Introduction
The ICF-1180I 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 provides 2 kV isolation
protection for the PROFIBUS system and dual power inputs to ensure that your PROFIBUS device will perform uninterrupted.
Fiber Cable Test Function
Fiber-optic cables are usually deployed for long-distance communication. To ensure proper communication across the fiber-optic cables,
engineers use fiber sensors. A fiber cable test function through DIP switch adjustments helps ICF-11801 converters eliminate the need to rely on
fiber-optic sensors.
This function not only detects fiber communication abnormalities but also validates the format of the received packet. It can also determine which
side (Tx or Rx) is causing the problem.
PROFIBUS Fail-Safe
When the PROFIBUS device malfunctions or the serial interface fails,
it will generate electrical noise, resulting in bus failure. Traditional
media converters will let the noise signal pass through the fiber and
on to the other converter. This will disrupt data transmissions
between the two buses and eventually communication ceases across
the entire system. When this occurs, the engineer will not be able to
easily locate the failed device because the entire PROFIBUS network
is down. To avoid this situation, the ICF-1180I was 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.
Auto/Manual Baudrate Settings
The ICF-1180I Series simply converts the signal back and forth between PROFIBUS and fiber. The ICF-1180I Series works under baudrates
between 9.6 kbps to 12 Mbps. Engineers do not need to know the baudrate of the connected PROFIBUS device.
The ICF-1180I Series 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.
Fiber Inverse Function
The ICF-1180I provides a fiber inverse function to choose fiber-optic light ON or light OFF when sending logic signal ‘1’. For default settings, fiber-
optic is light OFF when sending logic signal ‘1’; in Fiber Inverse mode, fiber-optic is light ON when sending logic signal ‘1’.
