Issue Details

I am receiving Error -307853 when trying to deploy a VeriStand project to a LabVIEW Real-Time target.

Error -307853 occurred at Project Window.lvlib:Project >> Project Window.lvlib:Command >> NI_VS Workspace ExecutionAPI.lvlib:NI VeriStand - Connect to

Possible reason(s):
NI VeriStand: The VeriStand Gateway was unable to establish a connection with the target. Confirm that the target is running and that the VeriStand Engine successfully has started. If you still cannot connect to the target, use MAX to reinstall the NI VeriStand Run-Time Engine to the target.


This error can occur if the VeriStand Real-Time Engine is not installed on the Real-Time target or has become corrupted.
  1. Reformat the target to clear all software from the controller.
  2. Install the VeriStand Real-Time Engine to the device.

Additional Information

This error will occur if connect or deploy to the target from LabVIEW. The LabVIEW Real-Time executable deployed to the RT target will inhibit the VeriStand Real-Time Engine from being able to run on the target, necessitating a reinstall of the VeriStand software on the target.
