Execute VI in certain hours

[Peter Saraiva]

Hi,

I want my VI to start (for example) at 9:00AM to 5:00PM (This hours should be customizable), when we are into this time slot I want to set a boolean at the value true. 

Any example please ?

Thanks;

Peter

In labview examples at the website:

Run a task that starts at a start time and stops at a stop time.

Why don't you just use the OS scheduling capabilities? Seems to me to be far easier.

Hi EmcV,

the solution that you gave to me is not exactly what I want, in fact my VI should be executed between 9:00 AM and 5:00 PM "every day" and your in your example it isn't that. How can I modify it to do what I want ?

So what is your problem with the windows scheduler solution that was given? Unless your VI is always running, you'll need another program to start it.

[Peter Saraiva]

Yes my VI is always running ...

[smercurio_fc]

Well, if your VI is always running, then what is the issue with the simple approach shown in the linked article? All you need to do is look at the current time and compare it to the set time, or a pair of set times if it has to run only between certain hours.

So then, I don't understand what your problem is. Doing a time comparison is pretty simple as the example shows. Attach your code with details on what does not work.

[EmcV]

For example:

To remove date just convert to number which just contains time string.

Probably there are more beautiful ways

[Peter Saraiva]

the problem with your example is that my program is always running and must do task in a  time slot every day.

EmcV you probably have the right solution : remove the date. Can you resend your VI example for the labview 9.0 version please.
