LabVIEW saves the TCPIP connection ID as a unsigned 32 bit
number. If you create a LabVIEW VI with the connection ID as an
indicator and link it to the output terminal, then load the prototype
for the VI in TestStand, TestStand will assign U32 Number as the
type. You will have to pass the connection ID to other LabVIEW
VIs only, because the connection ID is something unique to the TCP/IP
LabVIEW functionallity. You should be able to pass the Number and
use it in other LabVIEW VIs without a problem.
