Open Automation Is Reshaping Industrial Control Systems
Industrial automation is moving toward more open and software-centric architectures. Manufacturers increasingly need flexible control systems, better data access, and simpler system integration.
Traditional PLC and DCS architectures often depend heavily on dedicated hardware and proprietary engineering environments. Open automation takes a different approach by separating software functions from specific hardware platforms.
This model can improve interoperability across PLC, DCS, SCADA, and other factory automation systems. Moreover, it can help manufacturers adapt control applications as production requirements change.
However, technology alone cannot guarantee successful deployment. Engineering teams need practical experience with system architecture, application development, testing, and commissioning.
EcoStruxure Automation Expert Supports Open Automation
Schneider Electric is expanding its partner ecosystem around EcoStruxure Automation Expert (EAE). The platform uses the IEC 61499 standard as a foundation for distributed automation applications.
IEC 61499 supports a more modular approach to industrial control software. Engineers can organize control functions into reusable components and distribute applications across suitable computing resources.
This approach differs from traditional PLC programming models based primarily on fixed hardware execution. Therefore, it can support more flexible application architectures for complex automation projects.
For industrial users, the main value lies in architecture flexibility rather than software novelty. Open control environments can reduce dependence on a single hardware configuration when properly engineered.
Automation Partner Accelerators Build Engineering Skills
Schneider Electric organized Automation Partner Accelerator events between February and June 2026. The program reached more than 400 professionals from over 215 partner organizations.
The initiative covered participants across nine countries. Schneider Electric designed the sessions around practical engineering and commercial requirements.
Participants examined system architecture and application design during hands-on sessions. They also developed applications using reusable software libraries.
Configuration and orchestration formed another major part of the training. Testing, validation, and commissioning activities helped connect software development with actual automation project execution.
The program also addressed commercial considerations. Partners explored ways to explain open automation benefits and adjust their offerings to changing customer requirements.
System Integrators Become More Important in Open Automation
The move toward software-defined automation increases the responsibilities of system integrators. End users still need engineering teams that understand both operational requirements and automation technology.
A system integrator must evaluate control architecture, communication networks, application structure, cybersecurity, and lifecycle requirements. These decisions directly influence system performance and long-term maintainability.
In PLC and DCS projects, integration problems often appear between engineering disciplines. Open architectures can reduce some restrictions, but they do not eliminate engineering complexity.
Therefore, integrators need strong knowledge of control systems and industrial communication technologies. They must also understand how software components interact with physical I/O, controllers, drives, and field devices.
Why Interoperability Matters for Factory Automation
Interoperability has become a major consideration as factories combine equipment from different suppliers. Modern production lines may include PLCs, robots, drives, vision systems, historians, and edge computing platforms.
Proprietary architectures can make cross-platform integration more difficult. Open approaches can provide greater flexibility when engineers need to connect different systems.
However, interoperability requires more than supporting common communication protocols. Engineers must also address data models, application behavior, timing, diagnostics, and lifecycle management.
From a practical engineering perspective, standardized software structures can become valuable when plants operate multiple production lines. Reusable application components can shorten engineering work and simplify future modifications.
Software-Defined Automation Changes the Engineering Model
Software-defined automation shifts some engineering attention from hardware configuration toward application architecture. This change resembles broader developments in industrial computing and IT infrastructure.
Control functions can become more modular and portable. As a result, organizations may gain additional options when selecting computing and control hardware.
However, deterministic control requirements remain important. Motion control, high-speed processes, safety functions, and time-critical applications still require careful hardware and network design.
For this reason, software-defined automation should not replace engineering fundamentals. Instead, it should complement established PLC, DCS, safety, and industrial networking practices.
Practical Experience Remains Critical During Commissioning
Training can provide a foundation, but project experience remains important. Engineers must deal with actual field conditions during installation and commissioning.
