What causes a 'Transfer error: negative UMAS response' when using the Unity Loader to transfer a project to an M340 PLC?



This error means that the M340 project was last Built with Unity Pro in Simulator Mode rather than Standard Mode. Open the M340 project with Unity Pro and Rebuild the project in Standard Mode.
