How to Clear the backup in a Quantum 140CPU43412U

Connect to the CPU43412 with Unity. Erase the Backup copy of the program by selecting Backup Clear in the Unity >> PLC >> Project Backup Menu.
If it reports that the backup is invalid, perform a Backup Save followed by a Backup Clear. The next time a download to the CPU is executed, the new project will not be backed up. It will remain cleared until the next Backup Save.
