Screens and graphics

The most basic function performed by AVEVA Edge is to provide a window into the process. The ability to display the status of the process by interacting with instrumentation (or computers), is described as the Human-Machine Interface (HMI).

AVEVA Edge allows you to create projects that can monitor processes using high-resolution color screens.

The AVEVA Edge graphic tools consist of two modules:

• The Screen/Worksheet Editor in the AVEVA Edge development environment (used to create or import graphics); and

• The runtime project Viewer.

You can use animations to create dynamic graphic objects or symbols. Animations cause objects and symbols to change appearance to reflect changes in the value of a tag or an expression. Each screen is an association of static and animated objects.

Screens can have an optional bitmap that acts as a background in the object window. On the following screen for example, the static images can be part of a bitmap in the background object and objects with animation in the animation object layer can reflect the changes in the plant, giving the illusion that the screen is three‑dimensional.

All AVEVA Edge configuration tasks require a Windows-compatible pointing device, such as a mouse or touch pad. You can run a project in the Viewer without a pointing device if you configure keypad or keyboard keys for all commands.
