Hello Rick,
Reflective memory is intended to accomplish your desired behavior by allowing you to access channels between multiple targets.
Another option would be to use the Shared Variable Custom Device. This would require you to have variables created outside of VeriStand that you could then read and write to from VeriStand.
You can also create your own Custom Device to pass data between targets through Network Streams, TCP, or other network communication protocols.
