Element styles details

A Galaxy Style Library includes pre-defined and user-defined element styles, plus numerical format styles and special characters used to show exceptions at runtime.

• Pre-defined element styles

  Pre-defined element styles have been configured with default values. You can modify each element style's font, fill, line, and outline properties.

  Pre-defined element styles are organized in groups belonging to the Element Style Overrides list by their functional purpose:

  • Quality and Status

  • HMI Elements

  • Alarm Elements

  • Trend Elements

    Many of the element styles apply to the graphic elements that comprise Situational Awareness Library graphics. An element style can define the visual properties of a graphic like its background color. An element style can also indicate a graphic's current operating state. For example, there is a set of pre-defined element styles that set the visual characteristics of machinery alarm states represented by a graphic.

• User-defined element styles

  User-defined element styles do not contain preset font, fill, line, and outline properties. You must specify each pre-defined element style's properties to meet the needs of your applications.

• Format styles are applied to numerical values, such as set points and process variables. There are pre-defined styles for real, Fixed Decimal, Integer, Exponential, Hex and Binary numbers. You can also configure user-defined formats. Format styles define range and precision for values.

• Special characters define two different special characters that are shown in alarm mode at runtime for the following conditions:

  • Bad quality with no value: default character is "!" (exclamation point)

  • Value too large for fixed field: default character is "*" (asterisk)

You can create your own Galaxy Style Library by overriding the default style configurations and exporting the library. For information about setting element style overrides, see Change the visual properties of an element style (, ).

If you want to restore the original default visual properties for your graphic elements, each of the styles pages includes a Reset to Default button. The UI Theme page does not have a button to restore the default setting.
