As requested, you need to post a better description of the problem you are having. What things have you tried already and what is the exact nature of your project. In addition, if this is a homework assignment please state that. Folks here are more than willing to help but we won't do your homework for you.

this is not my home work but my university project..

The main objective of this project is to discuss the automation of a greenhouse using

Supervisory Control and Data Acquisition (SCADA) systems and LabVIEW program.

The automation includes temperature and humidity so the

client can monitor and make the suitable control for the greenhouse from his office.

thank you for all..

A good starting point might be the temperature system demo in the examples directory. It demonstrates alarm (over temp, under temp) detection and would at least provide a frame of reference for you to ask specific questions.

Its better to post in this forum. Then others may learn from the questions and answers.

Well it looks correct to me, but it's just kind of unfinished. Though maybe you want the dehumidifier ON when humidity is high.

So isn't there anyone at the university who is paid to help you figure out your homework project, like a Teaching Assistant? I'm not sure this board is the right place to get all the support you need.

there is some wrongs.

The first thing I noticed was that the control you're using to stop the while loops is located OUTSIDE of them. That control will be read once before the loops start and the loops will never stop (without aborting execution). It doesn't look like you're very close to being done.

Here's an example that demonstrates using a Notifier to stop parallel loops. You can put your code in these and your VI will stop cleanly.

[ShaunR]

Well.

You don't have much for us to go on.

In your temp vi, you don't really need 2 loops but it a long, long way from being able to manage a greenhouse. Did you take a look at the example in the examples directory. I think your lecturer might be looking for something like that for a remote monitoring system.

In your other VI its not really defined what you want to do?

Is there a temperature and humidity control for each crop? Or will it tell the greengrocer how much the seeds are.

[angel_22]

yes there is a temperature and humidity control for each crop but i choose tomato

this is last work ,,these are true?? i want to begun the system with username and bassowrd befoer entering the system, how??

where are you???

i want the method to bigun the system with logon widow

please reply

thanks

[asbo]

Two people before me have told you to look at the examples - you really need to start taking their advice. There's an example of how to do a login dialog and already includes outputs indicating the result of the login attempt.

lol.Some of us have to work for a living!

As Asbo said. there's an example.

Your UI is comming along nicely. You obviously have an artistic flair which I severely lack.

Is this software actually going to control anything? Or is it a proof of concept?

[angel_22]

thank you very much..

this apploied in urop..

are you know how i can do with logon or not??

i am implement this example but the window not closed when another widow opened..no problem i am canceled that,,

i am going with DSC , i create library and periodic I/O server ,,while i deploying the periodic I/O for choose and temp,humidity windows.. there i didn't find the monitoring variables in tool menue..

what can i do??

this will be necessary step???

i am take these steps from Download File:post-15384-1242855670.pdf

This reminds me of my Senior year in High School when my Electronics lab partner told me to "hurry up and fix it, I want to get this done."
