Abb IMFP03 Bailey Processor module

Abb IMFP03 Bailey

It is a key component in ABB’s INFI 90 distributed control system (DCS).

Comprehensive Product Description

First and foremost, it is crucial to understand that the ABB IMFP03 is not a single product, but a product series or a module model. It is a key component of the INFI 90 Distributed Control System (DCS), originally from Bailey, which was acquired by ABB.

In simple terms, the IMFP03 is a Multi-Function Processor module, which can be thought of as the brain of a control “station” or “node” within the DCS.

1. Core Identity and System Affiliation

• Product Name: ABB Bailey IMFP03 Multi-Function Processor Module

• System Affiliation: ABB Bailey INFI 90 Distributed Control System (DCS)

• Role: Serves as the core processor for a Process Control Unit (PCU) or a subgroup controller within the INFI 90 network.

2. Primary Functions

The IMFP03 module is a powerful controller responsible for executing complex control logic and data processing. Its main functions include:

• Control Execution: Runs user-programmed control strategies, such as PID regulation, sequential control, logic operations (AND, OR, NOT), mathematical calculations, and advanced algorithms.

• Data Acquisition: Collects process data (e.g., temperature, pressure, flow) from field devices (e.g., sensors, transmitters, actuators) through matching I/O sub-modules.

• Communication Hub: Acts as a critical node in the control network, facilitating high-speed data exchange with other PCUs, Operator Workstations (OWS), and Engineering Workstations (EWS) via the INFI-NET network.

• Redundancy Support: To ensure high availability and system reliability, the IMFP03 can typically be configured for redundant (hot standby) operation. A primary module runs while a backup module synchronizes data in real-time. If the primary module fails, the backup seamlessly takes over control, preventing production process interruptions.

3. Physical and Performance Characteristics

• Modular Design: Features a standard card-based design for insertion into dedicated INFI 90 system racks or slots.

• Powerful Processing Capability: For its era (the 1980s-90s), it possessed robust processing power, capable of handling thousands of I/O points and complex control loops.

• Memory: The module contains its own memory for storing the operating system, control configuration (program), and real-time data.

• LED Status Indicators: The module faceplate typically has multiple LED indicators displaying operational status (e.g., Normal, Fault, Primary/Backup status, Network Communication status), facilitating field maintenance and troubleshooting.

4. Typical Applications

The ABB Bailey INFI 90 system and its IMFP03 processor were widely used in heavy industries demanding high reliability and control performance, such as:

• Thermal Power Plants

• Nuclear Power Plants

• Chemical Plants

• Oil and Gas Pipelines

• Water Treatment Plants

• Metallurgical Industry

In these applications, the IMFP03 is responsible for controlling critical equipment like boilers, turbines, reactors, and compressor trains.
