Function
The TNC allows you to carry out Teleservice. To be able to use this
feature, your TNC should be equipped with an Ethernet card which
achieves a higher data transfer rate than the serial RS232-C interface.
With the HEIDENHAIN TeleService software, your machine tool
builder can then establish a connection to the TNC via an ISDN modem
and carry out diagnostics. The following functions are available:
n
On-line screen transfer
n
Polling of machine states
n
Data transfer
n
Remote control of the TNC
Generally, a connection via the Internet would also be possible. First
tests have shown, however, that the transfer rate that can currently
be achieved is not sufficient due to the high degree of utilization of the
networks.
