NEW! OPC UA Client & Server Components

Reliable and secure data communication based on OPC Unified Architecture (OPC UA, IEC 62541) is essential for system integration in Industrial Internet of Things (IIoT) and Industry 4.0 solutions.

Prosys Sentrol OPC UA SDK for Delphi builds on the successful legacy of Prosys Sentrol OPC Classic SDK.

OPC UA & Classic Client Development

Prosys Sentrol enables easy client side configuration of data flow from OPC servers to user interfaces, databases and other systems. Still, with the true object oriented components, this OPC toolkit means you are in full control over your application. Whether you need to create a power application or just a simple tool that leverage the availability of real data in various devices, you will have a perfect set of flexible, easy to use components.

NOTE: The OPC UA Client does not yet connect with the rest of the Prosys Sentrol components that enable fast configuration of user interfaces.

OPC UA & Classic Server Development

Prosys Sentrol includes an interoperability tested OPC server implementation for both OPC UA and Classic development. Adding OPC server into your application or hardware product offering is now possible with minimum effort. This is truly the number #1 OPC toolkit for OPC server development in Delphi & C++Builder.

Interoperability tested OPC Toolkit

The software components of Prosys Sentrol take care of numerous details required by reliable, interoperable OPC client and OPC server applications. This allows you to concentrate on the application design, instead of communication details, which will reduce the development time and costs. The reliability and usability of our OPC toolkit has been verified in various 24/7 installations that have been running over 10 years.

The new OPC UA functionality relies on the open source OPC UA Stack developed and maintained by the OPC Foundation. It is the most popular stack implementation and has been tested and verified for interoperability and reliability in a great number of real-world applications for over 10 years.
