1. In design mode, create a new Canvas screen or object.
2. Find the image control on the Toolbox pane and drag a desired object to your screen.

3. Use the Settings pane to apply common settings (sizing, grouping, alignment, etc.) to this object (and others) on your screen.

4. Optionally, use the Name property to rename the object if you plan to reference it in another screen or control, or plan to script this control.
5. Configure the Style property.

1. Style —

   The Style property defines the style sheet applied to an object on a screen. A style sheet consists of a predetermined list of properties and property values configured for a particular control type.

   • Click to reveal a drop-down menu of predetermined styles configured for the selected control.
   • Select a desired style and its properties will be applied to the control.
   • Alternately, you can create a new style based on other property values configured for the control.
   • Or you can select <None> to remove subscription to any style.

   Styles are created in two ways:

   • In the control's Properties pane. Click (Add a new style based on this control) next to the Style property, after you have configured property values in the Properties pane. See Add a new style based on a control for more information.
   • In the Canvas Settings in the Backstage view. The default style for any control is configured in the Backstage view. See Manage style sheets in the Backstage view for more information.

   Tip: You can also change a control's Style on the Controls view of the Screen pane.

6. Configure the Location properties. See To configure location, size, resizing, layer, and visibility properties below.
7. Configure the Script property.

1. Include in script —

   The Include in script check box indicates that the control will appear in the objects collection of the screen (if scripting is enabled). To optimize performance, best practice dictates that you only include the controls you need to manipulate via script. Other controls should be excluded. When you add an event to a control, it will be automatically added to script and the Include in script property (and the In Script check box on the Controls view) will be set to True.

   Tip: You can also change the Include in Script setting on the Controls view of the Screen pane.

8. Configure the point Value properties. Value properties include date and time format, hide invalid tag, point configuration, show context menu, and value format properties. See To configure the point value below.
9. Configure the Image properties to configure a static or CygNet-aware image on the control. See To configure the image properties below.
10. Configure the Font Properties. See To configure font properties below.
11. Configure the Display property:

1. Mouse cursor — The Mouse cursor property determines which mouse cursor will appear when the mouse hovers over this control or map visual. Select an option from the drop-down menu: Arrow (), Hand (), Wait (), or Help (). The default cursor is the Arrow ().
2. Suppress data retrieval — The Suppress data retrieval check box indicates whether all CygNet data retrieval is suppressed for the control or map visual. Use this if you want to store point information in the control but don't want to automatically query services for data. Tokens will not be replaced and point state colors will be ignored.You can configure the control with a valid point configuration but the control will not retrieve any CygNet data. This allows you to display static text for a control, while still allowing CygNet data context available from script.If a control has a point configured, but Suppress data retrieval is enabled, Canvas won’t do much point processing. The one exception is point validity. If the control is configured to Hide invalid tag, then Canvas will check if the current tag is valid, even if Suppress data retrieval is enabled. This will allow you to configure some static text that will dynamically hide in the case of a templated screen for a facility that doesn’t have that particular point.
3. Text — The Text property specifies the text that will appear on the face of the control. The item can display a static text string, such as a label, legend, tooltip, or a dynamic text string based on point or facility attributes. Dynamic text is built using tokens, which can represent real-time CVS point properties, point configuration properties, and facility properties. In run mode, the tokens are replaced with the attribute's value. Click to configure the static text and/or property tokens using the CygNet Property String dialog box. For most controls there is no default. For the Detail, Donut, and Tile View controls the default value is the %Value% token.

   Note: Point data and/or text will display in run mode, even if the no image is specified and the missing image icon () is displayed.

12. Configure the Tooltip properties. See To configure tooltip properties below.
13. Configure the Generic properties:

1. String — The String property specifies a generic string property that can be used when scripting this control. Type a string and reference it in your script as necessary.
2. Yes/No — The Yes/No property specifies a generic Boolean yes/no property that can be used when scripting this control. Click the check box to enable the property and reference it in your script as necessary.

