• When performing online editing, the CPU Unit saves a program updated by the online editing to
built-in non-volatile memory. Sysmac Studio shows a message that it is in a backup operation. Do not
turn OFF the power supply to the Controller while this message is displayed. If the power supply to
the Controller is turned OFF, a Controller error will occur when the power supply is turned ON next
time.
