Operator interface panel with control for visibility of desplayed objects

摘要

The invention implements a means of making objects visible or invisible on HMI display. The object's visibility can be under the user control and/or under the control of connected controller, thereby making the objects context-sensitive. Context-sensitive visibility helps in designing less congested screens thereby making them more operator-friendly. In addition said screens are safer as they eliminate unintentional activation of nearby controls, and eliminate unnecessary and unauthorized activation of controls.
