HMI/SCADA from Scratch with Delphi and Lazarus

Summary: Learn the fundamentals of building your own monitoring and control (HMI/SCADA) applications using Delphi and Lazarus. In this hands-on workshop, we will start from scratch to implement communication with industrial protocols, manage real-time data, and design a functional graphical interface. The concepts are 100% applicable to both IDEs, giving you total control over your automation projects, whether commercial or open-source.
