Description

The Foxboro FCM100ET (P0926GS) is a high-performance Fieldbus Communications Module designed for the Foxboro I/A Series and Foxboro Evo distributed control systems. It serves as a critical interface bridge between the high-speed Ethernet mesh network and the 2 Mbps HDLC module fieldbus. Engineered for demanding industrial environments such as oil refining, chemical processing, and power generation, the FCM100ET enables seamless data integration for DIN rail-mounted Fieldbus Modules (FBMs). By providing high-speed, reliable diagnostic and process data throughput, this module ensures optimal control loop performance and minimizes system latency.

Features

• Supports 100 Mbps Ethernet connectivity via fiber optic or copper interfaces.
• Facilitates redundant network topologies to eliminate single points of failure.
• Handles internal protocol translation and data buffering to isolate local fieldbus traffic.
• Integrated station management system for continuous self-diagnostics and FBM health monitoring.
• Hot-swappable design for maintenance without powering down the baseplate.
• Supports up to 32 FBMs per fieldbus segment.

Applications

The FCM100ET is widely utilized in mission-critical process automation, including oil and gas refining, petrochemical plants, and power generation facilities, where reliable communication between control processors and field I/O is essential for operational continuity.

Technical Specifications

Installation Guidelines
