Getting Started with Trend Recording
To execute trend recording on a runtime system, you need an application with a Trend Recording Manager object that contains at least one Trend Recording object. Then you can configure a database on the runtime system and the data buffering.
Add a Trend Recording Manager object below your application.
Select the Trend Recording Manager object and click . Type a name in the Add Trend Recording dialog.
The object is created and the editor opens.
Type a time interval in Record Settings.
Click Add Variable.
An additional variable has been added. The blank settings open in the Variable Settings to the right of the tree view.
Select a valid IEC variable from the Variable field.
The IEC variable is configured for trend recording.
Build the application.
Download the application to the controller and click Start.
The application records data at runtime and saves it to a database.
