Product Description

The FBM232 is a high-performance Field Device System Integrator (FDSI) from Foxboro (Schneider Electric), providing a seamless Ethernet gateway for the I/A Series and Foxboro Evo systems.

This module allows the DCS to communicate with up to 64 third-party Ethernet field devices. Its downloadable software driver architecture supports a wide range of protocols, most notably Modbus TCP/IP, enabling high-speed data exchange with PLCs, motor control centers, and smart power meters.

Engineered for scalability and high-density integration, the FBM232 supports up to 2,000 Distributed Control Interface (DCI) block connections. Its rugged, field-mounted design features 10/100 Mbps auto-sensing and full hardware redundancy, ensuring that critical process data remains available even during network or hardware failures.

Technical Specifications

Application Scenarios

The FBM232 is ideal for modern plant communications, including:

• Substation Automation: Integrating smart protective relays and power meters via Ethernet.

• Large-Scale PLC Integration: Connecting multiple Allen-Bradley or Schneider Electric PLCs to a centralized Foxboro system.

• VFD Clusters: Managing and diagnosing large groups of Variable Frequency Drives over a single network.

• Remote I/O Bridging: Collecting high-speed data from remote Ethernet-based I/O manifolds.

Frequently Asked Questions

Q: How are protocols loaded onto the FBM232?
A: The FBM232 uses a downloadable driver. Required protocols are selected from the Foxboro driver library and loaded via the system configurator, allowing the same hardware to be repurposed for different communication tasks.

Q: Does this module support redundant network topologies?
A: Yes. When installed on a redundant baseplate, a pair of FBM232 modules provides full communication redundancy. If the primary module or cable fails, the secondary module immediately takes over all 64 device connections and 2,000 DCI blocks without interrupting the process.
