Running multiple copies of Sub VI in parallel

[Arkady_V]

I'm developing the life test of 2-way switches, my test setup consists of NI PXI system with up to 6 DMM's and up to six USB 4-way switches to control the devices under test. I have a Sub VI that sends the path word to the 4-way switch and takes a measurement with PXI. I can now run number of copies of this Sub VI in parallel and fetch the measurement from up to 24 DUT's. It's working good.

But I have now up to 6 separate While loops, each of them is running one statically created copy of my Switch&Measurement Sub VI. What if I want to use only 2 or 3 4-way switches? My question is, how to call my Sub VI dynamically, so it still be running in parallel with itself?

This snip shows one method of launching a dynamic number of clones of a vi.  Save the attached vi where you can find it.  Drop this snip on a blank BD.  Edit the path to point to your path to the attached vi and change Numeric control to play with it youself.

Jeff,

Thank you, I've got the idea. Is it possible to modify your example slightly to make the clones run in subpanels of the Main VI? Say I have 6 subpanels and I want first n (n<6) of them to display the clones of the Reenterant.vi.

UPD. I accidentally figured out myself how to do it. Required me to change options from 0xC0 to 0x80. Thank you again.

yes, you can't fire and forget a vi in a subpanel.  you need to fire and remember.
