The Virtual Data Source is a data source without any connection to an external or physical system. It exists entirely within the system's own memory space. The data it produces is either random, or deterministic depending on how you configure the points.

Virtual data sources can be useful in a number of ways:

The data source configuration is simple. It requires only a name, and the period of time between each data update. For example, if you choose "2 minutes", then every two minutes the algorithms that change the virtual point values for that data source will be run.
