Create a command library subvi

[secr1973]

I am making a user interface that runs different tests that involve some motion commands.  The motion commands are simply sending a string command to a DLL file.  Is there a way that I can group all of my motion commands (like move up, move down, stop, pump on, etc...) into one subvi and then call whatever command I need in the main vi?  I hope that makes sense.  Thanks

Sure there is!  

Oh yeah - you probably want the details...

Well one thing you can do is start with the VI you have now for talking to the device and replace whatever is feeding string to the IO routines now with a case structure. Next, put all the various strings in the case structure (one string per frame, please) and then wire an enum control to the selector node on the case structure. Finally, create an enumeration for each operation (move up, move down, stop, pump on, etc...). Now which ever string you select will be sent to the IO routines.

And make the enum a type def, or you'll have to replace them all if you add
one item!
