I am developing a test using TestStand, and I am using LabVIEW VI's as steps for it. However, when I point the Step Settings to my VI, I get the following error:
The parameters specified by the step do not match the controls and indicators of the VI, or the VI may be broken.
Click this icon to reload the prototype, which maps the current arguments to the controls and indicators wired to the VI connector pane.
If the error persists, open the VI in the LabVIEW development System and ensure it is not broken.
This error can happen for multiple reasons. We recommend trying the following:
LabVIEW VIs are saved with both their compiled code and block diagram. When TestStand makes calls to them using the Run-Time Engine, it uses the VI's compiled code to execute them. However, if this code is not available, or does not match the prototype that TestStand is expecting, it will throw this error.
Thank you for your feedback.
