Bind Your Data to Plug-ins

This topic describes the available options to configure source and target data.

In Operations Hub, you can select from the following options to pass values to the plug-in from your data source. You can also specify a target data source to receive data from a plug-in.
On the plug-in's details panel, you can choose the options from a drop-down menu.

Query

When using a query to configure source data, select at least one output field.
Alias Option to enter a temporary name for the query's output field.
Output Field Lists all the data fields available in the selected query.

On executing the query, data is retrieved from the data source for the selected output fields.

For example, a weather application might use a query to retrieve the current temperature, humidity, and precipitation levels for a particular location, and use these fields as the basis for its output.
+Add To include additional query output fields, select this option.
+Add All If you want to include all the query output fields, then select this option.
When using a query to configure target data, select at least one input field.
Input Field Lists all the data fields available in the selected query.

The selected input fields are used to execute the query to retrieve data.

For example, a weather application might include input fields where you can specify the location, temperature unit, or forecast duration.
+Add To include additional query input fields, select this option.

Global

This option allows you to select a global variable to configure source data and target data.

Manual

This option allows you to manually enter the values for the plug-in. You can also access enhanced preview of the real-time data within the page designer. The plug-in preview is the same as the result that appears in the end application.

Formula

Select Add Formula to create a formula that returns values for the plug-in.

Fetch Data Property

This option is view-only. It applies when you drag-and-drop tag data on a plug-in. The drag-and-drop action automatically fetches the data from the data source, and updates values to a list of applicable properties.

On drag-and-drop, the Fetch Data Property label appears for:
  • Minimum and Maximum scale values
  • Engineering unit
  • Data range values

In case you drag-and-drop multiple tags on a plug-in, then values fetched from the first tag are applicable to the above listed properties.
