Setting up the VI Revision History

Use the History window in each VI to display the development history of the VI, including revision numbers. Record and track the changes you make to the VI in the History window as you make them. Select Tools»VI Revision History to display the History window.

You can set options for, add comments to, view, reset, and print the revision history.

The revision number is an easy way to track changes to a VI. The revision number starts at zero and increases incrementally every time you save the VI. The current revision number stored on disk appears in the History window. To display the current revision number in the titlebar of the VI, select Tools»Options to display the Options dialog box, select Revision History from the Category pull-down menu, and place a checkmark in the Show revision number in titlebar checkbox. The header of the comment includes the next revision number. The revision number does not increase when you save a VI if you change only the History window.
