IMMFP01 | ABB Bailey Multi-Function Processor Module

ABB Bailey IMMFP01 Multi-Function Processor Module

The ABB Bailey IMMFP01 is a Multi-Function Processor (MFP) module for the INFI 90 distributed control system (DCS). It serves as the primary controller executing control strategies, managing loop logic, and coordinating communications across the INFI 90 backplane. The IMMFP01 is widely deployed in legacy Bailey installations where deterministic control, stable operation, and long lifecycle support are critical.

Features & Benefits

1. Multi-Loop Control Execution: Handles regulatory and sequence control for diverse process units without overtaxing rack CPU resources.
2. Deterministic Scan Behavior: Stable cycle times improve repeatability for critical loops (steam, combustion, high-inertia drives).
3. INFI 90 Backplane Communications: Coordinates with I/O modules and peer controllers via Controlway, simplifying wiring architecture.
4. Redundancy-Ready: Supports paired or hot-standby configurations for high-availability applications.
5. Drop-In Replacement: Standard single-width form factor fits existing card guides and backplane connectors—no cabinet rework required.

Applications

• Power generation boiler and turbine control
• Petrochemical process control
• Water and wastewater treatment automation
• Pulp and paper mill DCS
• Cement and mining process control

FAQ

Q: Is the IMMFP01 compatible with Symphony and Harmony systems?
A: Yes. The IMMFP01 is backward compatible with ABB Symphony and Harmony systems, as well as legacy Bailey INFI 90 and INFI 90 Open Process Control Systems.

Q: How do I load control strategies into the IMMFP01?
A: Control strategies are loaded via the faceplate RS-232 maintenance port using ABB engineering software (e.g., Function Code Builder, Composer).

Q: Can I use IMMFP01 in a redundant configuration?
A: Yes. The IMMFP01 supports hot-standby redundancy when engineered with paired modules and appropriate redundancy termination units.

Installation Guide

1. Power down the INFI 90 rack or confirm hot-swap capability.
2. Insert IMMFP01 into the designated processor slot in the Module Mounting Unit (MMU).
3. Verify proper seating and retention latch engagement.
4. Connect RS-232 maintenance cable to the faceplate port for configuration.
5. Load control application via ABB engineering software.
6. Verify module status LEDs and backplane communication health.

Selection Tips

• System Compatibility: Confirm your INFI 90 rack revision supports IMMFP01 (most standard MMU racks do).
• Redundancy: For critical loops, order a second IMMFP01 and redundancy termination hardware.
• Software Version: Ensure your engineering software supports the IMMFP01 firmware revision.
