IMMFP03 | ABB | Multifunction Processor Module

Description

The ABB IMMFP03 (Multifunction Processor Module) is a core controller for the Bailey Infi 90 and Symphony Plus distributed control systems. It is a powerful 32-bit standalone controller designed to execute complex control strategies, including continuous, sequential, and batch control logic. 

Specifications

• Part Number: IMMFP03 (Alternate: P-IMMFP-03, YIMMFP03)
  
• Microprocessor: 32-bit RISC processor operating at 32 MHz.
  
• Memory Architecture:
• NVRAM: 128 kbytes (for configuration and runtime data).
• RAM: 512 kbytes (32-bit data path for high-speed execution).
• ROM: 512 kbytes (Firmware storage).
• Power Requirements: +5 VDC at 2.0 A (10.0 W typical).
  
• I/O Capacity: Supports up to 64 slave modules via the Expand Bus.
• Operating Temperature: 0°C to +70°C (32°F to 158°F).
• Dimensions: 3.56 cm W x 17.78 cm H x 29.85 cm L.
• Weight: 0.84 kg (1.85 lbs) / Shipping Weight: 2 kg.

Features

• Advanced Logic Execution: Supports Function Block programming (CLD), allowing for sophisticated PID control, arithmetic operations, and boolean logic.
• High-Speed Bus Interface: Utilizes a 32-bit data path to ensure rapid communication between the processor and its onboard memory, minimizing scan times.
  
• Redundancy Support: Can be configured in a redundant pair (using an IMRPI01 module) for mission-critical applications, providing "bumpless" transfer if the primary module fails.
• Expander Bus Master: Manages all data traffic for attached Slave I/O modules (such as the IMCIS01 or IMASI03), coordinating the input/output refreshes for the entire rack.
• Backward Compatibility: Designed to seamlessly integrate into older Net 90 systems while remaining the standard for many Symphony Harmony installations.
• Front Panel Diagnostics: Equipped with an 8-segment LED display and status indicators to provide real-time error codes and module health information.
