instances

[Ranjeet_Singh]

Hello all,

                               Can you please tell me how to open multiple instances of same SubVI. One standard method which i know is to convert the vi into vit, use open reference,  for loop & convert the subvi exection to reentrant. which is described here. 

                                But i cant use this because i need to pass data to subVI & based on this input only subVI will process the data. If using this method i can pass the data than its great 

Problem ?

A subVI which i want in multiple instances will execute different task based on the passed value from the called VI but front panel will same.

Hi Ranjeet,

set that subVI to reentrant, so each instance in the code will run in parallel with all other...

I tried this also than also its not working.

I am sending you my code.

Please let me know. 

Each time you press add button from the master.vi by entering the different value. Its creating only value

I'm not seeing what your problem is.  With the VI set to reentrant, you can just call the VI directly in parallel.  With the example you gave, you can only run 1 task at a time.  Are you trying to get them to run in parallel?

Hi Ranjeet,

your subVI can only produce one result from it's inputs as it is working with scalar in-/outputs. What else do you expect?

Right now your subVI will block the mainVI from execution as the mainVI has to wait for the subVI to finish...

Hey,

                Thanks for your time, I just want to call slave.vi from master.vi as soon as i press add from master.vi.

My slave.vi is reentrant. This is what multiple instances means.. am i right ?

i just want to acheive that as soon as user presses add from master.vi by entering different value from master front panel. The slave should add the value & present to output.

Just want multiple run slave.vi parallely.

Hi Ranjeet,

your slave already does what you want it to do: as soon as you press the ADD button the slave is called and presents the result of the addition...

Oh, you edited your message:

To call the slave in parallel you have to program it in a parallel fashion. Right now there is only one instance...

Maybe you need the Asynchronous Call By Reference:

Start Asynchronous Call Node

Wait On Asynchronous Call Node

Hi GerdW,

                                I want to run each slave.vi parallely.....tell me how can i program it

[Ranjeet_Singh]

hi crossrulz,

                                 Can u elobate how can i acheive this. How can i acheive the parallel using the solution