14. Configure the General properties to configure the basic properties of the object.

1. Visible — The Visible check box indicates whether the control is visible in run mode.Tip: You can also change a control's Visible setting on the Controls view of the Screen pane.

15. Configure other image properties.
16. Save the screen.
17. Run the screen to test your configuration.

1. Find the Location properties and configure the size and location properties for the control:

1. Height —

   The Height property specifies the height of the control (or screen).

   Tip: You can also change the height of a control using the Settings pane (click on the (Settings) to the right of the control in design mode) or on the Controls view of the Screen pane.

2. Horizontal resize mode —

   The Horizontal resize mode property specifies whether and how the control dynamically moves or resizes horizontally when the screen is resized in run mode. Options include:

   • None — No resizing occurs.
   • Shift — The object will shift horizontally.
   • Expand — The object will expand or shrink horizontally the same number of pixels as the screen.
   • Proportional — The object expands or shrinks proportionally to the screen.

   The default value is None.

3. Layer —

   The Layer property specifies the name of the layer to which this object is assigned. Layers can be used to show, hide, and edit multiple controls on one layer without affecting controls on another layer.

   • Type the name of the layer into the Layer field (the name can be a previously created layer or a new layer).
   • All layers are listed on the Layers pane, where you can manage the layers for the screen in design mode and run mode.

   Tip: You can also edit a control's Layer on the Controls view of the Screen pane.

   Note: Layer visibility can be controlled at runtime via the AddLayer, HideLayer, SetLayerVisibility, and ShowLayer methods on the Screen object.

4. Lock —

   The Lock property indicates whether the control is locked to the current position. A locked control cannot be moved via click and drag, or nudged with the arrow keys, or resized.

   Tip: You can also toggle the lock setting of a control using the Settings pane (click on the (Settings) to the right of the control in design mode).

5. Vertical resize mode —

   The Vertical resize mode property specifies whether and how the control dynamically moves or resizes vertically when the screen is resized in run mode. Options include:

   • None — No resizing occurs.
   • Shift — The object will shift vertically.
   • Expand — The object will expand or shrink vertically the same number of pixels as the screen.
   • Proportional — The object expands or shrinks proportionally to the screen.

   The default value is None.

6. Visible —

   The Visible check box indicates whether the control is visible in run mode.

   Tip: You can also change a control's Visible setting on the Controls view of the Screen pane.

7. Width —

   The Width property specifies the width of the control (or screen).

   Tip: You can also change the width of a control using the Settings pane (click on the (Settings) to the right of the control in design mode) or on the Controls view of the Screen pane.

8. X —

   The X property specifies the location of the control along the horizontal axis. Use the up, down, left, and right arrow keys to nudge a control by 1 pixel. Arrow moves a control by 1 pixel. Ctrl+Arrow moves a control by 10 pixels. Ctrl+Shift+Arrow moves a control by 100 pixels.

   Tip: You can also change the location of the control using the Settings pane; click on the (Settings) to the right of the control in design mode.

9. Y —

   The Y property specifies the location of the control along the vertical axis. Use the up, down, left, and right arrow keys to nudge a control by 1 pixel. Arrow moves a control by 1 pixel. Ctrl+Arrow moves a control by 10 pixels. Ctrl+Shift+Arrow moves a control by 100 pixels.

   Tip: You can also change the location of the control using the Settings pane; click on the (Settings) to the right of the control in design mode.

10. Z index —

    The Z index property is used to determine the order in which controls are layered on top of each other. Controls with higher values will draw on top of those with lower values. The newest control added to a screen will always have the highest value and will be the top layer. Two or more controls can be on the same index (layer).

    Tip: You can also change the Z index of a control using the Settings pane (click on the (Settings) to the right of the control in design mode) or on the Controls view of the Screen pane.

