ABB IMMFC03 Bailey Infi 90 Multifunction Controller

Description

The ABB IMMFC03 is a powerful Multi-Function Controller Module within the Bailey Infi 90 controller family. This module executes user-designed analog, digital, batch, and advanced control strategies, managing up to 64 I/O slave modules (including mixing high and low power slaves with a maximum of 20 high power slaves). It is capable of running 4,000 lines of BASIC or 5,000 lines of C programs, allowing function blocks and language programs to run concurrently. The ABB IMMFC03 serves as a direct functional replacement for the Network 90 NMFC03.

The hardware architecture consists of two printed circuit boards connected by a ribbon cable—the Central Processing Unit (CPU) board and the Memory (MEM) board—which attach to a single faceplate. Designed to reside in the INFI 90 Module Mounting Unit (MMU), it occupies two slots and communicates over the module bus and the slave expander bus.

Features

• Redundant Configuration Support: Provides hot standby redundancy when paired with an identically configured backup module running the same firmware revision level, achieving bumpless transfer of control during failover.
• On-Line Configuration Capabilities: Enables users to make configuration modifications (including changes to BASIC and C programs) on the backup controller without affecting the primary module or interrupting active process control logic.
• Diverse Programming Environment: Concurrently runs custom control strategies via standard Bailey function codes, BASIC, and C language programs.
• Comprehensive Security Framework: Features hardware error detection and correction (EDAC) for dynamic RAM, illegal address decoding, an independent Machine Fault Timer (MFT), and hardware-enforced memory management to lock C programs into defined sections of RAM.
• Advanced Process Quality Tagging: Monitors local and remote I/O signals for out-of-range or failure states, automatically tagging compromised data points as "bad quality" to preserve process predictability.

Applications

• Analog, digital, and advanced regulatory process loop control
• Batch process control and industrial sequencing
• High-level data handling using C and BASIC language programming
• Redundant DCS process automation configurations

Installation Guidelines

• Static Protection: Always use a grounding wrist strap and static dissipative work surface when handling the module to prevent electrostatic discharge (ESD) damage.
• Hardware Hardware Address & Options Configuration: Configure dipswitches U72 (Options), U73 (Baud Rate), and U75 (Module Address) on the CPU board prior to inserting the module into the rack.
• Power Shock Hazard Mitigation: Disconnect all power before installing dipshunts for slave modules on the MMU backplane (slave expander bus) to avoid severe or fatal shock.
• Cable Interface Routing: Connect the interface cable from the NTMF01 Termination Unit or NIMF01 Termination Module directly to the P3 card edge connector of the CPU board. Do not connect this to the MEM board.
• Physical Insertion: Slide the dual-board assembly smoothly into the assigned MMU slot position until the rear edge connectors are firmly seated in the backplane. Secure by turning the faceplate's two captive screws one-half turn until the screw notches are oriented vertically.
• Maintenance & Dust Removal: Clean and tighten all power and grounding connections every 6 months or during scheduled plant shutdowns. Use a static-safe vacuum cleaner to clear dust accumulation from modules, the MMU, the fan assembly, and the power entry panel.

Compliance and Certifications

• CSA: Certified for use as process control equipment in ordinary (nonhazardous) locations.
