We have released a new minor version of Prosys Sentrol OPC UA & Classic SDK for Delphi and C++ Builder.

The release includes important improvements to the OPC UA implementation, which is based on version 1.04.10 of the OPC UA Stack and Information Model (Nodeset), which affect especially the OPC UA Server side.

This version adds major OPC UA functionality to the server side implementation, including instantiation of objects and variables based on the respective type definitions. This enables creating complete object structures with components and properties.

With the help of instantiation it became also possible to support all standard event and alarm types.

The release also adds support for OPC UA Historical Access on the server side, in addition to the respective functionality that was already available on the client side. This is demonstrated by the sample MyHistorian that is added to the UaSampleServer project (and the respective MyCppHistorian for UaCppSampleServer).

There are also important security fixes in the release. These affect especially the OPC UA Stack and OpenSSL components that the OPC UA SDK is using, but also the Windows DCOM Server Security Feature Bypass issue is now fixed by default.

As usual, we recommend all customers to update to this version.

See the Release Notes for more details about the changes and fixed issues.
