Probes
Use probes to see the data a step returns without having to place the data in a graph or table in the Data View. To use probes, right-click an input or output signal in the Project View and select Probe from the shortcut menu to display the Data Probe window. The Data Probe window displays information about the signal. The contents of the Data Probe window depend on the type of signal you probe, and you can probe multiple signals at once. Each probe you set displays data in a separate Data Probe window.
