3BUA000037R1 ABB CI862 Communication Module Master

Product Overview

The ABB CI862 (Article Number: 3BUA000037R1) is a high-performance communication interface module designed for the AC 800M controller series. This module specifically enables the integration of TRIO and Genius I/O systems into the modern 800xA control environment. By acting as a specialized master on the CEX-Bus, the CI862 provides a reliable migration path for legacy installations, allowing users to leverage advanced controller features while maintaining their existing field I/O infrastructure.

Technical Configuration

TRIO/Genius I/O Communication

The CI862 3BUA000037R1 is engineered to operate exclusively in Master mode. It manages the cyclic data exchange between the AC 800M processor and Genius I/O blocks or TRIO racks. This interface ensures high-speed synchronization and robust data integrity, making it a critical component for plants that rely on TRIO bus technology for remote field distribution.

CEX-Bus Scalability

As a CEX-Bus module, the CI862 mounts directly to the side of the AC 800M controller or on a CEX-Bus expansion unit. Its compact design allows for multiple communication interfaces to be housed in a single rack, providing the flexibility needed to handle complex, multi-protocol industrial networks without expanding the cabinet footprint significantly.

Reliability and Lifecycle Status

Currently designated with a "Classic" lifecycle status, the 3BUA000037R1 remains a vital spare part and expansion module for established industrial sites. It is built to withstand demanding storage and operating conditions, featuring a wide storage temperature range and high tolerance for non-condensing humidity, ensuring long-term hardware availability for critical infrastructure.

Technical Specifications

Installation & Maintenance Guide

Module Mounting

The CI862 3BUA000037R1 should be installed on the CEX-Bus with the controller powered down unless the specific baseplate supports hot-swap procedures. Proper grounding of the CEX-Bus and the TRIO network cable shield is essential to prevent electromagnetic interference from affecting signal quality.

Network Configuration

Configuration of the Genius/TRIO network is performed through the ABB Engineering Suite. Engineers must define the baud rate and device addresses within the control software to match the physical hardware settings of the field I/O blocks to ensure successful communication established by the master module.

Engineering Advantages

Seamless Legacy Integration

The primary advantage of the CI862 is its ability to bridge the gap between legacy TRIO I/O hardware and the contemporary AC 800M control logic. This eliminates the need for full system "rip-and-replace" upgrades, allowing for incremental modernization that minimizes downtime and capital expenditure.

Standardized Compliance

Adhering to CE marking and the WEEE Directive 2012/19/EU, the module meets stringent European safety and environmental standards. This compliance ensures that the hardware is suitable for global deployment in regulated industries, including power generation, water treatment, and chemical processing.

Technical FAQs

Q1: Can the CI862 be used as a Slave device?

A1: No, the 3BUA000037R1 is designed to operate strictly in Master mode to control the TRIO/Genius I/O bus.

Q2: What is the significance of the "Classic" lifecycle status?

A2: "Classic" status means the product is no longer in active volume production but is fully supported with spare parts, maintenance, and technical assistance by ABB.

Q3: Is there a specific mounting orientation required?

A3: The module should be mounted vertically on a standard DIN rail via the AC 800M CEX-Bus base to ensure optimal heat dissipation and secure electrical connection.
