OPERATION

Of the external input/output devices, the FANUC Handy File and FANUC
Floppy Cassette use floppy disks as their input/output medium.
In this manual, an input/output medium is generally referred to as a
floppy. However, when the description of one input/output medium
varies from the description of another, the name of the input/output
medium is used. In the text below, a floppy represents a floppy disk.
Unlike an controller tape, a floppy allows the user to freely choose from
several types of data stored on one medium on a file–by–file basis.
Input/output is possible with data extending over more than one floppy
disk.
The unit of data, which is input/output between the floppy and the CNC
by one input/output operation (pressing the [READ] or [PUNCH] key),
is called a “file”. When inputting CNC programs from, or outputting
them to the floppy, for example, one or all programs within the CNC
memory are handled as one file.
Files are assigned automatically file numbers 1,2,3,4 and so on, with the
lead file as 1.

When one file has been entered over two floppies, LEDs on the adaptor
flash alternately on completion of data input/output between the first
floppy and the CNC, prompting floppy replacement. In this case, take the
first floppy out of the adaptor and insert a second floppy in its place. Then,
data input/output will continue automatically.
Floppy replacement is prompted when the second floppy and later is
required during file search–out, data input/output between the CNC and
the floppy, or file deletion.

The request to exchange the floppy disk is issued, if the second or
subsequent floppy disk becomes necessary when a search is being made
for a file, data input/output is being carried out between the CNC and the
floppy disk drive, or a file is to be deleted.
Since floppy replacement is processed by the input/output device, no
special operation is required. The CNC will interrupt data input/output
operation until the next floppy is inserted into the adaptor.
When reset operation is applied to the CNC during a request for floppy
replacement, the CNC is not reset at once, but reset after the floppy has
been replaced.
