Select Launch Application at Boot-up to launch the application specified
in Application Path when you start up the FP-20xx. You must first create
the application using the Application Builder before you select this option.
Refer to the LabVIEW Application Builder Release Notes andtothe
LabVIEW Help for more information about the Application Builder. Refer
to the Embedding Applications on the FP-20xx section for more
information about creating LabVIEW RT applications.
By changing the Application Path, you can create multiple LabVIEW RT
applications on the FP-20xx. However, only the application you specify
in the Application Path launches at startup, if you select Launch
Application at Boot-up.
Use Downloaded VI Path to specify the default path for the RT Engine VIs
downloaded by the RT Development System. VIs are stored on the host PC
hard 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 for
operations that require the VI path. For example, the file constant Current
VI’sPathnormally 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 the
disk. 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 Path
option, appended with the name of the VI.
Embedding Applications on the FP-20xx
LabVIEW RT applications built on the host PC with the Application
Builder can be embedded on your FP-20xx. This section explains how to
embed LabVIEW RT applications on your FP-20xx by using the
Application Builder while LabVIEW RT is targeted to the controller.
Refer to Chapter 3, Software Overview,oftheLabVIEW RT User Manual
for more information about building LabVIEW RT applications on the host
PC. Refer to the LabVIEW Application Builder Release Notes andtothe
LabVIEW Help for more information about using the Application Builder
on the host PC.
Command Line Arguments
Use command line arguments for applications built on the host PC to
disable the Select Target Platform dialog box and explicitly specify a target
for the application. You can use these command line arguments in
a shortcut from your Windows Startup folder to automatically launch
