The ICF-1180I 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 (multimode 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 fiberoptic
cables, engineers use fiber sensors. With fiber cable test function
through DIP switch adjustments, the ICF-1180I series 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 convert the signal back and forth between
PROFIBUS and fiber. The ICF-1180I series work 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.
