Understanding Ladder Logic vs. Structured Text in OT

In this engaging discussion, we address a common debate in the field of Operational Technology (OT): Ladder Logic versus Structured Text. Our guest, an experienced software developer, shares his perspective on why the focus on programming languages often misses the more critical aspects of software development.
We start with a question from Sandro about troubleshooting at the plant level and use it as a springboard to discuss broader issues. Our guest argues that the language used-whether Ladder Logic, Structured Text, or another-should not overshadow fundamental software development practices that ensure quality and reliability. Drawing from extensive experience and industry reports, he emphasizes the importance of practices like test-driven development and automated testing, which are language-agnostic and crucial for creating robust, maintainable software.
Explore how these practices can be applied in OT environments, regardless of the specific programming language. Learn about the benefits of modularity, reusable libraries, and the value of automated regression testing. Our guest also addresses practical concerns, such as the need for operators to interact with the code in real time and the challenges posed by manual testing methods prevalent in the industry.
Whether you're an OT professional, a software developer transitioning to OT, or simply curious about the interplay between different programming languages in industrial settings, this video offers valuable insights. Join us as we shift the focus from the language debate to the essential practices that drive software excellence in the OT world.
