When looking for a problem in your code, you may have an idea of the general area where the problem exists. To help focus on this area, you can use a breakpoint to pause the VI at a specified point in the program. When the VI reaches a breakpoint during execution, you can take the following actions:
  • Single-step through execution using the single-stepping buttons.
  • Check intermediate values on probes that you placed on wires prior to running the VI.
  • Change values of panel controls.
  • Click the Resume button to continue running to the next breakpoint or until the VI finishes running.

You can add a breakpoint on any wire or node in the code by clicking the wire or node and selecting Breakpoint»Set Breakpoint on the Debug tab.
