ABB INBIM02 Bus Interface Module

Overview

The ABB INBIM02 Bus Interface Module is a communication gateway designed for the ABB Bailey INFI 90 Distributed Control System. It links the high-speed plant network (Infi-Net) with the local module bus inside the controller cabinet, enabling coordinated data exchange between controllers, communication modules, and distributed I/O components.

Within the INFI 90 architecture, the BIM module acts as a key interface responsible for routing plant-wide control data to the appropriate module bus segments. The design ensures reliable message transmission, stable network performance, and synchronization across the distributed control infrastructure.

The INBIM02 module is typically installed in the INFI 90 rack backplane where it manages communication traffic between the controller subsystem and the system-wide network.

Technical Specifications

Key Functional Characteristics

The INBIM02 Bus Interface Module performs several critical roles within an INFI 90 system:

Provides the communication path between the Infi-Net plant network and the local module bus architecture.

Deterministic Data Transfer
Maintains stable and predictable communication between distributed controllers and I/O subsystems.

System Expansion Support
Allows multiple control racks and module buses to be integrated into the plant-wide control network.

Operational Diagnostics
Integrated LED indicators assist engineers with troubleshooting communication faults and monitoring system status.

Industrial Reliability
Designed for continuous process control environments such as energy production, chemical processing, and heavy manufacturing.

Typical Applications

Power generation plants where reliable communication between controllers and field instrumentation is required.

Oil and gas production facilities using distributed process control architectures.

Chemical and petrochemical plants requiring synchronized control networks.

Industrial manufacturing lines utilizing ABB INFI 90 control infrastructure.

FAQ

What role does the INBIM02 module play in the INFI 90 system?
The module functions as a communication gateway connecting the Infi-Net plant network to the local module bus, allowing controllers and I/O modules to exchange operational data.

Is the INBIM02 interchangeable with earlier BIM versions?
In many INFI 90 installations, the INBIM02 replaces earlier Bus Interface Modules while maintaining compatibility with the existing control architecture. System configuration should always be verified before replacement.

Does the module require an external power supply?
No. Power is delivered through the INFI 90 rack backplane, typically at 24 VDC.
