Cross Platform VI Communication

[xkenneth]

Is it possible to easily communicate data between a VI running on different operating systems? OS X and Windows XP?

Regards,
Ken

Hi Ken,
you can use TCP/IP to send data. Or if you have LabView 8.x shared variables are also possible, but i prefer to build my own communication with TCP/IP.

Hope it helps.

I'd generally prefer not to write my own TCP/IP code, but I'll take a look at shared variables.

You can also use VI server to implement data communications by creating a functional global to hold the data you wish to transfer. Write data to the FG from the source system and then use VI Server to read the FG remotely.

Hello Ken,

Thank you for contacting National Instruments.  As some users have already stated, you can achieve this by using a TCP/IP connection or using shared variables.  Both implementations have their difficulties and I can understand that you would prefer to avoid using the TCP/IP connection. 

Here is some more information regarding the use of Shared Variables.  I would recommend utilizing the DataSocket API aspect of the shared variables.  This will allow you to dynamically change the shared variable that a VI reads and writes. You can change a shared variable dynamically by building the URL of the DataSocket connection programmatically.  Keep in mind that the DataSocket server platform is only supported by the Windows operating system.  However the DataSocket client platform is supported by both Windows and Mac OS (Which products support DataSocket).

I hope this helps!  Please let us know if you have any further questions.
