How do you open a specified Labview Vi from a different Labview Vi?

[Wes Galliver]

I need to open a different Labview Vi when a certain function is performed from within my current Labview Vi.

You can do this using vi server. These functions are located under the "application control" palette. The first thing that you will need to do is open a vi reference. You can use the path of the vi you want to open to obtain this reference. Then you can use a combination or just one property node and invoke node from the same palette. There are also examples of this located in LV find examples. Type in server and you will find example vi's using vi server architechtures. Hope this helps.

Or just call a subVI statically. This is the simplest and most common method. Just exactly what are you trying to do?

[Wes Galliver]

When an Emergency Stop 'button' is pressed I wish to jump into a different Vi which will allow me to restart a sequence of events. When this Vi is complete, i want to return to the original Vi, containing the emergency stop function. I will try the SubVI method (I'm not a very experienced user though...).

It sounds like you can do this like Dennis said. Maybe try using a state machine architecture. hope this helps.

1) Use a "Open VI Reference"

(All Functions -> Application Control -> Open VI Refrence)

2) Connect a string (or path) with your VI's name into "VI Path" on
the "Open VI Reference"

3) Connect the "VI Reference" output to a "Property Node" reference
input.

(All Functions -> Application Control -> Property Node)

4) Right click on the "Property Node" and select:

Properties -> Front Panel Window -> Open

Wes,

The best way to achieve this will be to use a SubVI. As you are not too familiar with labview I suggest that you read over chapter 7 of the labview pdf manual (which is available from the help>search the labview bookshelf menu).

I hope that this helps you to resolve your problem.
