For decades, DCSs have formed the industrial equivalent of neuromuscular systems in factories and process plants worldwide. However, these automation architectures were designed as closed, monolithic systems with tightly integrated hardware and software stacks where control logic, data processing and visualization were tied to specific vendor platforms. Upgrading or expanding these systems often involved extensive engineering work, costly downtime and in many cases, complete system overhauls.

That rigidity became a real problem with the arrival of Industry 4.0, the Industrial Internet of Things (IIoT), cloud technology, edge computing, Big Data and data analytics − technologies with enormous potential that traditional DCS architectures struggled to accommodate.

In 2026, ABB launched Automation Extended to tackle this situation head-on. Automation Extended is a structured, future-ready approach to modernization that protects existing investments, maintains continuity and keeps mission-critical operations running smoothly.

Automation Extended is not a new DCS in the traditional sense, nor a bolt-on digital layer separate from control. Instead, it offers new capabilities to ABB’s existing automation platforms (specifically, ABB Ability™ System 800xA®, ABB Ability™ Symphony® Plus and ABB Freelance) through a modern, open and modular automation ecosystem, built specifically to support continuous innovation without disrupting core control functions.

Separating what matters

At the heart of Automation Extended is a principle called “separation of concerns.” The architecture is divided into two distinct but securely connected environments, each optimized for a different job and managed through a unified lifecycle service model that simplifies complexity and keeps operations continuously optimized.

The Control Environment handles what DCS systems have always done best: deterministic, real-time process control. It stays robust, lifecycle-resilient and cyber-secure, prioritizing availability, safety and reliability. This is where immediate responses for safe plant operations happen.

The Digital Environment is where the innovation takes place. This environment is a flexible, modular space for advanced analytics, AI-driven applications, condition monitoring, predictive maintenance, alarm management and decision-support tools. The user can deploy, update, or remove these capabilities without touching the core control functions.

This separation of‑ ‑concerns automation ecosystem, which is aligned with the NAMUR Open Architecture (NOA), is what distinguishes Automation Extended from earlier methods − by enabling each environment to develop through its own lifecycle, at its own pace, while staying securely connected.

Automation Extended is designed as an open, modular and software-focused ecosystem where applications are separated from hardware and can operate across distributed environments − whether on edge devices, on-premise servers, or in the cloud. Instead of being confined to proprietary systems, users can integrate third-party applications, incrementally scale functionality and adapt their automation infrastructure as their operational needs change.

OPC UA and Ethernet-APL

This move to a network-centric world is supported by the platform-independent OPC UA communication protocol, which provides a framework for real-time interoperability between different products and systems across the different layers of the automation pyramid.

Complementing OPC UA is Ethernet-APL − a secure, high-speed, two-wire, powered Ethernet networking solution designed for process automation.  One of the key benefits of Ethernet-APL is that it can provide power and communication to process instrumentation, including intrinsically safe applications.  It also reduces field wiring, solves traditional Ethernet bandwidth issues for comprehensive data transmission and facilitates seamless integration of existing fieldbus protocols with Ethernet-APL switches. 

Making data work harder

Data plays a central role in Automation Extended. Traditional systems tend to isolate data in silos, making it hard to get a holistic view of operations. In contrast, Automation Extended is designed to make data accessible, contextualized and actionable across the entire enterprise.

In practice, this means better decision-making, smarter predictive maintenance, energy optimization and process improvements. Machine-learning algorithms and analytics tools can work directly with live process data, surfacing insights that were previously difficult or impossible to obtain.

Security built in, not bolted on

Today, increased connectivity brings greater cyber security risks. Automation Extended integrates security-by-design principles, including secure communication protocols, role-based access control and continuous monitoring. This ensures that as systems become more open and connected, they stay protected against evolving threats.

Flexible lifecycles, less downtime

One of the biggest practical benefits of Automation Extended is its support for flexible lifecycles. In traditional setups, upgrading might mean replacing hardware, rewriting software and accepting operational downtime. With Automation Extended, updates happen gradually − new applications can be added, existing ones adjusted and outdated components swapped out without disrupting the entire system. The result is reduced downtime, lower costs and longer-lasting automation investments.

Opening the door to innovation

Automation Extended also promotes collaboration and innovation. By offering open interfaces and development environments, ABB allows not only its engineers but also customers, partners and third-party developers to build and deploy applications. This encourages a broader innovation ecosystem in which new ideas can be tested and implemented more quickly than in closed systems. It also helps organizations customize their automation solutions to meet their specific needs, rather than relying solely on vendor-provided features.

Ultimately, Automation Extended is not just an incremental improvement − it redefines industrial automation control architecture. By combining openness, modularity and data-centric design in this new ecosystem, greater flexibility, faster innovation and more efficient operations are achieved, while reliability and performance are maintained. This platform will help industries evolve successfully by growing and adapting alongside the businesses it supports.
