In today’s industrial landscape—where time is money and flexibility are key—agility is essential. Recently, I heard a story about a leading specialty chemical manufacturer that replaced a cabinet full of dedicated IO modules with a single, software-configurable alternative to achieve greater agility. The outcome?
They were able to:
- Avoid downtime
- Save significant operational costs
- Streamline their design process
- Reduce delays
- Enable faster recovery when events did occur
You may think this is a story about cost-cutting, but it goes far beyond that. It’s about an important shift towards software-defined automation.
The legacy model that tied every function to a specific piece of hardware no longer fits today’s change-based realities. Software-defined automation eliminates bottlenecks in design, maintenance, and scalability—turning rigid architectures into adaptive systems. It decouples function from form, enabling dynamic control strategies that can evolve over time without requiring hardware removal or halting processes. This can mean different things for people throughout the organization:
- For C-level leaders, this means faster time-to-production
- For EPCs, it’s design flexibility
- For automation managers, it’s predictive maintenance and operational resilience
From hardware-constrained to business-aligned
Traditional control systems were rigid design models that were built for precision, not change. One module, one function. Analog input? One card. Digital output? Another. If a signal type shifts during commissioning, engineers must swap hardware, reorder parts, revise drawings, and revalidate everything. Schedules slip, costs climb, and flexibility vanishes.
These limitations aren’t theoretical; they have very real consequences. During the pandemic, lead times for IO cards stretched into months, stalling critical projects. In one case, a site was forced to redesign part of its system architecture simply because a specific module was unavailable.
These hidden “rigidity costs” show up everywhere in the form of:
- Design inflexibility: Even small changes trigger cascading rework.
- Inventory sprawl: Teams stock dozens of specialized modules—many of which are rarely used.
- Reactive maintenance: Without embedded diagnostics, faults often reveal themselves only during a shutdown.
Today, we have an IO layer where any channel can serve almost any function. This software-defined IO eliminates long-accepted obstructions and evolves with your business. It simplifies engineering and removes friction from the entire lifecycle. No rip-and-replace strategy needed; you can phase it in, module by module, wherever it delivers the most value.
Applying DevOps to industrial systems
What software-defined automation brings to the industrial world is a development operation (DevOps)-like agility. It allows hardware to be installed early, even before signal types are finalized. It also leaves room for late-stage adjustments through software configuration. In effect, it transforms the IO layer into a dynamic asset rather than a static constraint.
It also supports more modular physical architectures. With the use of fiber-optic communications, IO modules can be distributed into smart junction boxes closer to field instruments. This reduces cabling by up to 40 percent, simplifies installation, and enables teams to commission and expand systems without redesigning entire panels.
Operational benefits are equally significant. With fewer module types to train on and maintain, plant personnel can focus on performance rather than part numbers. Maintenance teams no longer need to guess whether a module is functioning correctly. Built-in diagnostics continuously monitor environmental conditions, signal quality, and line integrity. Unexpected failures become exceptions, not the norm.
Autonomy begins with adaptability
Autonomous operations remain a long-term goal for many industrial businesses, but the journey must begin with adaptable infrastructure. Without it, higher-level automation strategies, such as machine learning or closed-loop optimization, have nowhere to land.
A common progression is emerging:
- Standardization – Reduce variation and complexity at the hardware level
- Embedded intelligence – Integrate diagnostics and data at the edge
- Self-configuration – Enable systems that reconfigure themselves in response to changes or failures
This isn’t theory—it’s already happening with our customers. A refinery facing a late-stage control change during commissioning avoided a delay by updating IO assignments in software. No panel rewiring, hardware delays, or lost production time.
Meanwhile, a mining operator reduced spare part inventories by 70 percent and streamlined technician training by standardizing on a single type of universal IO. These are meaningful outcomes—and they demonstrate how software-defined systems quietly clear the runway for more advanced, autonomous behaviors.
The human factor
Technology alone doesn’t drive transformation—people do. And one of the benefits of software-defined automation is how it can empower human teams:
- Engineers gain flexibility without fear of rework.
- Maintenance crews face fewer SKUs, less complexity, and more reliable diagnostics.
- Operators get access to the kind of real-time data that enables smarter decisions.
- Executives gain a more future-ready plant—one that can adapt as goals shift, regulations tighten, or market conditions evolve.
In a time when skilled labor is challenging to find and harder to retain, software-defined automation creates systems that are easier to learn, maintain, and trust.
Enabling the transition
One of the technologies helping industry make this transition is EcoStruxure™ Foxboro DCS Edge IO, a foundational element in Schneider Electric’s open automation strategy. Each module in the Edge IO family supports a range of signal types, configured entirely in software. It integrates seamlessly with fiber-based distributed architectures, offering visibility that extends to the very edge of the process.
Importantly, Edge IO doesn’t require wholesale infrastructure replacement. It can be deployed gradually, augmenting existing systems where the need for flexibility, speed, or resilience is greatest.
Once paired with EcoStruxure Automation Expert, Edge IO delivers even more value—becoming a dynamic component of a fully software-defined, plug-and-produce architecture. This approach aligns with the broader vision of universal automation, a movement based on the IEC 61499 standard that promotes open, interoperable, and portable industrial systems.
As a founding member of UniversalAutomation.org, Schneider Electric is helping create a vendor-independent ecosystem where automation functions can be reused across projects, vendors, and platforms. Together, Foxboro DCS Edge IO and EcoStruxure Automation Expert bring that vision to life in real-world applications.
