SCADA Tutorial #10 | Scripts (Part 2/2) | Screen Events, Object Control & Timer Logic

đź“Ś In the second video of the Wise SCADA scripting training series, we explore how written scripts interact with visual screen objects and how these objects can be controlled dynamically during Runtime.

This lesson focuses on Screen Script logic, event-driven execution, mouse events, timer usage, and advanced runtime object manipulation. You will learn how scripts behave when attached to screen events and how to build more interactive and flexible SCADA user interfaces.

⚠️ Important: To fully understand the topics covered in this lesson, we strongly recommend watching Part 1 (Part 1/2) of the series first.
