The OPC AE .NET Server Toolkit is an Alarm & Events Add-in for the DANSrv OPC DA .Net Server Toolkit, making the server compliant with the OPC specifications DA2, DA3 and AE.
Event Sources can be OPC DA items or any othe signal source. The toolkit is flexible and does not restrict the user.
All application specific server code is in a .NET assembly that can be coded in C#, VB.NET or with any .NET compiler. The generic server handles the .NET wrapping of client calls and callbacks. The user can implement a simple interface with convenient .Net data types.
The AE option is available for the DANSrv Standared Edition and Professional Edition, making the toolkit economical for simple applications and powerful enough for highly complex applications.
Why use .NET for OPC Servers ?
.NET is widely used for desktop and web service applications. VB.Net and C# have great advantages and are the preferred tools of many software developers. DANSrv Toolkit based OPC server development is not much different from desktop applications development. No DCOM issues have to be handled. The OPC server can interface a database or e.g. use TCP/IP to communicate with a device. The database access or the TCP/IP communication is what has to be implemented in the customization assembly and this is well supported by .NET.
Serial device communication or direct I/O port access can alse easily be handled with .Net. Serial I/O and Port I/O classes are provided and even more sophisticated implementations of such classes are available as software component products from multiple vendors. |
