I/O direction of LabView shared variable?

[JAF]

Can I programmatically change the I/O direction of a LabView shared variable?  I'm using LV 2010 and I'm trying to change the I/O direction of a NI 9403 module programmatically.  Is this possible?

Hi JAF,

I'm assuming your intended purpose is to input and output data through the same DIO line.  

In that case, I would recommend using a case structure. You would need to create a case for input data and another case for the output.

Below is a link describing the characteristics of a case structure.

I hope this helps. BTW, are you using a cRIO? I'm just curious.
