Client Development SDK for OPC DA
The OPC DA Client SDK .NET offers a fast and easy access to the OPC Classic Client technology. Develop OPC compliant DA Clients with C#/VB.NET for the .NET 4.7.2 framework.
The OPC DA Client SDK .NET API defines classes which can be used to implement an OPC client capable to access OPC servers supporting different specifications with the same API. These classes manage client side state information; provide higher level abstractions for OPC tasks such as managing sessions and subscriptions or saving and restoring connection information for later use. The lower level API’s for OPC DA defines classes which can be used to access OPC specification specific methods and properties.
