The Open Process Automation Forum strives for a software-defined industrial control system where the hardware and software are dissociated. The specific reason is that upgrades become less expensive. Software must be upgraded more often than hardware in a control system. If the two are tied together as in all proprietary control systems, then upgrades run on a continuum from painful to impossibly expensive.
I’ve been puzzling out this press release from Schneider Electric about a new control software dubbed EcoStruxure Automation Expert. The company says, “it is the world’s first software-centric industrial automation system.” I’m not sure that claim would stand up exactly, but it seems to me that this is a step on that journey toward dissociating software and hardware in the control system. Executives have told me in the past few years that achieving this is an essential long-term strategy.
Any comments you all have about this are welcome (as long as they’re civil and enlightening).
The press release is written in the tone of a challenge to the rest of the industry to write “apps” that will run on this standards-based (IEC-61499) system.
Schneider Electric promises to unleash a new wave of innovation by championing the widespread adoption of open automation standards unveiling its vision for universal automation with EcoStruxure Automation Expert, “a new category of software-centric industrial automation system.”
Claims closed and proprietary automation platforms restrict the adoption of best-of-breed technologies, present challenges to integrate third-party components, and are expensive to upgrade and maintain. Industry has suffered from a lack of adaptability, modularization and interoperability, which is stunting innovation.
Universal automation is the world of plug and produce automation software components based on the IEC61499 standard that solve specific customer problems in a proven way. Adoption of an IEC61499-based standardized automation layer, common across vendors, will provide limitless opportunities for growth and modernization across industry.
By greatly extending the capabilities of existing IEC61131-based systems and enabling an app-store-like model for automation software components, Schneider Electric believes that the advancements possible in the Fourth Industrial Revolution will be fully realized. As its benefits become visible, Schneider Electric believes other vendors will adopt the universal automation approach, and end users will soon begin to demand it from their automation suppliers and ecosystem.
“The IT world has realized the benefits of open operating platforms; now it’s industry’s turn,” said Peter Herweck, executive vice president industrial automation, Schneider Electric. “Industrial automation architectures have done a good job of advancing industry to where we are today, but they are not capable of providing the agility and resilience that are paramount for modern industrial operations. To fully realize the promise of the Fourth Industrial Revolution, we need to reimagine our technology model by opening our platforms, decoupling software from hardware, and radically improving system agility and scalability.”
EcoStruxure Automation Expert is a new category of industrial automation system with IEC61499 at its core. EcoStruxure Automation Expert:
- Enables automation applications to be built using asset-centric, portable, proven-in-use software components, independent of the underlying hardware infrastructure.
- Allows the user to distribute applications to any system hardware architecture of choice —highly distributed, centralized, or both — with minimal to no additional programming effort.
- Supports established software best practices to simplify the creation of automation applications that interoperate with IT systems.
The first release of EcoStruxure Automation Expert supports traditional automation platforms, such as Modicon PLCs, and Altivar Variable Speed Drives and PCs. Completing the line-up, a virtualized software controller running in Docker-powered Linux containers supports distributed information and control systems across edge computing architectures.
Leveraging the object-oriented nature of IEC61499, software components known as Composite Automation Types (CATs) are used to model assets by combining real-time control functions with other facets, such as the human machine interface. This asset-centric approach delivers unprecedented cost and performance gains and frees engineers to innovate by automating low-value work and eliminating task duplication across tools. Benchmarking of EcoStruxure Automation Expert against today’s automation systems has demonstrated a 2 to 7X reduction in the time it takes to perform traditional automation tasks.
EcoStruxure Automation Expert’s support for mainstream IT best practices enables step-change improvements in asset and workforce efficiency using advanced technologies like predictive maintenance and digital twin. The system also reduces total cost of ownership by incorporating legacy systems with a wrap-and-reuse approach.
“EcoStruxure Automation Expert is the first step in the journey toward universal automation” said Fabrice Jadot, senior vice president, next generation automation, Schneider Electric. “To fully realize the potential of next-generation industries, we must embrace a new way of thinking. Working to common, open standards is vital to ensuring multivendor interoperability and seamless interfaces from supply chain through manufacturing and production to the end customer. Now is the time for all vendors to fully embrace open implementations with code and function portability to become more connected. Today is the first step in a new direction. We invite industrial developers everywhere to create their own software components and solutions based on the IEC61499 standard, which can easily interoperate with EcoStruxure Automation Expert.”
