Advantages of OPC-UAC

• Simple - The use of OPC-UAC library is definitely simpler, especially in the configuration phase where the software allows browsing of the items supplied by the OPC Servers connected in the network.
• Flexible - Thanks to use of the standard OPC technology, OPC-UAC allows your C/C++, C#, VB projects to communicate with a wide range of peripherals of different companies and in various models.

The OPC-UAC .NET component from Automa provides a basic and very simple interface for reading, writing and monitoring operations of changes in values in variable items.

Connections, items and subscriptions are pre-configured in a file with a configuration tool which manages server discovery and item browsing.

The communication task is carried out in an automatic and transparent way. Items are identified through an alias name which hides the item specific node Id.
