IMMPI01 | ABB Bailey Multifunction Processor Interface

ABB Bailey IMMPI01 Multi-function Processor Interface Module

IMMPI01 is a multi-function processor interface module in ABB Bailey industrial automation system, mainly used to connect different types of processors, controllers or communication buses to achieve data interaction, protocol conversion and function expansion between systems. The following is a detailed introduction to its core functions, technical characteristics and application scenarios:

Functions and Features

Multi-protocol communication hub

Supports a variety of industrial communication protocols, such as:

Modbus RTU/ASCII (serial communication)

Ethernet/IP, PROFINET, Modbus TCP (Ethernet communication)

Specialized protocols (such as ABB Bailey INFI 90 system bus protocol)

Can be used as a protocol converter to achieve transparent data transmission between different buses (such as serial ports and Ethernet) and solve the compatibility issues of heterogeneous systems.

Flexible processor adaptation

Adapts to ABB Bailey series processors (such as IMMPU series main processors) and supports connection with third-party controllers (such as PLC, DCS) or intelligent devices (such as inverters, instruments).

Supports multi-host communication architecture and can exchange data with multiple processors or host computers at the same time.

Data processing and logic functions

Built-in microprocessor supports simple data processing, filtering, arithmetic operations (such as summation, average calculation) and logic control (such as conditional triggering, event alarm).

Configurable data mapping table to flexibly define the address, type and transmission rules of input/output data.

High reliability design

Electrical isolation: The communication interface is isolated from the system (usually ≥1500V AC), anti-electromagnetic interference (EMI) and surge shock, suitable for industrial environments.

Redundancy support: Some models support dual power input or communication link redundancy to improve system availability.

Modularity and easy maintenance

Adopting compact modular design, it can be directly inserted into the backplane bus of the control cabinet (such as INFI 90 system rack) and supports hot swapping (system support required).

Equipped with status indicators (power, communication, fault) to facilitate real-time monitoring of module operation status.
