Dependent Sub-VIs

[Vicen]

Hello,

I have downloaded a program, the ‘USB-6501 Interactive Control’ and I’m surprised because there is only one Sub-Vi, but it appears four times. If I change something in one Sub-VI, the rest of Sub-Vis will automatically be changed and that’s not what I need to do. In fact, I would like to use every Sub-VI independently and do different modifications. Does anybody know what I need to change to have four independent Sub-Vis? I guess it will be an option somewhere.

Thanks in advance.

Go to explorer and make 4 copies of the VI, then open the main VI and replace each instance with a different copy.

Since you only have 4 this should suffice.

Hi,

What André said is correct. When you call a sub VI, you refer to that sub VI like a function call. If you change the sub VI, the function you are calling (all four instances of it) is altered. Therefore by making 4 copies of the file on your hard drive, you are effectively calling 4 separate functions. You can then alter each function individually for use in your VI.
