9.3 Using the USB host port
CODESYS applications can be backed up, restored and transferred via the USB functions. In ad-
dition, the device firmware can be updated via the USB interface.
NOTE
The USB host function can be deactivated via the web server or the CODESYS pro-
gram.
FAT or FAT32 formatted USB sticks can be connected to the USB host port. It is not possible to
connect NTFS-formatted sticks or USB devices such as external hard disks, keyboards, PC mice
etc.
Depending on the power consumption of the USB stick, compatibility problems may occur. To
ensure error-free data exchange, Turck recommends using the industrial USB stick USB 2.0 In-
dustrial Memory Stick (Ident-No. 6827348).
