About the Rdbms Point Device Extension

Starting with NiagaraAX-3.4, the Rdbms Point Device Extension is available as part of most RdbmsNetwork driver devices. As described in Chapter 2 About the RdbmsNetwork, the RdbmsNetwork and RdbmsNetwork device drivers resemble the typical "field bus" type drivers in that they are represented in WorkbenchAX as "devices". You can view all devices that are under the RdbmsNetwork in a Device Manager view, or in the nav tree, with each device that is installed under the network representing an individual database type and connection.

 
NOTE: To use this feature, you must set the Sql Scheme property to true (this property is located on the RdbmsNetwork Driver Device property sheet.
 

The Rdbms Point Device Extension provides point import capability for the various relational database drivers using methods and views that are similar to other proxy point driver views. Using this point device extension to import points, you can represent relational database cell values as proxy points in NiagaraAX, as shown below.

The Rdbms Point Device Extension Graphic (RdbmsPointDeviceExt) may contain one or more Rdbms Point Query Graphic properties (depending on how many you add). Individual points are then added under each individual Rdbms Point Query property using the Discover and Add process available in the Rdbms Point Query Manager view. Rdbms Points are always organized under their parent Rdbms Point Query in the nav tree and are also displayed in the Database pane of the Rdbms Point Query Manager view.
