Moxa's ICF-1280I and ICF-1180I Profibus-to-fiber converters that transparently bridge Profibus to optical fiber while providing isolation and protection from interference (Pictured: ICF-1280I). Courtesy: Moxa Americas Inc.Moxa’s Profibus-to-fiber converters—the ICF-1280I and ICF-1180I—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 fiber or up to 25 miles on single-mode fiber at data rates up to 12 Mbps. An integrated Remote Fiber Diagnosis function eliminates the need for specialized test equipment and significantly shortens troubleshooting time in expansive installations by allowing one person to examine fiber connections for the overall topology from any individual converter.

The Moxa ICF-1280I has dual ports to build a redundant fiber 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 minimize 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 recognizes 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.

A Comprehensible Guide to Controller Area NetworkA Comprehensible Guide to Controller Area Network

A Comprehensible Guide to Controller Area Network by Wilfried Voss represents the most thoroughly researched and most complete work on CAN available in the marketplace. Controller Area Network (CAN) is a serial network technology that was originally designed for the automotive industry, especially for European cars, but has also become a popular bus in industrial automation as well as other applications. The CAN bus is primarily used in embedded systems, and as its name implies, is a network technology that provides fast communication among microcontrollers up to real-time requirements, eliminating the need for the much more expensive and complex technology of a Dual-Ported RAM. This book provides complete information on all CAN features and aspects combined with a high level of readability. Read more…
