Issue Details

I have built two executables, can I share data between them using a global variable that is not embedded in either executable?

Solution

No, global variables cannot share data between executables. Each executable uses its own memory space. So global variables can only share data with subVIs within a single executable. However, there are other methods for communicating between executables which are detailed in "Additional Information" below.

Additional Information

There are a few other methods of communicating between executables using LabVIEW:
  1. TCP/IP or UDP
  2. Network Streams
  3. Communicate Between Multiple LabVIEW Executables Using Shared Variables
