14. Data Interfaces
14.1 Operating Modes
For data transfer the TNC can be switched to the following 5 interface operating modes:
q
ME
For connection of the HEIDENHAIN Magnetic Tape Unit
ME or other peripheral units
(e.g. printer); data transfer in standard data format; data format data bits, 1 stop bit, even parity)
and Baud rate (2400
adapted to the ME.
For connection of the HEIDENHAIN Floppy Disk Unit
FE 401 or other peripheral units
personal computer with HEIDENHAIN data transfer software). Data are transferred with a special
protocol (blockwise transfer) for data security. Data format 17 data bits, 1 stop bit, even parity) and
the transfer protocol are adapted to the FE 401. the interface mode FE 2 the file names must
be noted down for output of machine parameters, compensation value lists and PLC-programs,
as the directory of the external data medium cannot be displayed by the TNC and the file name
is needed again for data input.
If the floppy disk unit FE 401 is used as an external data medium, no letters are permitted
in program names.
When using the FE 401 the Baud rate at the control must be set to 9600
For connection of the HEIDENHAIN Floppy Disk Unit
FE 4018 (or FE 401, software version
230 626 03 and later) or other peripheral units. Data are transferred with a special protocol
(blockwise transfer) for data security. Data format (7 data bits, 1 stop bit, even parity) and the
transfer protocol are adapted to the FE 401/B. The disk directory is automatically displayed by
the TNC
sequence).
All characters are permitted for program names.
The Baud rate set at the TNC must always match that of the FE 410/B.
Possible Baud rates are 2400, 4800, 9600, 19 200 and 38 400.
To adapt the transfer of data to external units in standard data format and for blockwise transfer.
The interfaces for data transfer are adapted via machine parameters.
Any Baud rate may be selected.
Peripheral units for the EXT operating mode are:
Tape punching units and punched tape readers
Printers or matrix printers for graphic printouts
Mass storage media or programming stations for “Blockwise Transfer”
Programming stations and personal computers for external programming
The Baud rate set at the TNC must always match that of the peripheral unit.
Possible Baud rates: 1 to 38 400.
