Using Probes to Check Values on a Wire
When your WebVI is running in the editor environment, you may want to check the values on the wires to determine if and where any unexpected data occurs.
To place a probe on a wire, right-click on the wire and select Add Probe. A probe displays the data from the wire it is on. To view a probe in a temporary overlay on the diagram, hover over the probe marker on a wire. If desired, you can then click the Pin button to keep this probe visible. From the Options drop-down you can choose the different display styles and also remove the probe, as required.
You can also find probes in the Debugging tab on the left side of the editor environment. The order in the list correlates with the numbers in the probe markers on the wires.
Probes display the most recent value carried by a wire. You can hover over the probes in the list and observe the tip strip that specifies when the value was last updated.
The values displayed in the probe list are limited to a line of text. However, you can hover over a probe and click the > button to display an expanded view of the probe and the Options drop-down.
