USB devices on the TNC
Caution: Data may be lost!
Only use the USB interface for transferring and
saving, not for processing or running programs.
Backing up data from or loading onto the TNC is especially easy
with USB devices. The TNC supports the following USB block
devices:
Floppy disk drives with FAT/VFAT file system
Memory sticks with the FAT/VFAT file system
Hard disks with the FAT/VFAT file system
CD-ROM drives with the Joliet (ISO 9660) file system
The TNC automatically detects these types of USB devices when
connected. The TNC does not support USB devices with other file
systems (such as NTFS). The TNC displays the USB: TNC does not
support device error message when such a device is connected.
If an error message is displayed when connecting a
USB data medium, check the setting in the SELinux
security software.
Further Information:
page 98
The TNC also displays the USB: TNC does not
support device error message if you connect a USB
hub. In this case, simply acknowledge the message
with the CE key.
In theory, you should be able to connect all USB
devices with the file systems mentioned above
to the TNC. It may occur that a USB device is not
correctly detected by the control. In such cases, use
another USB device.
Working with USB devices
Your machine tool builder can assign permanent
names for USB devices. The machine manual
provides further information.
The USB devices appear as separate drives in the directory tree, so
you can use the file management functions described in the earlier
chapters.
If a larger file is transferred to a USB device in the file
management, the control displays a dialog Write access on USB
device until file transfer is completed. The dialog is closed with
the soft key VERBERGENand file transfer is continued in the
background. The control displays a warning until file transfer is
completed.