2. Configure any other image properties.
3. Save the screen.
4. Run the screen to test your configuration.

The source of CygNet data for the control can be explicitly configured <Self> or it can be received from the screen or another control. Also configurable is the control's date, time, and value format, whether to display a context menu where you can acknowledge alarms interact with other CygNet information.

1. Find the Value properties and configure the date and time format, invalid tag display, point configuration, context menu display, and value format properties of the control.

1. Context menu items — See To configure custom context menu items below.
2. Date and time format —

   The Date and time format property specifies the format for a point's timestamp using any of the valid .NET standard or custom numeric format strings. The date and time format applies to any point's timestamp property. Use this property to override the Default date format, which is configured in the Application settings page of the Backstage view. The default date format is YYYY/MM/DD HH:MM:SS.fff, which corresponds to 2024/01/01 10:20:30.0001. All timestamps are local client time.

   If an invalid format is configured for the Date and time format, the control will automatically use the format configured for the Default date format saved in the global settings file, and configured in the Backstage view.

   Note: You can also use the Microsoft .NET Standard Date and Time Format Strings to define the text representation of a date and time value in Canvas. For example, "d" is the short date pattern and corresponds to 1/1/2024, "F" is the full date/time pattern and corresponds to Monday, January 1, 2024 1:45:30 PM.

3. Hide invalid tag —

   The Hide invalid tag check box indicates whether to hide the element (a control, button, image, or map visual item) if it resolves to an invalid or unknown tag.

   Note: Invalid point tags and relative facility resolution work in the following way for single-value controls: when a point tag is invalid or unknown, the tag can be hidden using the Hide invalid tag property. In this situation, a control with only facility-based tokens that has a valid relative facility resolution, but results in an invalid point tag, then the point tag will be treated as an invalid tag and displayed accordingly.

   There may be a scenario where you want to hide a control when using facility-based attributes and relative facilities. Say you have a templated screen with a Text Tool displaying a Gas Meter, but not all Wells have an associated Gas Meter. You could hide the control for a Well that does not have an associated Gas Meter, and by not specifying a UDC, you can always show (or hide) a facility resolution with facility-based attributes only.

4. Point configuration — The Point configuration property is used to configure the CygNet point associated with the control. Click to reveal a drop-down area where you can configure the Selection mode, source Facility tag, source SiteService, source Facility, and the UDC or Long Point ID for the point. Each option is described below.

   Note: Point data and/or text will display in run mode, even if the no image is specified and the missing image icon () is displayed.

1. Selection mode —

   The Selection mode property is used to determine how the control will receive CygNet information from other controls or from itself. Two options are available; click the desired radio button:

   • Facility tag — The Facility tag selector consists of a Source chooser and Resolve to a relative facility check box. If the Source is <Self> a Facility tag selector and relative facility options are also displayed. Facility tag is the default option.
   • SiteService / Facility — The SiteService / Facility selector consists of Source and SiteService and facility choosers.

   Sending and receiving facility tags

   Some controls on the same screen allow for the sending of facility information from one control to another.

   1. On the sending control configure the Facility sender mode property to send facility tag information to another control on the same screen.
   2. On the receiving control configure the Selection mode property (in either CygNet connection or Point configuration section) to Facility tag and select the Facility Source to the sending control.
   3. On the receiving control configure a display tag that associates to a facility property, e.g., %FacilityTag%.

   Example

   Add a control to a screen (e.g., a Tag Chooser or Grid) and configure it as a facility sender to send a facility to the screen. Add another control to the screen (e.g., a Text Tool or Donut) and configure it to receive the facility from the screen. In this scenario the Tag Chooser or Grid will send a facility to the screen and the screen will then send the facility to a Text Tool or the Donut.

