Meta Data Points are Data Points like any other except they get their value from other Data Points in the system using a script. The result of the script is returned as the Meta Data Point's value.

Meta Data Points are extremely powerful and the capabilities of the scripts are far reaching. See: Meta Data Point Scripts for more information.

Creating Meta Data Points
Meta Data Points are created by first creating a Meta Data Source and then adding points.

The Scripting Data Source uses scripts very similar to the Meta Data Points but the scripts are used to set the value of other Data Points in the system. Scripts can be used to perform controls and actions within the system. See Scripting Data Source for more information.
