Perspective - Moving Analog Indicator

Component Palette Icon:

Description

The Moving Analog Indicator displays an analog value in context with other information about that value so that you can visually and quickly see if the value is in the normal range or not. The current value is shown as an arrow pointing at a bar with segments showing the desired operating range, low and high alarm ranges, and interlock ranges.

The Moving Analog Indicator component allows for extremely fast information delivery. At a glance, it is obvious to an operator whether or not the value is where it should be, or if it needs attention. If the value is in one of its alarm ranges, then that range can be set to change color to get attention.

Component Events

The Perspective Event Types Reference page describes all the possible component event types for Perspective components. Not all component events support each Perspective component. The Component Events and Actions page shows how to configure events and actions on a Perspective component. Component scripting is handled separately and can be accessed from the Component menubar or by right clicking on the component.
