OPC for Delphi
With one source write OPC UA clients for
As a Pascal developer, we would like to offer you the opportunity to work with the OPC standard in the familiar Embarcadero (Codegear, Borland) Delphi and Lazarus environment, we have developed a OPC software toolkit (SDK, Framework, Toolbox) supporting the most common OPC interfaces and protocols: OPC UA (Unified Architecture), XML DA & classic OPC (Data Access DA, Alarms & Events AE and Historical Data Access HDA).
Our dOPC Client Toolkit for Delphi is probably one of the most used OPC component collection for Delphi worldwide.
Our powerful dOPC Toolkit allows you to build OPC client applications with just a few mouse clicks. E.g. dOPC includes a GUI component that allows you to bind OPC item values directly to properties of visual components, such as labels or edit boxes.
If you want to create high-end OPC client applications in a fast and professional way with the highest performance, then our dOPC Client Toolkit is the right solution for you!
We encourage you to download our free trial version, which is fully functional and includes a comprehensive help file and over 30 demo and example programs (with source code).
In addition, there is a huge variety of good reasons why you should purchase our OPC Framework:
