagnosis function that uses DIP switch adjustments. There are two major functions provided by Remote Fiber Diagnosis: (1) determining which side (Tx or Rx) is causing the problem on the converter; (2) examining the fiber connections for the overall topology from any individual converter. Fiber cable abnormalities can be automatically detected and identified by the LED indicator even if it is not adjacent to the converter. Remote Fiber Diagnosis facilitates fiber cable deployment and management, and also significantly shortens troubleshooting time by examining fiber connections for the overall topology from any individual converter. Remote Fiber Diagnosis Redundant Ring The ICF-1280I series converters can connect PROFIBUS devices in a redundant fiber ring topology. Use the DIP switch to configure all the ICF- 1280I converters to Redundant Ring mode. When a PROFIBUS master transmits a signal from one converter to the PROFIBUS slave devices, this signal will travel to all the converters around the ring until it returns to the original converter and terminate. The redundant ring structure ensures no packet loss with zero recovery time. › ›Redundant fiber ring with zero recovery time › ›Examine network-wide fiber communication from a single converter › ›Auto baudrate detection and data speed up to 12 Mbps › ›PROFIBUS Bus Fail prevents corrupted datagram in functioning segment › ›Alarm by relay output › ›2 kV galvanic isolation protection › ›Dual-power inputs for redundancy › ›Extends PROFIBUS transmission distance up to 45 km › ›Wide temperature range model available for -40 to 75°C environments › ›Supports Fiber Signal Intensity Diagnosis › ›Fiber inverse feature (ICF-1180I) › ›Fiber cable test function validates fiber communication
