Reading/Writing a Memory Card

You can read/write data into/from a memory card to back up and update a system by means of the DIP switch on a CPU.
8.5.1.

Backing up the System

When a system backup is executed, the user program (including G-code, E-CAM..), the parameter setting, the hardware
configuration, the network (e.g. EtherCAT) configuration, and the values on the device memories in a CPU are backed up
and saved as a file called AUTOEXEC.dup, which is stored in a folder named SysDup in a memory card. If a default path
denotes an existing backup file, the previous data in the old backup file is overwritten when a system is backed up.
A system backup can be executed, whether a CPU runs or stops. Please refer to Section 8.7 Backup for the system
backup procedure.
8.5.2.

Restoring the System

Before a system restoration is executed, you have to make sure that the backup file AUTOEXEC.dup is stored in a folder
named SysDup in a memory card. After the system restoration is executed, the user program, the parameter setting, the
hardware configuration, and the network configuration in the memory card are restored to a CPU. In addition, if the data in
the backup file includes the values on the device memories, the data restored to the CPU will include the values on the
device memories.
If :/PLC CARD/AH500/SysDup/AUTOEXEC.dup is valid, the CPU will restore the system automatically after
power-on.Please be sure not to put this file in SD card if you don't want to restore the system.You can restore the system
by using Card Utility.Please refer to Section 8.9 Restoration.

CARD Utility

There is a microSD slot on AH Motion Controller CPUs. You can back up/restore data in an AH Motion Controller CPU
through the use of a memory card. Besides, ISPSoft provides CARD Utility for AH Motion Controller CPUs. You can back
up/restore data in an AH Motion Controller CPU or an ISPSoft project through CARD Utility. The program code, the
parameter setting, the hardware configuration, and the network configuration in an AH Motion Controller CPU or an
ISPSoft project can be backed up. The values in the devices in an AH Motion Controller CPU can also be backed up.
Please refer to previous sections or the AH Motion Controller - Hardware Manual for more information about the
specifications of the SD cards which can be inserted into AH Motion Controller CPUs, and the usage of the SD cards.
The network configuration stored in an AH Motion Controller CPU is the data which is only related to the AH Motion
Controller CPU itself. When you back up the network configuration, only the part of the network configuration which is
related to the selected AH Motion Controller CPU will be backed up. The part of the network configuration backed up
consists of only a routing table and data exchange data. Therefore, if you restore the backup data to an ISPSoft project,
the system will not be able to restore the complete data in the NWCONFIG settings.
The functions supported by CARD Utility are described below. The diagram below is a flowchart.
 If you export data in an AH Motion Controller CPU as a backup file (*.dup), the data exported can be saved in the
_8
memory card inserted in the AH Motion Controller CPU, or a folder in the computer. You can decide whether to include
the values in the devices in the AH Motion Controller CPU.
 If you export an ISPSoft project as a backup file (*.dup), the ISPSoft project exported can only be saved in a folder in
the computer, and the values in the devices in the AH Motion Controller CPU are not backed up.
 You can restore the backup file (*.dup) in the inserted memory card to the CPU.
 You can restore the backup file (*.dup) in a computer to the CPU which is connected, or restore the backup file to an
