ABB IMMFP01 Multifunction Processor Board

Brand Overview

• Brand: ABB / Bailey Controls

• About the Brand: Bailey Controls was an industry pioneer in large-scale power plant and process automation before its integration into ABB. The legacy INFI 90 and Symphony architectures are widely recognized globally for delivering exceptionally reliable, deterministic distributed control system (DCS) architectures capable of executing complex process strategies under harsh conditions.

IMMFP03 ABB IMMFP03 Bailey Brand

Product Identification

• Model Number: IMMFP01

• Product Type: Multi-Function Processor (MFP) Board / Core Controller Card

• Product Family: INFI 90 / Symphony Distributed Control System (DCS) Series

Technical Specifications

• Core Functionality: Functions as the primary processing module within an INFI 90 system cabinet. It is engineered to independently execute complex control algorithms, continuous analog control loops, sequential logic networks, and localized data acquisition tasks.

• Processor Architecture: Driven by an onboard industrial-grade microprocessor optimized for real-time multitasking and deterministic control loop execution.

• Memory Management: Equipped with non-volatile memory (NVRAM) and RAM configurations to ensure that application programs, control block configurations, and runtime database variables are preserved during unexpected station power dropouts.

• Power Requirements: Designed to operate directly off the cabinet backplane, drawing a standard operating logic voltage of +5 VDC from the system power supply rails.

• Communication Routing: * Integrates a dedicated parallel module bus interface to seamlessly scan and control local analog and digital I/O modules.

  • Features serial communication links to connect with engineering workstations, terminal displays, or specialized interface cards (such as the IMMPI01).

• Diagnostics & Safety: Features an integrated hardware watchdog timer alongside background memory-checking routines. It can trigger instant fail-safe relay responses or facilitate automatic hot-swapping to a redundant secondary processor board if a critical hardware error is detected.

• Status Indicators: Outfitted with front-panel LED diagnostic displays that provide real-time operational status, error codes, and processor mode indications directly to maintenance personnel.

Target Industries

The IMMFP01 processor board is deployed in critical heavy continuous-process sectors where uninterrupted control is required:

• Power Generation & Utilities: Found inside central control racks for coal, gas, nuclear, and hydro generation systems to run boiler controls, coordinated burner sequences, and turbine systems.

• Pulp & Paper Processing: Deployed in mills to regulate continuous chemical digesters, recovery boilers, and automated paper reel tension systems.

• Oil, Gas & Petrochemicals: Integrated into refining plants, fractional distillation rows, and large terminal pipeline networks.

• Chemical Production Facilities: Applied inside complex chemical synthesis reactors, batch processing blenders, and storage distribution networks.

• Mining & Metal Smelting: Integrated into bulk material handling plants, large blast furnace blowers, and primary crushing systems.
