trigger led when value exceeds

[zanki29]

Hey everyone! I have to do a project and im stuck becouse i'm a noobler in regards to labview. I'm using labview 6 and i have to monitor the pressure and temperature of a reactor in time. I have to create a system in wich if a value exceeds it triggers an alarm(maybe led can show it) or is below a certain limit. I mean it must trigger an alarm when temperature or presure is beyond 100 and below 10. And after that to generate a text document in which it is specified the hour and date at which those values have exceeded. I also have to use random generated values. Can i get some help please? I am not managing this by myself:))

You are looking for a shift register to hold the value and the In Range and Coerce function for checking the limits.

Hi zanki,

apart from using ancient LabVIEW6 this all sounds like a regular homework. Is it so?

Well, when starting to work with LabVIEW you should take all those FREE online courses offered by NI on their website. After going through them you can study all thos eexample VIs coming with LabVIEW. Then you should be able to create that small program according to your description!

Yes it's a homework and i would do all these courses if i wasn't time pressured by a thousand exams:)) could anyone make my project with just the temperature so i can get the jest of it and apply it to the rest of the project? I would be forever grateful to any who gets me unstuck from this:)

Hi zanki,

why should we do so?

You want to earn some points on your way to a university degree - so you you need to do the work!

Usually this forum works the other way around: you post your work and ask specific questions and we provide (possible) solutions to your current problems.

When you want someone to write your program you will find a special "Job offer" thread in the NI forums!

In Range and Coerce. as Norbert said.

You won't get much sympathy about being overloaded around here.  Three things occurred to me as I read your posts:

1. You'll be in trouble when you get an engineering position if you think you won't always be loaded.
2. If I help you, you'll probably end up working for me and I'll always have to do your homework.
3. You'll be fine.  Engineers outsource their work all the time. 😄

I just asked for a bit of guidance on a forum where many labview enthusiasts have gathered... I did not ask for much and to be honest i just layed the problem here in hopes someone could help a fellow human, not to get lectures. But this is a prime example of how we act when someone asks for a little help...Thank you kind sir.

Thanks Jim:) got buck-load of stuff to recuperate since i've been in hospital after a car accident and my laptop in that place would have been a liability:) I won't work with this program after this semester and i'm hoping to work on Solidedge and CAD after this:)

Hi zanki,

yes, you asked for guidance. And you got guidance with mentioning all the free courses available online!

It's your fault you asked too late, shortly before due time… (To add to other comments: As an engineer you also should have learned to manage your time.)

zanki29,

that remark regarding homework stuff is nothing agains YOU specifically. In fact, you asked in a rather nice manner.

But it is the question itself, which implies:

"Please, provide me a fully functional application for free as i am not able (unskilled) or unwilling (lazy) to implement it on my own."

Honestly, the reaction came up as you seemed to ignore my recommendation and asked for a ready-to-go example instead.

So next time, instead of asking for a finished example, take your time to read all answers, try some things out and then POST what you tried.

That makes people around here much more commiting in helping you!
