  • I/O Capacity: Supports up to 32 200-series FBM natively; expandable to 128 FBM with FEM100; overall I/O points up to 256 via remote I/O links

Functional Features:

  • Redundant, fault-tolerant operation with automatic switchover
  • Real-time data acquisition, alarm detection, and notification
  • Supports regulatory, sequential, and logic control strategies
  • Self-hosting mode enables startup and operation without host workstation
  • Bit-matching data consistency checks between redundant modules
  • Integration with Foxboro InTouch/Wonderware System Platform and Evo software stack

Application Scenarios:

  • Distributed control for process units in refining, petrochemicals, power generation
  • Critical loops requiring high availability and redundancy
  • Skid-mounted or remote I/O subsystems close to the process
  • Modernization projects requiring seamless integration with existing I/A Series infrastructure

Performance Parameters:

  • High-speed deterministic execution of control strategies
  • Low-latency communication over Ethernet to supervisory systems
  • Scalable I/O capacity with support for remote I/O expansion

Material and Structural Characteristics:

  • Rugged, sealed enclosure designed for unventilated cabinets
  • DIN-rail or panel-mountable within control cabinets
  • Industrial-grade components conformally coated for resistance to humidity and contaminants

Working Principle: The module executes control strategies (PID, logic, sequences) in real time, gathering data from FBM I/O modules via the fieldbus and sending setpoints. In redundant configurations, two modules run in parallel, exchanging information and performing bit-matching to ensure consistency. If a fault is detected in one module, the other takes over without disturbing the process. Installation Requirements:

  • Mount in a suitable control cabinet with proper grounding and bonding
  • Connect redundant power supplies and network links (Ethernet)
  • Terminate fieldbus connections to FBM/FEM baseboards per system diagrams
  • Configure IP addresses, redundancy settings, and control strategies using Foxboro engineering tools

Usage Notes:

  • Ensure cooling and airflow meet environmental class requirements
  • Perform periodic diagnostics checks and monitor health indicators
  • Before hot-swapping redundant modules, verify redundancy status and follow manufacturer procedures
  • Keep firmware updated to maintain security and feature compatibility
