When interacting with an HMI panel, what does a technician engage with to monitor or test a process?

When monitoring or testing a process through an HMI (Human-Machine Interface) panel, a technician primarily engages with objects. In the context of HMI design, objects refer to graphical representations or controls on the screen, such as buttons, sliders, gauges, and indicators. These objects are designed to provide intuitive access to real-time process data and control functionalities.

By interacting with these objects, technicians can visualize the current state of a process, receive alerts, and execute commands such as starting or stopping machines. The effectiveness of an HMI in facilitating user interaction relies heavily on how well these objects are designed and organized to reflect the dynamics of the underlying systems they represent.

Monitoring and testing effectively require a direct interface with these graphical elements, enabling technicians to perform their tasks and respond to system feedback efficiently.
