Problem with time

[microes]

Hi everyone,

i'm new at labview so hopefully there's someone out there to show me some solutions to my problem.

Attached is a problem which i just started. The purpose of the program is to enable the user to input the testing time *seconds* and the block diagram is suppose to increase the starting time from zero seconds onwards until it reaches more than the input value. I included a Get time/date in seconds in order to get the precise value for the counting but somehow it prompts me to indicate where i should save my data at instead of continuously running in the while loop.

Elapse time should show me how the time is being run *in action* when the vi is being executed but it doesn't work either.

What's wrong with my code and what can i do to resolve this?

Many thanks!

Please post your code or at least a screenshot. This will save our precious time and is the best guarantee to receive a useful answer...

Sorry for my previous posting. Your code arrived will I was typing my answer.

The loop executes only once because you have wired a TRUE constant to its conditional terminal set to Stop if True ! Set the constant to FALSE or change the behavior of the conditional terminal. Please read the context help of the loop.

I also strongly suggest to replace the constant by a boolean button. This will allow you to stop the loop.

An example is better than 1000 words...

Don't forget to set the Testing Time to a value different to 0.

Hi JB,

thanks for your revised vi. I was wondering if is critical to install a Wait(ms) inside the loop?

Thank you once again!

Not critical (unless your development computer runs a nucelar power plant)
But not including any wait inside a while loop (even 0 ms) will call all the computation power of the CPU.

Hi there,

now i would like to display the elapse time in terms of date and time in a text format. I experimented with Format Date/TIme String but in vain.

is it possible to do that since the diagram is running based on taking account of the real time offset with the user's input?

Thank you!
