How do I carry an argument from one running vi to another with haveing them connected?

[Bobca]

I have one vi, monitoring vi, that aquires data and creates it into a file. It aquires this data at diferent time intervals. Then monitoring will exec another vi called BMO.vi. The BMO needs to take the file that monitoring has created and analyize it. Everything works except for the BMO recieving the new file. The monitoring vi has a file to execute parameter that executes the bmo.vi. I just need to be able to carry an argument from the monitoring.vi to the bmo.vi and the data would be diferent every time new data was aquired.

Forgive me if I've understood your question wrong. It seems to me that the best solution to this is to use the connector pane of a VI. You can wire controls and indicators of a VI to a front connector pane. Therefore, when this VI is "dropped" into the diagram of another VI, you can pass arguments into it (including a filename) and read outputs from it.

On your BMO VI, go to the front panel. On the upper right hand corner is an icon of the VI. Right click on it, and select "Show Connector". The connector pane of this VI is shown. Usually, it defaults to a connector pane which has a suitable number of input and output terminals for the number of controls and indicators on your front panel. As a rule of thumb, though, I select a connector pane which has 3 or 4
more terminals than what I need, so I can expand later if I need them.

Right click on the connector pane on the upper right hand corner again, and select "Patterns". This will allow you to select the connector pane you wish to use. Normally, inputs are wired to the left or top of the VI; outputs are to the right or bottom.

Now that you have your connector pane picked, wire your controls/indicators to the pane by using the wiring tool and clicking once on the control/indicator, and then once on the terminal you wish to use. (Controls are inputs, indicators are outputs)

Save the VI. Now, when you put that VI on the diagram of another VI, you can wire arguments to it to get the correct file, etc.
