elapsed time

[NathanL1989]

The attached is a picture of a timer program.

I need to run the big while loop for 3 times, each time for a 5s+5s time elapse.

The problem is that the program stuck at the second elapsed time in the first loop,

and remains there until all 3 big loops end. The first 2 films were not executed any more

and it never reaches the last film.

Without knowing how any of the express VIs are setup, I'm guessing you need to reset the Elapsed Time on the first iteration of its while loop.

I question whether this is necessary.  Why not use the Wait (ms) with a 5000 wired to it.  That would be a lot cleaner than an Elapsed Time inside of a while loop.

stay away from sequenced events, especially in your case where you want to run multiple times of the same event...change it over to a simple state machine with your timer and a shift reg. to keep track of your #cycles . case structure would be:

1. "initialize"
2. "state 1" timed event 1
3. "state 2" timed event 2, add +1 to #cycles shift reg., if #cycles not = 3...go back to "state 1"
4. if #cycles  = 3...then goto "exit" case.
