6.4 Remote maintenance via modem
Siemens offers a TS ada pter which can be used for remote maintenance. This adapter is connected
between the MPI connection of the PLC a nd a commercial modem. The programming device which is
also equipped with a modem can now communicate with the PLC via a standard telephone connection.
Instead of using the programming device to carry out the remote maintenance, you can also use the
bus server installed at a PC equipped with a modem.

• The connection with the remote maintenance system always has to be established manually.
• The bus server may only be started after the co nnection has been established, otherwise
