When going online to a CPU Unit from the Sysmac Studio,
the CPU Unit name in the project is compared to the name
of the CPU Unit being connected to.
You can prevent reading data in the CPU Unit from the Sys-
mac Studio.
You can prevent writing data to the CPU Unit from the Sys-
mac Studio or SD Memory Card.
You can use passwords to protect .smc files from unauthor-
ized opening on the Sysmac Studio.
You can use passwords to protect POUs on the Sysmac Stu-
dio.
Online operations can be restricted by operation rights to
prevent damage to equipment or injuries that may be caused
by operating mistakes.

The user program cannot be executed without entering a
user program execution ID from the Sysmac Studio for the
specific hardware (CPU Unit).
SD card or SDHC card
When the power supply to the Controller is turned ON, the
data that is stored in the autoload directory of the SD Mem-
ory Card is transferred to the Controller.
You can perform file operations for Controller files in the SD
Memory Card and read/write general-purpose document
files on the computer.
Notification of the expiration of the life of the SD Memory
Card is provided in a system-defined variable and event log.
Backup, verification, and restoration operations are per-
formed by manipulating the front-panel DIP switch on the
CPU Unit.
Backup and verification operations are performed by manip-
ulating system-defined variables.
Backup and verification operations are performed from the
SD Memory Card Dialog Box of the Sysmac Studio.
The special instruction is used to backup data.
Backing up data to a SD Memory Card is prohibited.
The Sysmac Studio is used to backup, restore, or verify Con-
troller data.
