Description
Product Overview
Foxboro FBM222 is a Redundant PROFIBUS Communication Module designed for the Foxboro I/A Series® and Foxboro Evo™ Distributed Control System (DCS) platforms. It provides a high-capacity communication interface between the Foxboro control system and PROFIBUS-DP/PA field devices, including motor drives, remote I/O modules, intelligent field instruments, and other PROFIBUS-compatible equipment.
The Foxboro FBM222 enables integration of PROFIBUS networks into the DCS architecture through Distributed Control Interface (DCI) blocks. It supports single or redundant configurations and provides two PROFIBUS communication ports, allowing connection to multiple field devices while maintaining high system availability.
Foxboro FBM222 is widely used in process industries such as oil & gas, chemical, power generation, and manufacturing plants where reliable fieldbus communication is required. Its redundant communication capability, hot-swappable design, and support for PROFIBUS-DP/PA devices make it suitable for mission-critical automation applications.

FBM222
Main Features and Advantages
Foxboro FBM222 provides a reliable bridge between PROFIBUS field devices and the Foxboro DCS environment. It allows users to connect intelligent field equipment without replacing existing PROFIBUS-based infrastructure.
A key advantage of Foxboro FBM222 is its redundant communication capability. The module can operate in redundant configurations with redundant termination assemblies and communication paths, improving availability for critical process applications where interruption of field communication could affect production or safety.
The dual PROFIBUS channel architecture of Foxboro FBM222 allows connection of multiple PROFIBUS networks. Each port can support a large number of slave devices, reducing the need for additional communication hardware and simplifying system architecture.
Foxboro FBM222 supports PROFIBUS-DP and PROFIBUS-PA devices, allowing integration of a wide range of field equipment, including:
- Variable frequency drives (VFDs)
- Motor control centers
- Remote I/O systems
- Intelligent transmitters
- Field instrumentation
- PROFIBUS-compatible analyzers
The module provides advanced diagnostic functions that improve maintenance efficiency. Operators can monitor communication health, device status, and network conditions through the Foxboro control system, reducing troubleshooting time and improving plant reliability.
Foxboro FBM222 supports online maintenance features, including hot replacement capability in suitable redundant configurations. This allows maintenance activities to be performed with minimal disruption to ongoing plant operations.
The compact modular design of Foxboro FBM222 allows efficient installation in Foxboro I/O cabinets. It is suitable for both new automation projects and modernization of existing Foxboro I/A Series systems.
Applications
Foxboro FBM222 is primarily used in industrial automation systems requiring integration of PROFIBUS field devices into a centralized DCS platform.
In oil and gas facilities, Foxboro FBM222 is used to connect PROFIBUS-based motor drives, remote I/O stations, and intelligent instruments for monitoring and control of production equipment.
In chemical and petrochemical plants, the module supports communication with distributed field devices while maintaining reliable data exchange between the process control system and plant equipment.
In power generation facilities, Foxboro FBM222 can be used for integrating auxiliary equipment such as motor control systems, electrical devices, and intelligent field instrumentation into the Foxboro DCS.
Manufacturing and water treatment facilities also use the FBM222 for reliable PROFIBUS network integration where continuous operation and diagnostic visibility are important.
Typical application areas include:
- Oil & gas processing plants
- Petrochemical facilities
- Chemical production systems
- Power generation plants
- Water and wastewater treatment
- Industrial manufacturing
- Motor drive integration
- Remote I/O communication
- Foxboro DCS modernization projects
