store values from waveform and go back to them

[Justus Jonas]

Hi everybody,

I have a problem with my waveform. With this VI I want to protocol the incoming values over the current time so that I can scroll back the time and see, for example, when a peak happened. What I have is a waveform that has the current time in the x-Axis, but I can’t scroll back.

What I want to know is:

·        How can I store the values for maybe the last 12 hours so that I can scroll back the waveform?

·        If that is possible, can I fill a various beginning time and an end time in a part of the VI (maybe a time stamp control) and the values of this period are shown? (Like scrolling back but just flipping by time entry)

I have a VI that shows it. (The two time stamp controls are blind. (Just to illustrate!))

Thanks for the help

NI provides a tool for this type of application called "VI Logger". For more sophisticated solutions please visit this link.

I hope that helps,
