Layout Manager: Refresh Rate Up to 60 Hz

Component Specifications

Definition

A specialized software component within industrial Human-Machine Interface (HMI) systems that dynamically manages the positioning, scaling, and organization of graphical elements (such as buttons, indicators, graphs, and alarms) on operator screens. It ensures optimal information presentation based on screen resolution, user roles, and operational context to enhance usability and efficiency in industrial control environments.

Working Principle

The Layout Manager operates by defining a hierarchical structure of containers and widgets. It uses algorithms to calculate optimal positioning based on constraints (like screen size and aspect ratio), user-configurable rules (like grid systems or anchor points), and real-time data (like alarm priorities). It dynamically adjusts element sizes and positions during runtime to maintain readability and accessibility, often supporting responsive design principles for various display devices.
