You can request repair, schedule calibration, or get technical support. A valid service agreement may be required.
Provides support for NI data acquisition and signal conditioning devices.
Provides support for Ethernet, GPIB, serial, USB, and other types of instruments.
Provides support for NI GPIB controllers and NI embedded controllers with GPIB ports.
Obtains a reference to a file so that you can use the file in a program.
Custom message that appears in the title bar of the file dialog box that appears when you do not wire a value to file path.
Absolute path to the file you want to open.
If you do not wire a value to file path, this node displays a file browser from which you can select a file. If you specify an empty or relative path, this function returns an error.
Action that this node is allowed to perform on the specified file.
Opens an existing file.
Replaces an existing file by opening the file and setting its end of file to 0.
Creates a new file.
Opens an existing file or creates a new file if one does not exist.
Creates a new file or replaces a file if it exists. This node replaces a file by opening the file and setting its end of file to 0.
Creates a new file or replaces a file if it exists and you give permission. This VI replaces a file by opening the file and setting its end of file to 0.
Allowable ways to access the returned file.
Allows you to read or write to the returned file.
Allows you to read from the returned file.
Allows you to write to the returned file.
Error conditions that occur before this node runs.
The node responds to this input according to standard error behavior.
Default: no error
A Boolean that specifies whether LabVIEW opens the file without buffering, which, for large amounts of data, may increase the rate of data transfer to the file.
Reference to the open file.
If the file cannot be opened, the value of this output is Not A Refnum.
A Boolean that specifies whether the user cancelled the file browser or did not select a replacement in an advisory dialog box.
The node produces this output according to standard error behavior.
This node can return the following error codes.
This is not a comprehensive list of errors this node can return.
Installed By: LabVIEW Communications System Design Suite (introduced in 1.0)
