Software

  • LabVIEW

Issue Details

  • I have a clone subVI and I want to know its properties, but VI Properties are greyed out and cannot be clicked.

  • I have changed DAQmx Read subVI in my main VI before I run my main VI, but after that I checked the DAQmx Read subVI, it became clone, and I cannot open its VI Properties. 

Solution

You cannot click VI Properties of a clone subVI, and its properties cannot be edited.
One of the reasons it becomes a clone subVI is, its VI Properties > Execution > Preallocated clone reentrant execution box is tick.


DAQmx Read vi VI Properties

Regarding the VI properties of the clone subVI, it has the latest VI properties as you set before it become clone VI. 

To check or to confirm its VI Properties:

  1. Double-click the clone subVI to open the subVI

  2. Press CTRL + M

  3. Go to File > VI Properties
