Data Binding to Widgets

Use these options to provide input values to your queries in a quick and simple manner.

Attention: In case you modified the data source alias (machine name), then all references to the data source (Historian or OPC UA) server are lost. You will have to browse and select all over again to build input queries.

Tag Browser

A list of out-of-the-box (OOTB) queries of 'Extension' type are available with the tag browser.

  1. Select the OOTB query that you want to apply to the widget.
  2. Browse the data source and select tags.
  3. Drag and drop the query on your widgets. This automatically populates the data fields for the query under PAGE DATA.
  4. Save the page with the default data from the query, (OR) modify the data fields to your requirement.

Inputs

Queries have input values. On drag and drop from tag browser, these inputs are bound to the widget, and appear under PAGE DATA.

Each input has these options that are populated with default values as per the query:
  • Manual: Allows to use a variety of components to provide manual values for query inputs - text, number, date, time, datetime, browser, combo box, and boolean.

  • Global
  • UI
Note: At any point in time, ensure that only one binding exists for the query inputs. For example, there should be no manual or global binding if you have already bound the query input to UI through a widget or plugin. To remove a binding from the query input, select the unlink icon next to the binding.

Link to Access the Query

If you changed the Asset Context for the page, access a direct link to the query to update or modify it.

On selecting the widget, a link to the associated query appears under the widget properties. Select the link to directly jump to the query on the PAGE DATA tab.

Drag and Drop Data

You can drag and drop the data from selected tags or properties onto the widgets. You can also select Add to add the query to the page.
