ABB CI854AK01 3BSE030220R1 PROFIBUS-DP/V1 Interface Strengthens Legacy System Connectivity in Global Industrial Automation

Dec 31, 2025

ABB Supports Ongoing Industrial Operations
ABB, a global leader in electrification and automation technologies, continues to support industrial users operating legacy control systems through the CI854AK01 3BSE030220R1 PROFIBUS-DP/V1 Interface.
Originally introduced as part of ABB’s AC 800M communication portfolio, the CI854AK01 remains actively supplied as a spare part for systems placed on the market before July 22, 2017, ensuring uninterrupted operation for long-running plants worldwide.

Deployed Across Global Process Industries
The CI854AK01 is widely deployed in industrial facilities using ABB System 800xA and AC 800M controllers, particularly in regions with mature infrastructure such as Europe, the Middle East, Southeast Asia, and Latin America.
Industries including oil & gas, power generation, chemicals, metals, pulp & paper, and water treatment frequently rely on this PROFIBUS-DP/V1 interface to maintain communication between controllers and distributed I/O systems installed years earlier.

PROFIBUS-DP/V1 Interface for AC 800M Systems
The ABB CI854AK01 is a PROFIBUS-DP/V1 communication interface module designed for integration with AC 800M controllers.
The package includes:
CI854 Communication Interface
TP854 Baseplate
With compact dimensions of 127.5 mm × 185 mm × 59 mm and a net weight of 0.59 kg, the module fits efficiently into existing control cabinets without requiring mechanical redesign.
It enables reliable cyclic and acyclic data exchange between the controller and PROFIBUS field devices such as remote I/O stations, drives, and intelligent instruments.

Ensuring Continuity for Installed Control Systems
Many industrial plants operate continuously for decades, making complete system replacement costly and risky.
The CI854AK01 exists specifically to support repair, reuse, functional updates, and capacity upgrades of pre-2017 installations.
For example, in a thermal power plant running 24/7, replacing a failed PROFIBUS communication module with CI854AK01 allows engineers to restore full I/O communication within hours, avoiding prolonged outages that could otherwise result in significant production losses.
For new installations, we recommends the RoHS-compliant successor CI854BK01 (3BSE069449R1).

Performance in Real Industrial Scenarios
In a chemical processing facility operating under high electromagnetic interference, the CI854AK01 enables stable PROFIBUS-DP/V1 communication between the AC 800M controller and S800 I/O stations across long cable runs.
During continuous operation, the module supports deterministic data exchange required for precise valve positioning, motor control, and safety interlocks.
Its compatibility with AC 800M Hardware versions 4.0 to 5.1 and System 800xA control software allows engineers to integrate the module seamlessly without modifying existing application.
As a small equipment device under WEEE Category 5, it also simplifies maintenance planning and inventory management for automation spare parts teams.

Conclusion
The ABB CI854AK01 PROFIBUS-DP/V1 Interface continues to play a critical role in sustaining legacy industrial automation systems worldwide.
By enabling reliable communication, supporting installed System 800xA environments, and minimizing downtime during maintenance or upgrades, the CI854AK01 remains a trusted solution for industries that prioritize stability, continuity, and operational efficiency.
For plants extending the life of existing AC 800M-based systems, this interface represents a proven and practical communication backbone.
