Visual OPC .NET Trending
Visual OPC .NET offers a very powerful trend control. There are several
features that make this control desirable by many developers.
Easy Configuration
Like all other Visual OPC .NET components, the trend control can be completely
configured from the Visual Studio designer. However, it's fully documented
object model is designed so it can be programmatically configured as well.
Internal Archiving Service
The trend control can be configured to archive OPC data. The archived data can
be configured to have both a lease duration and retiring age. The lease
duration may be set to continue archiving data even after the control has been
closed. Thus, if the control is closed and reopened, all data (even the data
received while the control was closed) is trended on the control. After data
has reached the retiring age, it is removed from the archiving system to limit
the growth of the data store.
Runtime Navigation
A configurable runtime navigation panel can be added to the trend control.
This allows your end user to select the time period dislayed by the trend
during runtime.
Selectable Zoom
Any area of the trending region may be selected to which the user may choose
to zoom. The selection uses alpha blending that gives the control a
contemporary look.
Fully documented
Just like the rest of the Visual OPC .NET components, the trend control is
fully documented. The documentation integrates with the Visual Studio Help.
