In order to log values directly from a Visual Studio application you will need to implement the .NET Data Connector as demonstrated in the WinForm Example Code under FormDataLogging.

You can log values just as if the values were from an OPC Server, just setup Tags with a data source of Value, the desired data type, and then from your Visual Studio application use the WriteTags method of the OPC Systems Data Connector component.

If you also include TimeStamps array in the WriteTags method the service will use the TimeStamps you write instead of the CPU clock time when writing values to the database.

You can also setup data logging groups to be triggered based on event and assign a Boolean Tag as the Trigger Tag. From your Visual Studio application your code in simple form would look like the following:

The result in the database for this one WriteTags method would be 3 records:
