Find and Open Pages Within an Application

In VTScada, "screens" and "pages" refer to the same concept: an on-screen display of information about your system.

Knowing how to find and open pages is a necessary skill in order to use any application. Even if your application was designed to fit on one page, VTScada itself provides a set of pages for alarm monitoring, creating reports, writing operator notes, and other tasks. Typically though, developers create many pages and design the navigation between those pages as seems best. You are unlikely to find two applications with the same, or even a similar, page layout.

There are usually several ways to find and open a page. Choices for the user will depend on the application design, what security privileges are granted, or both.

 

The Menu System. There are two versions of this...

The List Page Menu

The List Page Menu and the Tile Page Menu will always have exactly the same content, organized the same way. Use whichever you prefer.

If security privileges were created to protect pages within your application, those privileges also apply to menus. You might not see all pages if your security rights do not include the privilege required for a given page. If you are certain that a certain page exists but you do not see it in the menu then at least one of two things is true:

  1. That page is protected by a privilege that you don't have.
  2. That page was not added to the menu system. There may be other ways to navigate to it, such as via page buttons.

The List Page Menu is accessible by selecting the icon in the bottom left corner of application window.

 

To open the list version of the Page Menu, select the menu button at the bottom-left corner of the screen (left image), or the top-left (above). Placement of the List Page Menu icon can be set in the Display Tab of the Edit Properties Page under "Task Bar Contents" and "Title Bar Contents" within the application configuration dialog.

The list version of the menu. Your application will have different entries.

The menu will open upwards to the height of the page, displaying the accessible menu contents. Selecting the 2 x 2 grid icon in the top-right corner will return you to the tile version.

Selecting a menu item with a chevron and folder icon to its left will expand it downwards, revealing a sub-list of further selectable folders or page menu items. Left-clicking on a non-folder menu item will open its corresponding page, right-clicking will open the page as a pop-up. Each non-folder menu item will be displayed by name, with an icon to the left, conveying the page's purpose at a glance.

When it has focus, the list menu can be traversed with the keyboard. Open highlighted pages or toggle folders by pressing the enter key. Folders can also be opened by hitting the right arrow key or the '+' key, and closed by hitting the left key or '-' key. Selecting 'page up' brings focus to the top list item and selecting 'page down' brings it to the bottom.

As of VTScada version 12.3, the list version of the page menu includes a 'Recent Pages' section and a Search Bar.

Between the menu and the search bar is 'Recent Pages,' a list of pages navigated to in the recent history of the current user's activity. Select a page in the list to navigate to it, or the 'Recent Pages' heading to collapse or expand it.

Type a search criteriea in the field at the top of the page menu. Press enter or click on the magnifying glass to the left of the field to search, or click the X at the right to clear the field.

The list version of the page menu also includes a search bar. Type a search phrase into the field at the top of the menu and hit 'enter' or click on the magnifying glass icon to filter out available menu items inconsistent with the search criteria. Folders will be the first results displayed, followed by applicable pages in alphabetical order. Select the 'X' on the right of the search field to clear it and restore the page list menu to its default state.

Navigate using the list version of the page menu

  1. Click the list menu button at the bottom left corner of the VTScada application's screen.
  2. Click on Alarms, Reports and Diagnostics to open that folder.
  3. Click on the Alarms page entry.
    The Alarm page will open, and the menu will close.
  4. Reopen the menu.
  5. Click to open the Remote Sites folder.
  6. Open the Sites page.
  7. Now, try navigating to pages in the menu using the keyboard. When it has focus, the list menu can be traversed with arrow keys, and the enter key can open highlighted pages or toggle highlighted folders.
  8. Returning to the list menu button, open the Sample Pages folder, then Dashboard A.

The page version of the menu. Your application will have different entries.

The Page Menu

To open the page version of the page menu, either click the four rectangles at the bottom-left corner of the screen,

select the same icon from the List Page Menu,

The Tile Page Menu is accessible by selecting the icon in the top-right corner of the List Page Menu.

or click the VTScada logo at the top of the screen.

The Page Menu also counts as a page, in that you can navigate to it. The menu will fill the screen with previews of the pages. Where sub-menus appear as drop-down menus in the list version, here they look like folders.

Click a folder to open it.

