Record by press of button

[John Rich]

Aquaphire,

The example that johnsold gave you appears to be the approach that you need with only one modification. The mechanical action of the write button needs to be changed to "latch when released" as suggested by altenbach. If you do this every time you press the write button it will execute the write routine one time. Since the button reverts back to false the next time through the loop it will just wait 200 ms and loop again. It will write again only when you press the write button. It will continue doing this until you press the stop button. You should always include a way to exit your program without using the Abort button (the Stop sign on the tool bar). The abort button is intended for use during development, not at runtime. This is why johnsold used two buttons.

I can't save to 6.1 but here is a picture of the diagram. the trick is to put your file open and close outside of the loop and now only when you click the timestamp button it will log. then it will give you time to stop the program whenever you want

the "magic" vi that i used was the " array to spreadsheet string" in the string menu.

let me know if this helps

Hi

I am facing one problem of similar kind. I want the button to come to default position after pressing. But i am using the refrence property of the button it does not allow to use Latch property. If i make it work with any of the switch property it sends more than one "true" value at the single time. What is the way to make the button work like Latch when released with refrence property too.

Thanks for your help.
