how to save a TCP session ID opened and use it in another VI?

[yongjian]

what i want to achieve:

   open a TCP session in a VI, save the session ID to Teststand, then after certain process, write/read/close the same TCP session in another VI.

my question:

   1. how to pass TCP session ID between labview and Teststand

   2. how to use the same TCP session across different VIs.

thanks

You  could typecast the reference to a U32 and sent that u32 to Teststand.

Be aware that the VI that opens the reference should be kept active (=running) or LabVIEW might close the reference silently.