Real plants rarely match engineering assumptions perfectly. Network behavior, instrumentation errors, legacy equipment, process constraints, and maintenance requirements can affect system performance.
Experienced integrators therefore validate applications before full production deployment. They also establish clear testing procedures and commissioning documentation.
This practical discipline becomes particularly important when organizations introduce new automation architectures. A technically flexible platform still requires structured engineering and controlled change management.
Schneider Electric Strengthens Its Partner Ecosystem
The Automation Partner Accelerator program reflects a broader industry trend. Automation suppliers increasingly depend on capable partners to deliver complex digital and control projects.
For Schneider Electric, stronger partner capabilities can support wider adoption of EcoStruxure Automation Expert. Partners gain technical knowledge while end users gain access to trained engineering resources.
Moreover, partner development can reduce the implementation barrier for open automation technologies. Customers are more likely to consider architectural changes when qualified engineering support exists.
In my view, this partner-focused strategy is as important as the underlying software platform. Open automation requires an ecosystem that can design, implement, maintain, and upgrade the technology.
Open Automation Does Not Eliminate PLC and DCS Systems
The growth of software-defined automation does not mean traditional PLC and DCS systems will disappear. These technologies remain deeply established across process, discrete, hybrid, and infrastructure applications.
Instead, the industry is moving toward greater coexistence between conventional controllers and software-centric architectures. Plants will continue using established control platforms while adopting new technologies where they provide measurable benefits.
The most practical approach is therefore application-driven. Engineers should select an architecture according to process requirements, lifecycle costs, integration needs, and operational risk.
Application Scenario: Multi-Vendor Factory Automation
Consider a manufacturing plant operating PLC-based production lines from several equipment suppliers. The plant also uses drives, robots, SCADA software, historians, and energy monitoring systems.
An open automation strategy can provide a framework for integrating these systems. Engineers can create reusable software functions while maintaining connections with existing equipment.
The plant can then standardize selected application functions across multiple production areas. This approach may simplify future expansion and reduce duplicated engineering work.
However, engineers should first identify integration boundaries and performance requirements. They should then validate communication, diagnostics, cybersecurity, and commissioning procedures before wider deployment.
Application Scenario: Modernizing Existing Control Systems
Another use case involves modernizing an established factory without replacing every controller. The organization can gradually introduce software-defined automation alongside existing PLC or DCS infrastructure.
This phased approach can reduce disruption to production. It also allows engineering teams to evaluate new architectures against real operational requirements.
In such projects, migration planning becomes particularly important. Engineers should document existing control functions, interfaces, alarms, sequences, and maintenance procedures before making architectural changes.
ARC Perspective: Skills Will Influence Adoption
The expansion of open automation depends on more than standards and software platforms. The industry also needs engineers who understand how these technologies behave in production environments.
Schneider Electric’s partner training initiative addresses this practical requirement. Its focus on architecture, reusable applications, configuration, testing, and commissioning aligns with the real workflow of automation projects.
From an industrial automation perspective, this is a sensible direction. Technology adoption becomes easier when system integrators can demonstrate measurable engineering and operational benefits.
The long-term question is whether open automation can deliver these benefits consistently across different industries. Its success will depend on interoperability, engineering quality, lifecycle support, and the availability of skilled professionals.
Conclusion: Engineering Capability Will Shape Software-Defined Automation
Software-defined automation is becoming an important direction for industrial control systems. It offers a path toward more modular applications and greater hardware flexibility.
Schneider Electric is strengthening this transition through EcoStruxure Automation Expert and its partner development activities. The Automation Partner Accelerator program demonstrates the importance of building practical engineering capabilities alongside technology.
For manufacturers, the decision should focus on measurable operational requirements rather than technology trends alone. PLC, DCS, and established control systems will continue to serve important roles.
However, open automation can provide additional architectural options for organizations pursuing flexible and interconnected factory automation. The strongest results will come from combining open technologies with disciplined engineering and experienced system integration.
