USB devices on the TNC

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.

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 happen that a USB device is not

identified correctly by the control. In such cases, use

another USB device.

The USB devices appear as separate drives in the directory tree, so

you can use the file-management functions described in the earlier

chapters correspondingly.

Your machine tool builder can assign permanent

names for USB devices. Refer to your machine

manual.
