Which statement is true regarding the highlighted keys on the SR-2 HMI?

The highlighted keys on the SR-2 HMI are indeed known as "Soft Keys," which means their functions are dynamically controlled by the software based on the context of the operation. This adaptability is essential for providing the operator with relevant functions depending on the current operational mode of the unit.

In addition to their designation as soft keys, the functionality of these keys can indeed change according to the mode of operation. This means that when the user switches between different modes, the roles assigned to these keys can reconfigure to provide the appropriate controls for that specific scenario.

Moreover, the current functions of the soft keys are displayed directly above them on the HMI display screen. This feature ensures that the operator can easily understand what each key will perform at any given time without having to memorize or reference an external guide.

Combining all these points together, it is clear that each statement is valid and contributes to a fuller understanding of how the SR-2 HMI operates, leading to the conclusion that all statements about the highlighted keys are true.
