Chapter 5 LabVIEW RT Programming© National Instruments Corporation 5-7 FP-2000/2010/2015 User ManualSelect Launch Application at Boot-up to launch the application specifiedin Application Path when you start up the FP-20xx. You must first createthe application using the Application Builder before you select this option.Refer to the LabVIEW Application Builder Release Notes and to theLabVIEW Help for more information about the Application Builder. Referto the Embedding Applications on the FP-20xx section for moreinformation about creating LabVIEW RT applications.By changing the Application Path, you can create multiple LabVIEW RTapplications on the FP-20xx. However, only the application you specifyin the Application Path launches at startup, if you select LaunchApplication at Boot-up.Use Downloaded VI Path to specify the default path for the RT Engine VIsdownloaded by the RT Development System. VIs are stored on the host PChard drive and are opened in the host RT Development System. Therefore,the RT Engine does not know the actual path of the downloaded VIs.The RT Engine uses the path specified in Downloaded VI Path foroperations that require the VI path. For example, the file constant CurrentVI’s Path normally returns the path of the VI in which the constant is used.This constant may be used in a VI that reads or writes data to a file on thedisk. When you run this VI in the LabVIEW RT Engine on the FP-20xx,Current VI’s Path returns the path specified in the Downloaded VI Pathoption, appended with the name of the VI.Embedding Applications on the FP-20xxLabVIEW RT applications built on the host PC with the ApplicationBuilder can be embedded on your FP-20xx. This section explains how toembed LabVIEW RT applications on your FP-20xx by using theApplication Builder while LabVIEW RT is targeted to the controller.Refer to Chapter 3, Software Overview, of the LabVIEW RT User Manualfor more information about building LabVIEW RT applications on the hostPC. Refer to the LabVIEW Application Builder Release Notes and to theLabVIEW Help for more information about using the Application Builderon the host PC.Command Line ArgumentsUse command line arguments for applications built on the host PC todisable the Select Target Platform dialog box and explicitly specify a targetfor the application. You can use these command line arguments ina shortcut from your Windows Startup folder to automatically launch
