Which objects appear on the display but do not interact with a PLC's data tags?

Static objects are those that appear on a display but do not interact with a PLC's data tags. These elements serve primarily as visual aids, providing context or information without engaging directly with the underlying control logic or data. Examples of static objects include labels, backgrounds, and decorative graphics that help enhance the user interface but are not designed for user interaction with the data or control actions of the PLC.

This concept is crucial in the design of human-machine interfaces (HMIs) where clarity and visual organization are essential for users to navigate through controls and information. Understanding the role of static objects helps in creating more effective displays that can present necessary information while minimizing potential confusion regarding which elements can be interacted with.
