Bailey IMMFP02 Multi-Function Processor

The IMMFP02 Multi-Function Processor Module is ABB Bailey Infi-90's dedicated processing unit, designed to sit in the Infi-90 backplane and coordinate control logic, I/O, and communications for the system. It employs a 16 MHz microprocessor that drives module operation, with ROM containing the operating system instructions and function code library, plus RAM for runtime data and NVRAM for non-volatile storage. The microprocessor also constantly triggers the machine fault timer (MFT) circuit to detect and respond to failures. The module provides a DMA section, an I/O expander, and a data bus interface, along with a redundancy link and DCS link pathways to support reliable operation in industrial environments. Typical power requirements are 5 V DC with about 10 W of consumption and a 2 A supply rating, making it compatible with standard Infi-90 power rails. The IMMFP02 is used as the central processor within the Bailey Infi-90 control system, handling program execution, data handling, and communication with other modules and field I/O as described in its functional block diagrams. Catalog entries and distributor listings consistently identify the device as the IMMFP02 Multi-Function Processor Module for the ABB Bailey Infi-90 line, underscoring its role as a high-level processor module within the ABB Bailey family.
