OPC HDA Programming Made Easy with OPC HDA Client Toolkit !
Integration Objects’ OPC HDA Client Toolkit is an OPC toolkit that facilitates the integration of an OPC HDA client within your VB or C++ application. It combines an OPC HDA client API, Visual Basic wrapper and API for C++ . In fact, it implements all of the required and optional interfaces for OPC Historical Data Access specifications.
This OPC toolkit ensures simplicity and flexibility of OPC HDA client application development within VB and C++ environment.
The OPC HDA Client Toolkit facilitates accessing data points from any OPC HDA server, reading raw and processed historical data. Indeed, it effectively helps developers overcome the COM calls details and the OPC HDA standard specification complexities. Moreover, it allows users to update their historical data records.
