Saves the deployed configuration of processes or shared variables to a library. Details
Use the pull-down menu to select an instance of this VI.
Save to Library (Process)
 |
process specifies the process whose configuration you want to save to a library. | ||||||
 |
library path specifies the name of the library in which you want to save the configuration.
When you use the Process instance of the Save to Library VI, you can specify a library name with or without an .lvlib extension. If you use an .lvlib extension, LabVIEW saves the configuration to a library with the name you specify. If you do not use an .lvlib extension, LabVIEW creates a subdirectory with the name you specify. LabVIEW then saves the configuration to a library within that subdirectory with the same name as the original process. When you use the Shared Variables instance of the Save to Library VI, you must specify a library name with an .lvlib extension. |
||||||
 |
error in describes error conditions that occur before this VI or function runs.
The default is no error. If an error occurred before this VI or function runs, the VI or function passes the error in value to error out. This VI or function runs normally only if no error occurred before this VI or function runs. If an error occurs while this VI or function runs, it runs normally and sets its own error status in error out. Use the Simple Error Handler or General Error Handler VIs to display the description of the error code. Use error in and error out to check errors and to specify execution order by wiring error out from one node to error in of the next node.
| ||||||
 |
complete path returns the complete path to the library in which LabVIEW saved the configuration. | ||||||
 |
error out contains error information. If error in indicates that an error occurred before this VI or function ran, error out contains the same error information. Otherwise, it describes the error status that this VI or function produces.
Right-click the error out front panel indicator and select Explain Error from the shortcut menu for more information about the error.

Save to Library (Shared Variables)
 |
shared variables specifies the shared variables whose configuration you want to save to a library. | ||||||
|
library path specifies the name of the library in which you want to save the configuration.
When you use the Process instance of the Save to Library VI, you can specify a library name with or without an .lvlib extension. If you use an .lvlib extension, LabVIEW saves the configuration to a library with the name you specify. If you do not use an .lvlib extension, LabVIEW creates a subdirectory with the name you specify. LabVIEW then saves the configuration to a library within that subdirectory with the same name as the original process. When you use the Shared Variables instance of the Save to Library VI, you must specify a library name with an .lvlib extension. |

Save to Library Details
If the original process or shared variables array contains items that do not exist in the library you specify in library path, this VI does not delete those items. This VI only overwrites existing configurations and adds new items. For example, suppose the original process contains two shared variables: var1 and var2. You want to save this process to an existing library, MyLib, which already has two shared variables: var1 and var3. When you execute the Save to Library VI, the resulting MyLib library contains three variables: var1, var2, and var3. LabVIEW overwrites the configuration of the var1 shared variable from the original process with that of the var1 shared variable in MyLib.
