Overview
PROFIBUS Fail Safe
The ICF-1180I series 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)
The ICF-1180I converters can be used to connect serial devices to a
fiber ring. To form the ring, connect the Tx port of one ICF-1180I to the
Rx port of a neighboring converter. Once the ring is set up, simply use
the DIP switches to configure the ICF-1180I converters for “single ring
mode.” When one node transmits a signal, the signal travels around
the ring until it returns back to the transmitting unit, which then blocks
the signal. With the ICF-1180I, you can set up fiber rings and connect
up to 126 nodes in a ring.
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.
Ring Operation
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, 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.
