Configure connections, elements and subscriptions.

Virtualize elements by assigning them an alias name that hides their relationship with the server. With the configuration tool you discover the servers and set up connections by selecting the desired endpoint, browse the server namespace to select the items you are interested in and organize them into subscriptions to define your update and notification strategy. The configuration allows the relationship with the servers to be hidden and virtualized.

One call is enough to bring up the whole communication process and very few others to read, write and receive notifications about variables values changes. Reconnections are managed automatically and transparently. Thanks to .NET and Win32 APIs interfaces OPC-UAC can be easily integrated in different types of applications. Supplied demo projects for VC2019 and VC2010 show an usage example for both interfaces.
