• The OPC Foundation has implemented the OPC UA standard in several programming 
languages: Stacks for .NET, ANSI C and Java are available, but the stacks for ANSI C and Java 
are no longer maintained. The OPC Foundation oers the .NET stack as well as sample 
programs as open source software (https://github.com/opcfoundation).
Several companies oer Software Development Kits (SDK). These development packages 
contain the stacks of the OPC Foundation and other functions that facilitate the development 
of solutions. Advantage of using SDKs:
– Support from the supplier
– Tested software
– Exhaustive documentation
– Clear licensing terms (important for reselling solutions)
