What is an OPC .NET Wrapper ?

• Explaining the components and API of .Net wrappers

64-bit Operation
.NET applications are by default compiled to run automatically in 64-bit mode on 64-bit systems. However, currently only the Advosol OPC .NET wrappers are capable of working in 64-bit mode. With other wrapper products the .NET applications need to be compiled to only run in 32-bit mode and cannot take advantage of the capabilities of 64-bit systems.

OPC Standards are explained and compared:

.NET3 (Windows Communication Foundation)
.NET3 is the default on Windows Vista and can be installed on other Windows versions.
The communication features of .NET3 (WCF) are generalized and enhanced. Web services, Remoting and other Microsoft communication features are combined into one application interface.
.NET3 Web Services can be configured to use different communication protocols such as basicHTTP for .NET2 web services compatibility, TCP for high performance, secure HTTP and others.
The Advosol XML DA client and server products are provided in a version for .NET2 and one for .NET3. XML DA with .NET3 offers many of the features that will be available with OPC UA.
