Moxa unveils its latest PROFIBUS-to-fibre converters featuring a Bus Fail Safe that detects noise signals

Published on 19 December, 2013

Driving innovation and extending its leadership in industrial networking technology, Moxa has introduced two new PROFIBUS-to-fibre converters that transparently bridge PROFIBUS to optical fiber, providing total isolation, protection against EMI/RFI interference, and freedom from equipment grounding problems.

Equally important, the two new converters help extend connections up to 2.5 miles on multi-mode fibre or up to 25 miles on single-mode fibre at data rates up to 12 Mbps -- well beyond the speed and distance limitations of traditional twisted pair copper installations. An integrated Remote Fibre Diagnosis function eliminates the need for specialized test equipment and significantly shortens troubleshooting time in expansive installations by allowing one person to examine fibre connections for the overall topology from any individual converter.

The Moxa ICF-1280I has dual ports to build a redundant fibre ring with zero recovery time, while the Moxa ICF-1180I is a single port converter. Both models feature 2 KV isolation protection and dual power inputs to ensure that PROFIBUS devices perform uninterrupted. To avoid configuration errors and minimise manual configuration efforts of baudrate settings, both also incorporate auto baudrate detection. This feature enables fast, error-free configuration of the converters and significantly reduces system deployment time.

To prevent a single bus failure from affecting the entire PROFIBUS network, the converters feature a Bus Fail Safe that detects and recognises noise signals. If the bus fails on one side, the noise signal will not propagate through the converter and affect additional bus segments. Also, the converter will automatically trigger an alarm notification to the field engineer on the location of the failure, allowing them to quickly locate the failed device.
