Hello! pls, can anyone help. I am new to Labview, having three input variables x,y,z entering a tank(indicator) at the same time,but not mixed?

pls, you wish to look at the attachment, where x,y,z are the inputs, i tried but have difficulty, i assigned three control to represent x,y,z, because thier values varies and the tank be represented by an indicator, but cannot be connected together. I tried bundle/unbundle, build array but doesnot work.Thanks

That figure is meaningless. What is "u"? What is "y"? What is "s"? What is "G"? Is G a transfer function? What is the tank supposed to do? You said it's supposed to "mix" the "variables". What does that mean? A tank is just a numeric control/indicator. It's not an object. It cannot perform magic on your numbers. You have to put the smarts into your code to perform the operations required. Perhaps what you're really looking for is the Simulation Toolkit for LabVIEW.

Unless you provide more information as to what the process is, this guessing game is just going to go on forever.

Is THIS your card???...  (You need to show us your coding attempts or try to be more clear in your questions)

This sounds like homework and though we're willing to get you started and advise, you should not expect us to do all the work.

Are you trying to simulate the tank? Do you have the model (First order differential equations) ? 

You can use CD&Sim which is our control design and simulation module, if this what you are trying to do.

Your posting is a bit confusing, please elaborate on what you are trying to do...

The guessing game continues

Just going on this statement the OP stated

So is't possible to assign 3 numeric control to represent the variable and one indicator to represent tank?

---

Does the OP mean to display the 3 numeric inputs on a single tank?

Thank you all, i am simualting a system, on the simulation loop equations are well presented using formula node, my problem is on the front panel, the input variables goes to a 1st tank, where inside they are mixed, the mixture now goes to a second tank, how do i represent this on the front panel. Thanks

Hi DALIB,

If you think really you need the answers. you have to post your code. otherwise No one can understand your question. I think you are playing with the forum.

Now leave all the other things. First post your vi. Then continue your questions...

This simulation concept is like a school project.

Show your effort first.

I think others in the forum doing your home work.

<<Kudos are welcome>>

Yes, but when i bundled them using bundle, the output of the bundle cannot be connected directly to the tank. how do i pass the cluster to the tank? Thanks so much for ur concern

[Abul]

Yes, i wanted to see x,y,z in the tank, i bundled them using bundle, i tried to connect to the tank but shows error. how do i pass them to the tank?

Thanks so much for ur concern

[NIquist]

Bundle has nothing to do with mixing variables.  It is just used to combine similar controls/indicators so there are not so many wires on your block diagram and to make code easier to understand. 

You need to go back to the LabVIEW tutorials and learn the basics before you attempt your project.

To wire a cluster to a tank indicator you need to add sliders to the tank so that the number of sliders is one less than the number of elements in the cluster. If you have a cluster of 3 numbers then you need to add 2 sliders to the tank. You willl need to change the colors of the sliders (which you can do on the Properties page for the tank indicator). You may also need to change the fill options to make the individual parts visible. Please review the documentation on tanks and how to customize sliders.