The ability to show a live view depends on how many tiles there are and the size of the pages shown on those tiles relative to the screen. If the complexity requires excessive workstation resources, then a static "snapshot" view is shown instead. Snapshot views are indicated by a camera image:

Properties control the threshold between live and cached views.
PageSnapshotCacheThresholdCount, PageSnapshotCacheThresholdPct, and PageSnapshotsMaxInMemory.

Navigate using the page version of the page menu

  1. Click the Page Menu Tiles button at the bottom left corner of the screen. (The 2x2 grid.)
  2. Click on Alarms, Reports and Diagnostics to open that folder.
  3. Click on the Alarms page entry.
    The Alarm page will open, and the menu will close.
  4. Reopen the page menu by clicking the VTScada logo at the top left of the screen.
  5. Click to open the Remote Sites folder.
  6. Open the Sites page.

Navigate with Hotboxes and Page Buttons

Most pages will include links to other pages. These will be either a hotbox or a page button as shown.

A hotbox.

A page button.

The hotbox will not be visible until you hover the pointer over it. Then, it will change color (usually yellow) to let you know that you've found it and can click.

A page button is always visible, and therefore much easier to find. Just click to open the target page.

Pin useful pages.

Left to right, the task bar contains buttons for the page list menu, page tile menu, navigational arrows (if needed), pinned and current pages, and a date & time display.

You can create your own navigational shortcuts in the application. When any full-screen page is open, the navigation bar at the bottom of the screen will show it. Within that box, you can right-click the page name and select 'Pin' to save that page in the list.

You must have access to the task bar beneath a page, therefore pinning is (generally) for full-screen pages.

The ability to choose which pages to pin is all yours. The list is unique to your account; nobody can pin a page for you, and you cannot pin pages for anyone else. Pins set before security is enabled are lost after security is enabled.

Pinning a page.

Removing the pinned Overview page

Navigate to another page and the one you pinned will always be available. You can remove a pinned page from the navigation bar by right-clicking on the shortcut and selecting 'Unpin' from the context menu.

You can pin as many pages as you want, but it's best to limit the number so that they fit on the screen with full titles displayed.

  1. Navigate to the Alarms page.
  2. Right-click on the button with the page name at the bottom and select 'Pin' from the context menu.
  3. Navigate to the Historical Data Viewer (HDV) page.
  4. Note that the link to the Alarm page remains in the taskbar.
  5. Pin the HDV page.
  6. Use the pinned links to navigate between the two pages.
  7. Switch the positions of the taskbar shortcuts using the controls in the context menu.
  8. Unpin the HDV page by right-clicking on the shortcut and selecting 'Unpin.'

Navigate with Forward and Back Buttons

See a list of selectable pages to revisit by right clicking on the 'Previous' arrow.

You must right-click or click and hold the Previous or Next button for two or three
                  sseconds to get the list of recently-visited pages.

At the top-left of the screen are two buttons: Previous and Next. You can use the Previous button to step back through the pages you visited earlier. After stepping back through a few pages, you can use the Next button to step forward again.

Right-click on either button to view the History Menu, a list of visited pages with your current page highlighted, ordered latest at the top and oldest towards the bottom. You can select any page in the list to revisit, which is probably faster to do than clicking through the list one page at a time.

Open a Page in a New Window

Many pages can be opened either full-screen, or as pop-ups, or in some cases, both. This might be useful if you want to view the Alarm page without leaving whatever page you are currently looking at.

For example, if you are currently viewing the Overview page, and you want to see the Alarm page as well, right-click on the alarm symbol at the top of the screen. The page opens in a new pop-up window.

Middle-click (commonly achieved by pressing the scroll wheel) on pages pinned to the task bar at the bottom to open them as pop-ups. Right-click on pages in the Title bar or List Page Menu to do the same. Right click on pages in the Page Tile Menu to open a context menu from which 'Open as Popup' is an available option.

The various pages of your application (that is, pages other than those built into VTScada) may or may not work the same way, depending on how they were configured.

Limits on Pop-Up Pages

Some applications are designed to limit the number of pop-up pages that will open. If this describes your application, then you might see a message similar to the following.

Eight is the default pop-up page limit.

Or, extra windows might be denied.
