using formula in Labview to calculate with variables and functions

[Anh To]

Hi,

i am using labview to acquire data from DAQ device, and process these data. I am using Fomula Express VI to convert the voltage signals to desired values. But i don't know how to add different variables and functions as well as get different results in one Formula Express VI. Please show me how to do this

Thanks

Anh

Hi Anh,

       Can you please expand on what you mean by adding different variables and functions?  Would you mind posting the equations you are trying to complete?  I would recommend first starting at the  LabVIEW Help Page on this topic.  Thanks!

we can input 8 variables in the Formula (from X1-X8), but when i open the Formula VI, it's only have one input (X1). So how can i add more inputs for this.

Besides, i also want to make 4 functions in the Configure formula area. How can i enter the functions?

You get another input as soon as you click on one.

You can only have a single formula.  There are the different text based functions such as the formula node, mathscript node, etc where you can have multiple formulas and outputs or just use the basic math functions.
