What's New in Visual OPC .NET 3.0

Support for Visual Studio 2005

Visual OPC .NET supports Visual Studio 2005 and v2.0 of the .NET Framework while remaining compatible with Visual Studio 2003 and .NET Framework v1.1.

Improved Threading Support

A new property enables you to have all OPC callbacks marshalled to the parent form's thread. Therefore, a call to Form.Invoke to sychronize threading is no longer required.

What's New in Visual OPC .NET 2.0

Trending! Visual OPC .NET 2.0 offers the very extensive trend control shown below. It can be added to any Windows Form and can be configured without a line of code.

Multiple pens	The trend control will handle any number of pens. Each pen is attached to an OPC DA item.
Multiple server support	The trend control can collect data from both OPCDA and OPCHDA servers simultaneously.
Internal archiving service	The trend includes an internal archiving service that can be configured to log the data even after the trend has closed. The archiver is OPCHDA compliant and may be accessed by other OPCHDA clients.
Runtime navigation controls	Your end user can navigate where he wishes to view the data with the navigation controls that are included with the trend control. These controls are optional and may be left off the trend control if desired.
Runtime property pages	The user can access the trends properties during runtime. He/she may change the properties that you designate as modifiable.
Runtime zooming	Zooming is as simple as selecting the area to zoom to and clicking zoom. Zooming back is as simple as clicking 'Zoom back'.
Tooltip coordinates	View the coordinates of the cursor in the tooltip.
Legend	A configurable legend is included with the trend.
Visual Studio designer support	The entire trend control may be configured by the Visual Studio designer.
