Thank you very much. This is something i wanted.

 

 

Secondly, i want to ask you a question regarding the same VI

 

I hope you have the PID toolkit and you are able to run the VI.

 

In simple words, if you change the value of 0 to 1 for lower limit in "In range and coerce VI", you will observe a different green waveform.

 
What i want is that i should be able to get both functions without changing the numbers for 0 to 1.

 

This is certainly the best way i can explain my situation

 

Thanks

Do you mean that you want the same answer no matter if the value is 1 or zero? I am not sure exactly what you are asking for.

If you run the VI with '0' value, the green will jump only if white > red and stays with white line until green has reached maximum value 1 .

 

IF the vi continues, the green shoud not stay with white until white < red.

 

 

Please dont bother changing the value to 1 if you can figure out the above statement.

Well what I would assume is the problem is the in range function you are not including 1 in the upper limit. See if you right click on the in range function and include the upper limit of 1 if that helps.

I do not have the PID tool kit so I can not run your vi. I had to make my own. I work in the automotive industry and we do not get all the bells and whistles. I have had to generate my own code for a lot of things there are tool kits for.

 

I am sorry that I can not help much more since I do not have the PID toolkit and I do not understand what you are looking for without it.

Is there any way i could know the intercept values for my plots, for example, when my White plot intersects the Red plot, it should read both values, store only those 2 values and measure the time between them

 

By the way i am also from the automotive company.

I usually download the evaluation version of the toolkit i need and if i need it further i just reinstall it

Do you have data that I could look at? I would be happy to help with the data and analysis. Just save what you have in a graph and make it the default data and I will see what I can do for you.

 

What company do you work for?
