Get Date/Time in Seconds Tunnel Structure

[pj1390]

Hi all,

Quick question regarding passing inputs into a while loop. Maybe I am missing something but after reading this tutorial it seems as though you can only pass an input into the loop during the first iteration. I am confused because if you wire a Get Date/Time in Seconds timestamp block from outside the loop, it passes in the timestamp every iteration.

Wondering if I am missing something here?

Thank you.

The value at a tunnel entering a loop stays the same for every iteration of the loop. The value is valid for every iteration but constant. If you wire in get date/time from outside the loop, the timestamp will be the same on every loop iteration.

Hi pj,

maybe you are missing the DATAFLOW as is explained tín the first chapter of the LabVIEW help?

Yep, I didn't realize the value was staying the same. That makes a lot of sense now.

Thank you both!
