2-3 USB Memory Devices
This section describes how to use a USB Memory Device to transfer the project or save log data.
USB Memory Devices that comply with the USB 2.0 standard are supported, but use one of the USB
Memory Devices specified by OMRON. (Refer to 1-3-3 Other Optional Products on page 1-6.) OMRON
is not responsible for the operation, performance, or write life of any other USB Memory Device.
You can use the USB Memory Device for the following applications.
• Automatically transferring the project data (which includes the screen data) created on the Sysmac
Studio to the HMI
• Updating the HMI system program
• Recording log data (data log and user alarms)
This section describes methods to install and remove an USB Memory.
Refer to the NA-series Programmable Terminal Software User’s Manual (Cat. No. V118) for information
on subroutines.
Precautions for Correct Use
You can connect only one USB memory device at the same time.
Observe the following precautions while the USB Memory Device is being accessed.
• Before you remove the USB Memory Device, execute EjectUSBDevice in a subroutine.
• Before you turn OFF the power supply to the HMI, execute EjectUSBDevice in a subroutine.
• Never insert the USB Memory Device facing the wrong way.
If the USB Memory Device is inserted forcibly, it may become unusable.
• To format a USB Memory Device (e.g., to delete all of the data), use a Windows formatting utility and
format to FAT32.
• The USB Memory Devices use flash memory, and so their service life is limited. When the end of the
USB Memory Device’s service life approaches, the ability to write data is lost, and data is sometimes
not retained after writing. The service life depends on the size of the data that is written and on the
ambient temperature. For the unlikely event that data is lost, it is recommended to periodically back
up data.
