Getting Started with Trend Recording

To execute trend recording on a runtime system, you need an application with a TrendRecordingManager object that contains at least one TrendRecording object. Then you can configure a database on the runtime system and the data buffering.

  1. Add a TrendRecordingManager object below your application.

  2. Select the TrendRecordingManager object and click Add Object ‣ Trend recording. Type a name in the Add Trend recording dialog box.

    ⇒

    CODESYS creates the object. The editor opens.

  3. Type a task in Record Settings.

  4. Click Add variable.

    ⇒

    CODESYS adds another variables. The blank settings open in the Variable Settings to the right of the tree view.

  5. Select a valid IEC variable from the Variable field.

    ⇒

    The IEC variable is configured for trend recording.

  6. Build the application.

  7. Download the application to the controller and click Start.

    ⇒

    The application records data in runtime mode and saves it to a database.
