*1. To use Safe Mode, set the DIP switch as shown below and then turn ON the power supply to the Controller.

If the power supply to the Controller is turned ON with the CPU Unit in Safe Mode, the CPU Unit will start in PROGRAM mode. Use the Safe Mode if you do not want to execute the user program when the power supply is turned ON or if it is difficult to connect the Sysmac Studio.

For information on Safe Mode, refer to the NJ/NX-series Troubleshooting Manual (Cat. No. W503).

*2. Refer to the NJ/NX-series CPU Unit Software User’s Manual (Cat. No. W501) for details on backing up data.