2. SiteService — The SiteService property is where you specify the source of the SiteService for the control (or screen) to use. The source for the SiteService can be explicitly configured for this control or it can be received from another control on the same screen, or from the screen, or from another screen. Click to reveal the SiteService selector. Options include:
• Source — Options include <Self> or Screen (default):
  • <Self> — Select <Self> to explicitly configure the SiteService for this control or screen element. A SiteService selector is displayed:
    • SiteService — The SiteService property specifies the SiteService for which the control (or screen or screen element) is to display data. Click to select a service using the Select Service dialog box.
• Screen — Select Screen to receive the SiteService from the screen for this control or screen element. By default, the sender is the Screen control if no other senders have been configured.

3. Facility — The Facility tag or Facility property is where you specify the source of the facility for the control (or screen) to use. The source for the facility can be explicitly configured for this control or it can be received from another control on the same screen, or from the screen, or from another screen. Click to reveal the Facility tag or Facility selector. Options include: Click to reveal the Facility selector. Options include:
• Source — Options include <Self>, Screen (default), or a list of Sender controls.
• <Self> — Select <Self> to explicitly configure the facility for this control. A Facility tag or Facility selector is displayed, depending on the Selection mode:
  • Facility — The Facility property specifies the facility for which the control (or screen) is to display data. Click to select a facility using the Select Facility dialog box.
  • Facility Tag — The Facility tag property specifies the full facility tag identifier for which the control (or screen) is to display data. Click to select a facility using the Select Facility Tag dialog box.
• Screen — Select Screen to inherit the facility from the screen for this control. By default, the sender is the Screen control if no other senders have been configured. Once Screen is selected Inherited from Screen will display for the Facility property.
• Sender — A list of sender controls that have been configured with a facility will be displayed. Select the name of the control that will send its facility to this control. By default, the sender is the Screen control if no other senders have been configured. Once a sender control has been specified its name will display in the Source field.
• Resolve to a relative facility — The Resolve to a relative facility check box redirects the source of the facility to a relative facility, overriding the configured source facility. Once selected a list of configured Relative links is displayed. See Using Relative Facilities in Canvas for more information about configuring and scripting relative facility links.
  • Relative link — The Relative link property specifies a list of all available relative facility paths. Click to reveal a drop-down menu of all available relative facility definitions (relative links). Select a link from the list. If an order-in-type attribute is specified for the selected link, the Order in type field will display.
  • Order in type — The Order in type property specifies the attribute value used to represent the order in type (facility ordinal) if the relative facility definition is configured for one. It is possible to have multiple relative facility definition sets with the same definition name. In this case, if the specified Relative link is configured for ordinalization, then you need to configure the attribute value in the box.

4. Point —

   The Point property is used to determine how the CygNet point will be configured. Click the appropriate radio button to reveal the desired field.

   • UDC — The UDC property specifies the UDC for which the control is to display data. Click to select a UDC using the Select UDC dialog box.
   • Long point ID — The Long point ID property specifies the long point ID of the CygNet point for which the control is to display data. Type the tag into the field.

5. Show context menu — The context menu can be disabled at the control level.

   The Show context menu check box indicates whether a right-click context menu will be available or suppressed in run mode. The default context menu will allow alarm acknowledgment, access to point history and alarm history, point configuration, and facility configuration.

   Note: The CygNet Thin Web Client supports its own context menu in the web view. When activated the context menu appears on the right side of the page. From the CygNet TWC web view context menu you can view point values, acknowledge a point in alarm, view and edit alarm values, and add a selected point to an ad-hoc chart. See Using the Thin Web Client Context Menu.

6. Value format — The Value format property specifies the format for the point's value using any of the valid .NET standard or custom numeric format strings. The value format applies to a point's Value, Primary Value, and Alternate Value properties. The default value format is #,##0.00, which corresponds to 123,456,789.12. Formats use # and 0, with a period (.) as the decimal separator and comma (,) as the thousands separator. Add additional zeros to show more decimal places.

2. Configure other image properties.
3. Save the screen.
4. Run the screen to test your configuration.

The Custom Context Menu Configuration dialog box is where you configure any custom context menu items that will appear in the right-click context menu for the screen or control. Each custom context menu option will call an event into script so that you can customize screen or control behavior. The custom context menu options will appear at the bottom of the fixed context menu options, separated by a line.

