What is the primary focus of software-defined automation (SDA)?
Sarah McGhee, product owner, Simatic AX, Siemens: The primary focus of software-defined automation (SDA) is to leverage proven methodologies from the software development space and apply them to the OT space. This focus can be broken down into several key pillars:
- Integration of IT-oriented tools: Utilizing IT-oriented tools brings software engineering practices into the automation programming space. While automation does not always allow for the “fail fast and break things” approach typical in software development, it should enable rapid iteration in a safe manner.
- Virtualized programmable logic controllers (PLCs) and controls: With the creation of virtualized PLCs, we are concretely decoupling control tasks from hardware devices and providing the ability to run them on high-performance industrial PCs or computers, increasing flexibility and scalability. This approach also facilitates easier integration with other applications.
- Data-driven production: Leveraging data collected from automation systems to make intelligent decisions or suggestions is critical. With the addition of artificial intelligence (AI) models, it is essential to utilize data effectively to enhance automation systems. For example, predictive-maintenance algorithms can analyze data to foresee equipment failures and optimize maintenance schedules.
In summary, SDA focuses on integrating IT tools, virtualizing control systems and utilizing data-driven approaches to create more flexible, scalable and intelligent automation solutions (Figure 1).
