ABB P-HC-BRC30000000 – The Central CPU Module for ABB Symphony Plus Harmony Rack Systems

The ABB P-HC-BRC30000000, widely known as the BRC300 (Bridge Controller 300) , is a high-performance central CPU module designed for ABB Symphony Plus Harmony Rack (HR Series) and Bailey INFI 90 distributed control systems (DCS). As the primary processing engine in ABB Bailey and INFI 90 control environments, this module serves as the core computational unit of the process control station (FCS) while simultaneously providing bridging and routing functionality between field control stations and the upper-layer INFI-NET network.

Key Features & Technical Specifications

Functional Role & System Architecture

The P-HC-BRC30000000 module performs two critical functions within the DCS architecture:

1. Control Processing – Executes control logic, collects I/O data, performs PID calculations, and manages sequence of events (SOE) recording with ≤2ms resolution.
2. Bridge/Routing – Transmits field data to the INFI-NET backbone while receiving and distributing upper-layer commands to field devices.

This dual identity as both a controller and a network bridge distinguishes the BRC300 from standard controllers. It intelligently routes data to the appropriate bus, ensuring seamless communication across all control layers.

High-Speed Processing & Memory Architecture

The module features a 32-bit ColdFire MCF5407 RISC processor running at 160 MHz with 257 MIPS computational performance. It supports over 150 predefined ABB function codes, as well as C applications, Batch 90, and user-defined functions. The memory architecture includes:

• 8MB SDRAM – For real-time control data and application execution
• 512KB NVRAM – For critical variable retention
• 2MB Flash ROM – For firmware and configuration storage

This robust memory structure ensures rapid read/write operations across configuration databases, system files, and real-time control data, with built-in integrity checking to prevent data corruption during high-load cycles.

Communication & Network Integration

The BRC300 integrates seamlessly with ABB's communication frameworks, supporting:

• INFI-NET – Plant-wide system buses for controller-to-controller messaging
• Ethernet – For high-speed network integration
• Modbus & PROFIBUS DP – For connectivity with third-party devices and systems
• RS-232 & RS-485 – For serial communication with legacy equipment

Continuous message arbitration and network anomaly correction ensure synchronized data exchange across all control units, maintaining system stability even during peak demand.

Programming & Configuration Flexibility

The BRC300 supports multiple programming languages and methodologies:

• Function Code Programming – For engineers familiar with traditional Bailey logic
• Ladder Logic – For PLC-style control implementation
• C Language – For complex algorithm development
• Basic – For simpler automation tasks
• Batch 90 – For batch process applications

This flexibility allows engineering teams to leverage existing expertise while enabling advanced custom control strategies.
