The three main types of HMI screens commonly used in industrial applications are:

1. Static Screens: Static screens are fixed displays that typically present information in a predetermined layout without much variation. They often display critical system parameters, status indicators, and basic controls. Static screens are useful for presenting essential information that doesn't change frequently, such as equipment status or operational modes.

2. Dynamic Screens: Dynamic screens are more interactive and can adapt their content based on user input or system conditions. They often include elements such as buttons, input fields, and dynamic graphics that allow operators to interact with the system. Dynamic screens are versatile and can display real-time data, trends, alarms, and other relevant information, providing operators with more flexibility and control over the industrial process.

3. Interactive Screens: Interactive screens take user interaction to the next level by offering advanced features such as touchscreens, gesture control, and multimedia capabilities. They enable operators to manipulate objects on the screen directly, perform complex operations, and access additional functionalities through intuitive gestures or commands. Interactive screens are especially beneficial for complex systems or processes that require a high level of user engagement and customization.

These three types of HMI screens cater to different needs and preferences in industrial settings, providing operators with the right tools to monitor, control, and optimize their processes effectively.
