File à Open / Open Button

  The Open menu option will allow the user to choose an existing Trend for the selected Digital Recorder Screen.  The Digital Screen that is highlighted will be one of the previously created profiles for a device.  The Trends that are available here have to be Synchronized with the Digital Screen in order to be up to date with the data logger and screen.  This is performed using the Synchronize option under the Tools ® Communications ® Advanced Download & Maintenance selection, or by clicking on the Download Data button on the top right of the screen.  See the section Tools ® Communications ® Advanced Download & Maintenance on page 59 for more information on the Download Data button and its features.

The Open button will look at the Trends that have been downloaded and allow the operator to select one of the previously setup trends.  This will display all the data associated to the Digital Recorder for the Trends selected. 

Trends consist of inputs for the specified device, alarms, function based timers, totalizers, and averagers.  Trends can be modified in the VR Manager, but the changes cannot be saved back to the data logger.
