In Darren's Occasional Nugget 02/23/2018, Darren Nattinger talks about "probes you can place on wires in LabVIEW that don't actually care about the value being passed through the wire, so much as they care that data has passed through the wire."
These probes open up all sorts of possibilities. You can place the probe on any wire, regardless of the data type of the wire. One way of applying this is to measure the time that passes in between data flowing through the wires the probe was put on.
This may sound a little abstract here, but read his blog post and take a look at the 'Timing Probe' example at https://forums.ni.com/t5/LabVIEW/Darren-s-Occasional-Nugget-02-23-2018/m-p/3759109?lang=en to learn more about this very handy feature.
