LabvIEW Error 7 When Using Command Line Interface RunVI Command

Issue Details

• I am trying to use the LabVIEW Command Line Interface (CLI) to execute the RunVI command. When I do that, the output returns error 7. What do I do?
• When I use the RunVI operation with LabVIEW CLI, I receive the below error. What causes this?

Error Code : 7 
Error Message : Open VI Reference in RunVI.lvclass:RunOperation.vi:5910001->CoreOperation.lvclass:CallRunOperation.vi:4230002->ExecuteRunOperation.vi:5250001->ExecuteOperation.vi:6900002->ExecuteOperation.vi.ProxyCaller<APPEND> 
VI Path: <b>C:\test.vi</b> 
An error occurred while running the RunVI operation. 

RunVI operation failed. 

 

Solution

This error can occur when the path to the VI is incorrect, or the configuration of the VI's arguments and inputs are incorrect.

Follow the steps below to resolve this error:

• Double-check that the VI's path is entered correctly. The full command should take the form LabVIEWCLI -OperationName RunVI -VIPath "<Path>" <Arguments>.
• The VI's Connector Pane is required to take the form of the below image, where:
  • 1 is an array of Strings as a Control.
  • 2 is an I32 Numeric Indicator.
  • 3 is a String Indicator.

• When passing arguments into the VI, ensure that they are separated with spaces. For example, passing arguments one and two will take the form LabVIEWCLI -OperationName RunVI -VIPath "<Path>" one two.
