The application need to install a uaPlusMain.OnCreateApplicationNodeHandlers event handler and call this method from the event handler.
The node manager implementation must be derived from the BaseNodeManager class.
Syntax
| Visual Basic (Declaration) | |
|---|---|
Public Sub AddApplicationNodeManager( _ ByVal nodeMgr As BaseNodeManager _ ) | |
| C# | |
|---|---|
public void AddApplicationNodeManager( BaseNodeManager nodeMgr ) | |
Parameters
- nodeMgr
- Instance of the application specific node handler.
Remarks
With an application specific node handler the application specific features can be implemented on UA node manager level. The interface of the plug-in DLLs corresponds to the Classic OPC DA/HDA/AE interfaces. These are simpler but don't support all UA features. Used with the plug-in DLLs uaPLUS provides easy transition to UA and a simple way to implement basic UA severs.
With application specific node managers there are no other interfaces involved but the developer needs knowledge of the rather complex UA specification.
