Bql Query Builder

You can use the Bql Query Builder to create and execute a discovery query for finding various types of system entities, including components, points, video elements, and other objects. For example, you can use a BQL query to locate points and video elements that you can bind to Px widgets for visualization.

The Bql Query Builder provides a means for you to find objects and filter them in a single discovery process. Starting with Niagara 4.12, the Bql Query Builder window is also available when you are connected to your station through a web browser.
