Additionally, you can use ".. Ignition provides a great deal of flexibility for Tag addressing since Tag paths and Tag properties are string-based. The underlying strings that compose a valid Tag path can be assembled from many different parts in with the eventual construction resulting in a valid Tag path.
The following scripting demonstrates this concept. Suppose there was a Tag path to a level indicator in a tank. But suppose that there was more than just Tank 1 and instead there was Tank 2, Tank 3, Tank 4, etc.
Dynamically changing the Tag paths is simple because Ignition's Tag paths are string representations. The following takes the tank number and inserts it into a new Tag path. The tankNumber variable changes the eventual creation of the tagPath.
Using this method in scripting or in an expression binding will look slightly different. Tags have a built-in "this" keyword, that can be used as a reference to the tag. The keyword is useful in cases where an expression is being configured on a tag property, and you want to reference the value of another property.
The "this" keyword is also available for use on expressions on alarms. However when used like this, the keyword still refers to the Tag, not the alarm. Thus, " this. Related Topics Then you can drag components into the container.
Notice that the properties are now in the Flex container. Once you create your view, the next step is to set up your navigation using Pages. The Container is a special kind of component. True to its namesake, a container is a component that contains other components. Within every created view is a root container that cannot be removed or renamed.
The dimensions of this container will span the entirety of the view. If you wish to change the container type for a view, you'll need to create a new view.
In the Project Browser, next to the root there will be an icon representing the type of container it is. There are types used in Perspective:. In Perspective containers enable you to have a layout strategy to control the size and shape of any housed components.
The layout strategy defines how the container displays each of its child components in the view. There are a variety of container types that support different layout strategies. A simple strategy to accommodate radically different screen sizes is to design a view or container in several different ways, with each design tailored to different screen sizes. The column and breakpoint types accommodate this design strategy, by picking one of two or three different containers to open based on a specific range of pixel widths for the session.
The term "Breakpoint" is a common piece of terminology used to describe this design - it is the width in pixels at which the Perspective session decides to use one container over another. The Column container is a good option when you want to have the same components and views for every screen size, and simply want to lay them out differently at smaller or larger sizes. Selecting one of the sizes will give you the opportunity to configure components ' layouts for that size.
For instance, selecting Small will allow you to position the components , embedded views, and containers in your view in a way that makes sense for mobile devices, since most mobile phones will sport a session width less than pixels.
Rearranging the same components in the Medium container would provide a nice design for larger smartphones, many tablets, and some desktops, while the Large configuration will yield a container that works for high-resolution monitors and televisions.
The Column container is an easy-to-use option for simple layouts, but more involved ones might require more customization. Perhaps you want desktop, tablet, and mobile sessions to look and feel quite different, or you want to use one of Perspective's new navigation components , but only for mobile devices.
Even in these circumstances, you don't have to design several sets of pages, or even several projects, to all implement the same task. Breakpoint containers enable you to design views tuned to different screen widths, but unlike a column container, where a single view can take on three forms, in a breakpoint container you actually specify two distinct views, each with their own components and functionality.
Breakpoint containers are thus the more flexible option; as long as your "mobile" views share an essentially similar framework with your "larger" views, you will be able to develop the views concurrently, and the Perspective session will decide at runtime which set of views to use. You can think of a breakpoint container as bundling together two views that serve a similar purpose, but are tailored to different screen sizes.
Sometimes you may want to compartmentalize a view or container in a particular way, either to modify the component layout or organize the structure of your components in the Project Browser. Containers are a special kind of component that can contain children and can also be nested, which supports multiple layout strategies.
This means that application designers can nest containers inside of other containers to compose layout strategies that are more complex and capable than any one container can provide. You might want to have nested containers to create a more complex layout. For example, you could have a Tab container that has several tabs with very different information in each tab.
In one tab, you might have a table that looks great on a desktop but terrible on a phone. Using a Breakpoint container inside of only one tab in a Tab container will allow you to make a more useful mobile experience while still showing a table on a desktop computer. Sometimes you'll want to make a very simple view for use inside a higher-level setting, like a Carousel or a Breakpoint container.
If you only need a view to hold a single component that fills the container, you can:. Sometimes you'll need to repeat the same container a specific number of times in a row or column, or you want to create a grid of child containers. For this purpose, you can:. Ignition User Manual 8. Browse pages. Copy Page Tree. Jira links. Views Perspective Views are unique in that they can act as both a top level screen taking up a whole page in your session or a component embedded in another view.
Embedded Views An Embedded View is an instance of a view that is used as a component within another view. You'll notice when you nest a view inside another that the Embedded View component has some properties that are distinct from those of the view you're nesting: path is the path to the view you wish to embed.
To access the properties for a view, select the view in the Project Browser, for example: The property types will be displayed in the Perspective Property Editor. Anatomy of a View Watch the Video. Docked Views in Perspective Watch the Video. View Properties Views, like components, have properties. The view properties have three categories: Props - Properties used to configure the component's visual appearance, behavior, and data.
