How LabVIEW Highlights Breakpoints

The following table indicates how LabVIEW highlights a breakpoint and when execution pauses.

Location of Breakpoint How Breakpoint is Highlighted When Pause Occurs
Block diagram/structure example Red border around block diagram. If the block diagram is inside a structure, the structure includes the red border. When all nodes on the block diagram finish running. If a breakpoint is in a loop structure, the pause occurs after each loop iteration.
Node example Red border around the node. Just before the node executes. You can probe all the input signals into the node with the Probe tool.
Wire example Red bullet in the middle of wire. If you attach a probe to the wire, the probe also has a red border. After data pass through the wire and the probe displays the data.
