Note
USB devices
For SINUMERIK 828D, "usb" (without partition data!) can also be defined as target for a USB
device inserted at the front. The device at the USB can be addressed from the part program
only directly using a symbolic device identifier "/dev/ext/x".
For SINUMERIK 840D sl, only statically connected USB interfaces of a TCU can be
configured as USB devices. The configuration is realized using the SERVER:/PATH type as
specification for "Server" in the sense above, whereby SERVER is the TCU name and /PATH
designates the USB interface. The USB interfaces of a TCU are addressed using "dev0-0",
"dev0-1", "dev1-0". The path data always starts with "/Partition", whereby the partition can be
specified using a two-digit partition number or its partition name – and where required, is
extended with a file path up to the required target, e.g.:
/dev/ext/8 = "TCU4:/dev0-0, /01/, A"
/dev/ext/8 = "TCU4:/dev0-0, /01/mydir.dir/"
/dev/ext/8 = "TCU4:/dev0-0, /myfirstpartition/Mydir.dir/myfile.txt, O"