Perform the following steps to configure a custom context menu.

Sample Custom Context Menu Configuration dialog box

1. Click to open Custom Context Menu Configuration dialog box.
2. Click Add to add a menu item.
3. To add child menu items, select the parent menu item and click Add. You can add multiple nested menu items if desired.
4. Click to expand the menu items.
5. For each menu item click on <New> to reveal the properties:
   1. Title — The Title property specifies the menu name to be displayed in the runtime context menu.
   2. Is separator — The Is separator check box indicates whether this menu item will be a separator line in the menu at runtime. Once saved the separator has no configuration and no children. Separators do not have event IDs. Any event ID on a menu item when it’s converted to a separator is deleted. You can give it a title of 'Separator" or "----------" if desired.
   3. Script event ID — The Script event ID specifies the event ID that will be called when the menu item is selected from the runtime right-click context menu. The event ID is passed in as a parameter into the Custom Context Menu Action event, along with other relevant information in the context of the click, for example, facility or point tag, as appropriate.
6. Menu items can be easily reordered by dragging and dropping an item to a new location in the list.
7. Or click (Delete this item and its children) to remove a selected menu item as necessary.
8. Once the context menu items are configured, click OK to save.
9. Or click Cancel to abort and close the Custom Context Menu Configuration dialog box.

The source of the image displayed in the image control can be explicitly configured or it can be dynamically changed depending on the point state of the associated point. Sizing options are also provided to prevent image distortion when the control is resized.

1. Find the Image properties to enable and configure the image properties.

1. Enabled — The Enabled check box indicates whether the image on the control is enabled. The default value is True.
2. Image file path —

   This property specifies the path to the file, image file, video file, object file, or screen file. Depending on the selection in the source property the type of path is different. Click to access either the:

   • Select File dialog box —To access an APPS or BSS folder
   • Open File dialog box — To access a local or network file-system folder

   Note: If no image is specified or the image is missing, a missing image icon () is displayed in both design and run mode.

   Note: Point data and/or text will display in run mode, even if the no image is specified and the missing image icon () is displayed.

3. Image file source —

   This property specifies the source of the file, object file, screen file, image file, or video file. Options include:

   • BSS — Indicates that the file is stored in an APPS or BSS folder
   • Local — Indicates that the file is stored in a local or network file-system folder.
4. Image height — The read-only Image height property specifies the height of the image used in the control if no point-state-aware image is displayed.
5. Image width — The read-only Image width property specifies the width of the source image used in the control if no point-state-aware image is displayed.
6. Images — The Image Selection dialog box is where you configure CygNet-aware images that will dynamically change based on the point state of the associated point. The point state preference is configured in the Resolution mode property. A default image is displayed if you configure point-state-aware images and no matching state exists. Click to open the Image Selection dialog box.

   Sample Image Selection dialog box

   1. Click to open Image Selection dialog box.
   2. Select the appropriate Point scheme. The point scheme defines the point types, point alarms, point statuses, and default colors for a CygNet domain.
   3. Select the Point type to access the point states on the right. The point types are configured for the selected point scheme for your CygNet system. The default CygNet Standard Point Scheme has eight point types: Analog Input & Analog Output, Digital Input & Digital Output, Enumeration Input & Enumeration Output, and String Input & String Output.
   4. Click on the Point state for which you want to configure an image to use when the point state changes in the control. Point state is the highest precedented state for a point record as defined for each point scheme. The point state for a point record is based on 48 System, Configuration, and User status bits, which are associated with the four point types (Analog, Digital, String, Enumeration). A point record may contain up to 48 status bits, which are used to provide point status information about the point record in a CVS and the ELSALM. A point can be in multiple states at the same time, for example, in High Warning and High Alarm; however, the state defined to be the most severe is the one that is used for the point state (i.e., High Alarm, in this case).
   5. For each point state perform the following:
      1. Image — The Image property indicates the file path and file name of the image that will be substituted when the point state changes to the selected point state. Browse and select the desired image file. Click to select a path and file from the Open / Open File / Select File dialog box, where you can access: A thumbnail of the selected image, and its dimensions are displayed for each point state.
      2. Repeat for each point state.
   6. To remove an image, delete the path in the Image field.
   7. Once the images are configured, click OK to save.
   8. Or click Cancel to abort and close the Image Selection dialog box.

