The Settings folder contains application files used by Canvas during each working session, which save information about global settings, control plugins, user settings, and workspace layouts, and are generated each time you close the application. If the current file is deleted, a new file will be generated upon closing Canvas.

An Object is a simple Canvas screen containing one or more controls, which can be used on one or many screens. The controls on an object might represent assets such as a well or compressor or device or facility. Once configured, you can drop an object onto many different screens. If you need to make a single edit to any one control on an object, you simply change the master object, save the object, and all screens containing that object will be automatically updated. Any change made to an object will affect all instances of that object on any Canvas screen where it is used. Objects are analogous to templated screens in CygNet Studio. An object and a screen share the same configuration properties, events, and methods.

• Click Object library to configure the contents of the Canvas object library.
• See Configuring Object Library for more information about configuring an object library.

Canvas supports navigation to a specific screen by selecting a CygNet facility. You can also specify optional facility record properties to be included when the navigation is triggered. This Navigation by Facility feature requires global configuration of the facility attribute that contains the path to the screen that will be displayed when the navigation via facility is requested.

• Click Facility navigation to configure the facility attribute that contains the associated screen.
• See Configuring Facility Navigation for more information about configuring the facility attribute and other properties.

For any given facility you can configure a relationship to define a path to another facility in your CygNet environment.

• Click Relative facilities to configure global relative facility definitions. These definitions are stored as XML but are encoded inside the global settings file (.gsf).
• See Using Relative Facilities for more information about relative facilities.
• See Configuring Relative Facilities for more information about configuring relative facility definitions.

A Canvas style consists of a set of properties with preconfigured property values for a particular control type. Style sheets allow you to quickly apply a predetermined style to any control added to a screen or object. By designing and using style sheets consistently you can make changes in one place and cascade those changes down to all Canvas screens in the CygNet environment. Style sheets allow for the creation of unique style guidelines for your enterprise, making screen design faster, easing the burden of screen maintenance, and improving operator experience. If you create more than one object with the same properties, it's a good idea to use styles to ensure consistency in design.

• Click Style sheets to configure styles sheets for Canvas controls.
• See Configuring Style Sheets for more information about creating and managing styles.

Canvas supports custom color palettes, which can be configured in the Canvas settings and then applied to any screen containing CygNet-aware controls.

CygNet supports a dual mode for point state color; that is, each point type allows both a background color and a foreground color to be set. The point state definition colors are configured in the CVS metadata file for each point scheme.

In CygNet-aware controls the color configuration for point state supports either background color or foreground color:

• Typically background color is used for the closed space on a control, for example, the background area, borders and lines, grid cells, bars and rings, markers, and fills. The default background color for the standard point scheme is configured from one of the following colors: green, cyan, magenta, yellow, or red.
• Typically foreground color is the element on the face of control, usually the text. For most point states, the default foreground color for the standard point scheme is black.

In Canvas you can create a custom color palette to override the default point state colors for any point type. If a custom color palette is selected for a screen, any CygNet-aware controls using Point State for color will apply the selected color palette in run mode.

• Click Color palettes to configure custom color palettes for use in CygNet-aware controls.
• See Configuring Color Palettes for more information about creating and managing color for point states.
