Description

Overview

The ABB IMCIS12 is a communication interface module designed for use within ABB Bailey INFI-90 and NET90 distributed control systems. It operates as a slave node on the control network, enabling structured data exchange between the main controller and remote I/O assemblies.

This module is typically deployed in systems that utilize distributed I/O layouts, where field signals are collected and processed across multiple remote racks. It ensures consistent communication timing, reliable data transfer, and system-level coordination.

Functional Characteristics

• Handles bidirectional data transfer between controller and remote I/O stations

• Executes INFI-90 communication protocol management at the module level

• Buffers process data to maintain deterministic update cycles

• Provides diagnostic feedback for communication and module status

• Supports expansion of distributed I/O networks across plant areas
