Appendix B USB Flash Drive Update Function

DOP series HMI, which provides USB flash drive update function, has a built-in USB host interface. The user

can connect HMI to a USB flash drive via this USB host interface and download HMI screen data and

upgrade the firmware of HMI. It also provides encryption and copy times setting function to protect the data

from unauthorized access or use.

There are two modes provided when copying screen data via a USB flash drive. They are Encryption mode

and No Encryption mode. If Encryption mode is selected, the screen data will be encrypted and copying of

the screen data is an act restricted by the copy times setting of HMI. Choosing Encryption can effectively

protect the intellectual property rights and avoid the user design not to be stolen. If No Encryption mode is

selected, there is no limit for copying the screen data and the user can use and download the screen data

freely.

Encryption Mode

As shown as the Fig. B.1 below, before selecting Encryption mode, the user should click Options >

Configuration to enter Standard tab and select “Enable USB updating check” this option. The encryption

and copy times setting function of HMI cannot be used if this option is not selected.
