SCADE Suite Gateway for VeriStand R14

Issue Details

I have compiled a SCADE model for VeriStand using the online tutorial . When I try to deploy it on my real-time target, the deployment fails with the following error :
Error -307703 occurred at Project Window.lvlib:Project >> Project Window.lvlib:Command >> NI_VS Workspace ExecutionAPI.lvlib:NI VeriStand - Connect to



SCADE is compatible with NI VeriStand only starting at version R16. All previous versions of SCADE models compiled for NI VeriStand may results in this deployment error. To solve this issue, update to the latest version of SCADE.

Additional Information

Depending on the version of SCADE and NI VeriStand, the compiled model may be working on Windows but not a Real-Time Operating System.