   Note: If no image is specified or the image is missing, a missing image icon () is displayed in both design and run mode.

5. Resolution mode —

   The Resolution mode property determines how a point's status should be used to select images to display. The image will display based on the point state or the alarm condition of the associated point. The point state of the associated point is evaluated to determine which image to display. Options include:

   • Point state — all possible point states are included
   • Alarm condition — only point states marked explicitly as an alarm condition in the CVSMetadata are included (point states with the alarm condition attribute set to "true")

   The default option is Point state. Point-state-aware images are configured in the Images property.

   Additional Resources

   For more information about Point State and Alarm Condition, see Points > Points Overview > Point State and Alarm Condition.

6. Size mode —

   The Size mode property specifies the method used to size the image so it can scale without distortion. Options include:

   • Stretch — Resizes the image to fill the entire area, while maintaining its native aspect ratio.
   • Auto — Displays the image using its raw size. If the image is too big to fit within the boundaries of the area, sizing follows the Stretch behavior.

   The default value is Auto.

If the Image height and/or Image width values exceed the boundaries of the Image control, the image uses the selected Size mode behavior and is uniformly stretched to fit the control's boundaries. If the Image height and/or Image width values are smaller than the boundaries of the Image control, the image will be centered within the control's boundaries.

2. Configure other image properties.
3. Save the screen.
4. Run the screen to test your configuration.

1. Find the Font properties to configure the font size and text properties for the control:

1. Font size — The Font size property specifies the font size of the text on the control or map visual.

2. Text style — The Text style property specifies the style to use for the text that appears on the control or map visual. Options include: Normal, Italic, or Oblique. The default value is Normal.
3. Text weight — The Text weight property specifies the weight to use for the text that appears on the control or map visual. Options are: Normal or Bold. The default value is Normal.

2. Configure other control properties as necessary.
3. Save the screen.
4. Run the screen to test your configuration.

1. Find the Tooltip properties and configure the content of the tooltip for this control:

1. Tooltip —

   The Tooltip property specifies the text that will appear on the tooltip. The text display a static text string, such as a label, legend, tooltip, or a dynamic text string based on point or facility attributes. Dynamic text is built using tokens, which can represent real-time CVS point properties, point configuration properties, and facility properties. In run mode, the tokens are replaced with the attribute's value. Click to configure the static text and/or property tokens using the CygNet Property String dialog box. Note: A tooltip can be single-line or multi-line. Type any text, select tokens, and press Enter to separate the lines. If more than five lines are entered, a scroll bar will appear in design mode. The scroll bar does not display in run mode. Also see the Tooltip Opening event for controls that support tooltips.

   Multi-line tooltip example

2. Tooltip enabled — The Tooltip enabled property indicates whether to display a tooltip when the mouse hovers over the control or map visual.
3. Tooltip mode —

The Tooltip mode property specifies how the tooltip will be displayed. Options include:

• Text — The tooltip displays as plain and/or tokenized text defined in the Tooltip property, using resolved point and facility properties.
• Object — The tooltip displays as a Canvas object, passing in the facility tag of the control.
• Script — A TooltipOpening event is fired to allow script to create a custom tooltip.

The default value is Text.

4. Tooltip object path — The Tooltip object path property specifies the path used for the tooltip when Object mode is selected. Click to select a path and file from the Open / Open File / Select File dialog box, where you can access:
