OPC .NET Client SDK

Integration Objects´ OPC .NET Client SDK is the fruit of one year of labor and focus that was used to create a powerful, highly optimized toolkit that integrates the three major OPC Specifications in their latest versions. In fact, this toolkit is fully compliant with OPC DA (1.0a/2.05), OPC HDA (1.10/1.20) and OPC AE (1.10).

The OPC .NET Client SDK is a Windows DLL (Dynamic Link Library) that handles all COM and OPC details needed to interface with OPC servers. It is a tool for fast and easy creation of .NET OPC clients. Using this DLL, .NET custom applications will be able to access data from any OPC server (DA, HDA and AE) without having to be concerned with the details of the OPC standard.
